DESCRIPTION

FDA Compliant -For Direct Contact Food Safe Coating

Sanitizable Barrier Coating For Direct Food Contact


Just measure out two parts Part A to one part Part B, mix and apply and allow to cure overnight. It has a 45-minute working time and can be handled in 6 hours.
 Handling strength will develop in 10 hours of room temperature curing and will fully cure within 24 to 36 hours.
Heat curing is also ideal for faster cure time. 

The mixed consistency is similar to a very light syrup (800 cPs).

MAX CLR A/B is a two-component epoxy resin system that is produced in compliance with FDA regulations intended for direct food contact coatings and adhesive applications.
MAX CLR A/B is thermoset polymer resin that cures crystal clear and demonstrates high chemical resistance to acidic and basic compounds.
It is resistant to dilute grain alcohol and can withstand brief contact with hot fluids (up to 187°F) such as coffee, tea, and soups.
The commercial serving temperature of hot beverages (coffee, tea and soups)is between 150°F to 167°F.

The primary purpose of the MAX CLR resin system is to create a sanitizable coating that demonstrates low extractable of its chemical constituents during direct food contact.
Equally, the objective goal of the cured coating is to create a durable barrier when applied onto a porous substrate such as wood.
The cure MAX CLR coating prevents absorption of fluids or organic compounds that allows bacterial colonization or microbial growth to occur.  

All components used to formulate the MAX CLR resin system are in compliance with the
Code of Federal Regulations, Title 21, Part 175 for resinous coatings/adhesive subject to direct and indirect food contact.

IMPORTANT GUIDELINES FOR FOOD CONTACT APPLICATIONS
For food contact applications, MAX CLR A/B must be fully cured to ensure no chemical leaching can occur when foodstuffs' come in contact with the cured resin system. Any uncured chemical compounds caused by improperly prepared MAX CLR may be extracted and cause cross-contamination or leaching during food contact. Please review the following and to avoid any curing problems.

USE AND APPLICATION

Precondition both bottles to 75°F and measure the components accurately at a 2:1 mix ratio; 100 parts resin to 50 parts curing agent.
The substrate must be suitable and prepared for the intended purpose of the application.
Remove any contaminants that may interfere with the adhesion of the MAX CLR resin system.
Exclude the use of materials and components not suitable for food contact (lead-based pigments, harsh cleaners, and unsanitary conditions).
Old coatings should be removed to ensure the best adhesion and surface quality.

The use of a weighing scale is recommended over volumetric measuring.
Any off-ratio excess of either the resin or curing agent can cause poor cure results and cause excessive chemical leaching that can transfer to the food or beverage.
Purchase a scale with any of product offering and the shipping cost of the scale is free.
Please request a total before paying for combined shipping savings. Any shipping over payments will be refunded at the end of the sale.

PRACTICAL GUIDE ON HOW TO USE THIS RESIN SYSTEM

Review All Published Data Regarding This Product
Proper Usage Data And Other Detailed Information Are Posted At This Page
Mix the Resin And Curing Agent Only After The Surface Is Prepared For Application

STEP 1. SURFACE PREPARATION
The quality of adhesion of any coating or adhesive application is dependent on how well the surface is prepared.
The resin system must be able to properly 'wet-out' the surface to form a continuous film. Surfaces demonstrating poor wettability prevents the liquid resin from forming a cohesive bond.
Improper surface wetting yields poor adhesion and will delaminate during use.
Wetting is the ability of a liquid to interfaces or wet-out a solid surface; its dynamics is expressed as surface tension.

A surface that demonstrates low surface tension, such as waxed surface, oily surface or slick plastics like Teflon will prevent the liquid resin to wet-out and cause poor adhesion.
In the same respect, if the surface is coated from a previous application, the epoxy adhesion is limited to adhesion quality of the primary coating is applied over.
Make sure to remove any loose or peeling old coating before application to avoid delamination.
If possible remove the old coating by mechanical sanding or power washing so the applied epoxy is in direct contact with the base substrate.
Applying a coating over an oil-based stain should be avoided.

Poor Wetting Of The MAX CLR Resin (Crawling) Due To Oil-based Stain Applied On Wood
Applying a coating over a painted, treated or contaminated surface can cause the epoxy coating to retract into a discontinuous application.
This phenomenon is called 'crawling' which indicates that the surface is low in surface tension making it difficult for the liquid coating to wet-out the surface.
The poor wetting or hydrophobicity is commonly caused by oils-based wood stains and other wood treatments.
And, if the surface has been previously coated or painted making the surface unwettable.

 

This hydrophobic characteristic is commonly seen in nature when leaves repel water that keeps the surface dry.

Testing And Preparing The Surface To Improve Wetting And Eliminate Crawling

Why Epoxy Coatings Bead-up. Testing & Preparing Surface 


With proper surface preparation, such as light sanding and solvent cleaning,
the surface tension will increase, making it wettable, and epoxy coating can be applied with no film crawling.

The Following Surface Preparation Procedures Are Recommended. 

METALS AND CONCRETE

Degrease Metals– Wipe surface with a lint-free rag dampened with Methyl Ethyl Ketone (MEK) or acetone to remove all oil, dirt, and grease.

Degrease Concrete- Use 2 cups of TSP (trisodium phosphate) detergent per 5 gallons of hot water and scrub with a stiff deck brush. Rinse with water and allow to dry.

Etch Metals – For optimum results, metal parts should be immersed in a chromic acid bath solution consisting of:

Sodium Dichromate

4 Parts By Weight

Sulfuric Acid

10 Parts By Weight

Water

30 Parts By Weight

The solution is held at 160°F (71°C), and the parts left immersed for 5 to 7 minutes. Rinse – remove metal parts from etching bath and rinse with clean water. (distilled water is recommended).

Etch Concrete- Use commercially sold concrete etching solution (hydrochloric acid based works best). Neutralized per instructions, rinse and allow to dry thoroughly.

ALTERNATE PROCEDURE 
Degrease, scour and dry – Often etching as outlined above is not practical. The metal surfaces may be cleaned by degreasing as noted above, scouring with an alkaline cleanser followed by rinsing and drying.

Degrease and dry – Degrease the surface as noted above, sand or sandblast the surface lightly but thoroughly. Rinse with acetone or Methyl Ethyl Ketone (MEK), and dry.

GLASS

Degrease – With MEK as above, or with a strong boiling solution of a good grade household detergent.

Etch – For optimum results, degreasing can be followed by the chromic acid bath outlined above.

WOOD

Sand – Bonding surfaces should be sanded lightly, but thoroughly to remove all external contamination.

Clean – Carefully remove all dust, or particles of wood from sanded areas. A stiff and clean brush or compressed air can be used.

PLASTIC

Clean – Remove all dirt, oil, or other surfaces contaminated with detergent soap or degreasing solvent and water, followed by thorough rinsing and drying. A solvent that does not have a detrimental effect may also be used.

Sand – Surfaces to be bonded should be sanded lightly, but thoroughly to remove surface sheen.

Clean – Carefully remove all dust or particles of plastic from the sanded area. A clean brush, lint-free cloth, or compressed air may be used.

STEP 2. CHECK THE PART A OR RESIN BOTTLE FOR CRYSTALLIZATION

During the winter months, the PART A or RESIN component may crystallize and cause poor cure performance.
Our MAX Epoxy Resins are formulated with high purity grade resin polymers which makes it prone to crystallization when exposed to temperatures below 57°F.
Crystallization can also occur after the resin has been stored over a period.
It will appear as a waxy white mass at the bottom of the bottle.
The PART A or RESIN component must be in its liquid form to thoroughly mix with the PART B or curing agent to achieve full cure. 

DO NOT USE UNLESS PROCESSED

View the following video for identification and processing.


STEP 3. DETERMINE THE AMOUNT THE BATCH SIZE NEEDED

Calculate the amount to be mixed by measuring the length x width x thickness of the area to be coated to obtain the cubic volume of the resin needed. 

Begin by mixing a small batch to gain experience with the polymerization process of the MAX CLR resin system.
Blending amounts greater than 1000.0 grams or 1 quart in volume requires careful mixing and ensuring the mixed resin is applied and used within the established working time.
Applying the mixed resin beyond the working time limit or when the mixed resin starts to generate heat creates cured problems .
Do not let the mixed resin to sit in mass greater than 90°F to prevent exothermic "run-away" reaction.

The heat generated during polymerization will accelerate the chemical reaction and cause a 'run-away' reaction to occur.
It can generate temperatures above 300°F and cause an uncontrollable chemical reaction.
Mix the proper amount of resin and curing agent and apply within the established working time to avoid causing and exothermic 'run-away' reaction

Use These Factors To Convert Volumetric Or Weight Measurements

Fluid Gallon To Volume Conversion
1 Gallon = 231 Cubic Inches
1 Gallon = 128 Ounces
1 Gallon = 3.7854 Liters
1 Gallon  = 4 Quarts
1 Gallon  = 16 Cups

Fluid Gallon Mass Conversions
1 Gallon Of Mixed Unfilled Epoxy Resin = 9.23 Pounds
1 Gallon Of Mixed Unfilled Epoxy Resin = 4195 Grams

Take into account that some of the coating thickness will get absorbed into the porosity. Mix a batch of the MAX CLR and apply (brush, roller or squeegee) the mixed coating onto the substrate first, and allow the application to impregnate and absorb into the porosity. Allow to cure until it has set dry to the touch for 8 to 12 hours. The first application seals the surface porosity and prevents further resin absorption and eliminate air bubbles from outgassing from the surface.  

STEP 4. MIXING PROCEDURE

The two components must be mixed thoroughly to eliminate problems such as tacky or uncured spots.
Use the "two container method" as demonstrated in this video demonstration, which ensures a homogeneous mixture of the resin and curing agent.

STEP 5. APPLICATION DEMONSTRATIONS

Condition the ambient temperature to 75°F for best results. Ensure that the work area is dust free and well ventilated. MAX CLR is self-leveling and will continue to flow until it polymerization converts it to a solid phase. It can be applied by using a bristle or high-density foam brush/roller or poured into place. MAX CLR is self-leveling, ensure the surface is level and secure any leaks by using tape to create a temporary patch and prevent leakage.

When sealing wood substrates, the first application causes 'grain-raising' to occur. Allow the MAX CLR to cure for 12 hours and lightly sand the surface with fine sandpaper to remove the grain raising. For concrete and fibrous surfaces, the top coat can be directly applied with no sanding between coats.

What Is 'Grain Raising'?

  • When a liquid coating is applied over wood, fibers will begin to swell, and this will produce 'grain raising' to occur.
  • Raised grains are small end fibers protruding from the coating causing unsightly unevenness.
  • Allow the applied resin to cure and lightly sand the surface using fine-grit sandpaper.
  • Remove dust and debris by wiping with a lint-free rag dampened with alcohol or acetone and allow to dry.
  • Once the surface is prepared, apply the second coat of MAX CLR which will yield a smooth blemish free coating.

STEP 6. CURING
To achieve the best cure results, the ambient condition should be between 75°F to 85°F and the relative humidity is below 80%.

Allow to cure for 3 days before allowing direct-food contact
The colder the temperature the longer takes to fully cure.

Use an infrared lamp to warm the ambient temperature.
Infrared lamps also work well for warming large work areas.

Post Curing at 150°F for 2 hours after 24 hours room temperature cure accelerates full curing.

Rinse the surface with warm water and mild detergent before use.

EASY STEPS FOR DEGLOSSING

Once the MAX CLR fully cures, deglossing the surface to create a satin finish can be easily done using an abrasive pad.
In this demonstration, a SCOTCHBRITE pad was used to de-gloss the surface.
Note the dramatic decrease in gloss after a light polishing with the abrasive pad. Very-fine sandpaper (wet-sanding) also works well.

Step One: Fabric Selection
TYPES OF FABRIC WEAVE STYLE AND SURFACE FINISHING
FOR RESIN TYPE COMPATIBILITY

Fabrics are generally considered ”balanced” if the breaking strength is within 15% warp to fill and are best in bias applications on lightweight structures.
“Unbalanced” fabrics are excellent when a greater load is required one direction and a lesser load in the perpendicular direction.
Most fabrics are stronger in the warp than the fill because higher tension is placed on the warp fiber keeping it straighter during the weaving process. Rare exceptions occur when a larger, therefore stronger thread is used in the fill direction than the warp direction.

Step Two: 
Choose The Best Epoxy Resin System For The Application
The epoxy resin used in fabricating a laminate will dictate how the FRP will perform when load or pressure is implied on the part.
To choose the proper resin system, consider the following factors that is crucial to a laminate's performance.
Size And Configuration Of The Part
(Number Of Plies  And Contoured, Flat Or Profiled)
Consolidating Force
(Free Standing Dry Or Hand Lay-up, Vacuum Bag Or Platen Press Curing)
Curing Capabilities
(Heat Cured Or Room Temperature Cured)
Load Parameters
(Shearing Force, Torsional And Directional Load, Beam Strength)
Environmental Exposure

The Principal Role Of The Resin Is To Bind The Fabric Into A Homogeneous Rigid Substrate
(Operating Temperature, Ambient Conditions, Chemical Exposure, Cyclic Force Loading)
Material And Production Cost
(Buying In Bulk Will Always Provide The Best Overall Costs)
These factors will dictate the design and the composition of the part and must be carefully considered during the design and engineering phase of the fabrication.

Step Three:
Proper Lay-Up Technique -Putting It All Together
Pre-lay-up notes
Lay out the fabric and pre-cut to size and set aside
Avoid distorting the weave pattern as much as possible
For fiberglass molding, ensure the mold is clean and adequate mold release is used
View our video presentation above "MAX EPOXY RESIN MIXING TECHNIQUE"
Mix the resin only when all needed materials and implements needed are ready and within reach.

Mix the proper amount of resin needed and be accurate proportioning the resin and curing agent.
Adding more curing agent than the recommended mix ratio will not promote a faster cure.

Over saturation or starving the fiberglass or any composite fabric will yield poor mechanical performance.
When mechanical load or pressure is applied to the composite laminate, the physical strength of the fabric should bear the stress and not the resin.
If the laminate is over saturated with the resin it will most likely to fracture or shatter instead of rebounding and resist damage.
Don’t how much resin to use to go with the fiberglass?
A good rule of thumb is to maintain a minimum of 30 to 35% resin content by weight.

This is the optimum ratio used in high-performance prepreg (or pre-impregnated fabrics) typically used in aerospace and high-performance structural application.
For general hand lay-ups, calculate using 60% fabric weight to 40% resin weight as a safety factor.
This will ensure that the fabricated laminate will be below 40% resin content depending on the waste factor accrued during fabrication.

Place the entire pre-cut fiberglass to be used on a digital scale to determine the fabric to resin weight ratio.
Measuring by weight will ensure accurate composite fabrication and repeatability, rather than using OSY (ounces per square yard) or GSM ( grams per meter square) data.

THE USE OF A WEIGHING SCALE IS HIGHLY RECOMMENDED 

Purchase this scale with any of our product offering and the shipping cost of the scale is free.

A good rule of thumb is to maintain a minimum of 30 to 35% resin content by weight.
For most fabrics and application this is the optimum ratio used in high-performance prepreg (or pre-impregnated fabrics) typically used in aerospace and high-performance structural application.
For general hand lay-ups, calculate using 60% fabric weight to 40% resin weight as a safety factor.
This will ensure that the fabricated laminate will be below 40% resin content depending on the waste factor accrued during fabrication.

Place the entire pre-cut fiberglass to be used on a digital scale to determine the fabric to resin weight ratio. Measuring by weight will ensure accurate composite fabrication and repeatability, rather than using OSY data.

Typical fabric weight regardless of weave pattern
1 ounce per square yard is equal to 28.35 grams
1 square yard equals to 1296 square inches (36 inches x 36 inches)

FOR EXAMPLE
1 yard of 8-ounces per square yard (OSY) fabric weighs 226 grams
1 yard of 10-ounces per square yard (OSY) fabric weighs 283 grams

Ounces per square yard or OSY is also known as aerial weight, which is the most common unit of measurement for composite fabrics.
To determine how much resin is needed to adequately impregnate the fiberglass, use the following equation:

(Total Weight of Fabric divided by 60%)X( 40%)= weight of mixed resin needed
OR
fw= fabric weight
rc= target resin content
rn=resin needed

MASTER EQUATION
(fw/60%)x(40%)=rn
FOR EXAMPLE
1 SQUARE YARD OF 8-OSY FIBERGLASS FABRIC WEIGHS 226 GRAMS
(226 grams of dry fiberglass / 60%) X 40% = 150.66 grams of resin needed
So for every square yard of 8-ounce fabric, it will need 150.66 grams of mixed resin.
Computing For Resin And Curing Agent Amount
150.66 grams of resin needed

MIX RATIO OF RESIN SYSTEM IS 2:1
Or
50 PHR (per hundred resin)
2 = 66.67% (2/3)+1 = 33.33%(1/3)
=
(2+1)=3 or (66.67%+33.33%)=100% or (2/3+1/3)= 3/3

150.66 x 66.67%= 100.45 grams of Part A RESIN
150.66 x 33.33%= 50.21 grams of Part B CURING AGENT

100.45 + 50.21 = 150.66  A/B MIXTURE

GENERAL LAY-UP PROCEDURE
Apply the mixed resin onto the surface and then lay the fabric and allow the resin to saturate through the fabric.

NOT THE OTHER WAY AROUND

This is one of the most common processing error that yields sub-standard laminates. By laying the fiberglass onto a layer of the prepared resin, less air bubbles are entrapped during the wetting-out stage. Air is pushed up and outwards instead of forcing the resin through the fabric which will entrap air bubbles. This technique will displace air pockets unhindered and uniformly disperse the impregnating resin throughout the fiberglass.

VACUUM BAGGING PROCESS
 For performance critical application used in aerospace vehicles, composite framing for automotive vehicles and marine vessels, a process called 'Vacuum Bagging' is employed to ensure the complete consolidation of every layer of fabric. 
The entire tooling and lay-up are encased in an airtight envelope or bagging and a high-efficiency vacuum pump is used to draw out the air within the vacuum bag to create a negative atmospheric pressure. Once a full vacuum (29.9 Inches of Mercury) is achieved, the negative pressure applies a compacting force of 14.4 pounds per square inch (maximum vacuum pressure at sea level) is applied to the vacuum bag transferring the force to the entire surface area of the laminate.
Vacuum pressure is maintained until the resin cures to a solid. For room temperature curing resin system, the vacuum pump is left in operation for a minimum of 18 hours. External heat can be applied to the entire lay-up, thus accelerating the cure of the resin system.
The vacuum force also removes any entrapped air bubble between the layers of fabric and eliminate what is called, porosity or air voids. Porosity within a laminate creates weak spots in the structure that can be the source of mechanical failure when force or load is applied to the laminate.

The standard atmosphere (symbol: atm) is a unit of pressure defined as 1
01325 Pa (1.01325 bar), equivalent to 
760 mm Mercury or 29.92 inches Mercury or
14.696 pounds per square inch of pressure.

AUTOCLAVE CURING PROCESS
 Autoclave curing processing is the most common method used in the large-scale production of composite products.
The Aerospace Industry, which includes space exploration rockets launch vehicles, space structures, and commercial/ military airplane utilizes this composite fabrication aspect.
The mechanical demands of the composite are often pushed to the upper limits and autoclaved process yields composites with the best weight to strength ratio.

BASIC OPERATION OF THE AUTOCLAVE PROCESS
In the autoclave process, high pressure and heat are applied to the part through the autoclave atmosphere, with a vacuum bag used to apply additional pressure and protect the laminate from the autoclave gases. 
The cure cycle for a specific application is usually determined empirically and, as a result, several cure cycles may be developed for a single material system, to account for differences in laminate thickness or to optimize particular properties in the cured part.
The typical autoclave cure cycle is a two-step process. First, vacuum and pressure are applied while the temperature is ramped up to an intermediate level and held there for a short period of time. The heat reduces the resin viscosity, allowing it to flow and making it easier for trapped air and volatiles to escape. The resin also begins wetting the fibers at this stage.
In the second ramp up, the temperature is raised to the final cure temperature and held for a sufficient length of time to complete the cure reaction. During this step, the viscosity continues to drop, but preset temperature ramp rates and hold times then stabilize viscosity at a level that permits adequate consolidation and fiber wetting, while avoiding excessive flow and subsequent resin starvation. 
These control factors also slow the reaction rate, which prevents excessive heat generation from the exothermic polymerization process. Upon completion, the cured mechanical performance of the composite is often much stronger and lighter compared to a hand lay-up, or vacuum bagged composite laminate.

VACUUM INFUSION PROCESS
Vacuum Infusion Process is also known in the composites industry as 
Vacuum Assisted Resin Transfer Molding or VARTM.

Similar to the Vacuum Bagging Process where the negative pressure is used to apply consolidation force to the laminate while the resin cures.
Resin is infused into the fabric lay-up by sucking the impregnating resin and thus forming the composite laminate.

The VARTM Process produces parts that require less secondary steps, such as trimming, polishing or grinding with excellent mechanical properties.
However, the vacuum infusion requires more additional or supplemental related equipment and expendable materials.
So the pros and cons of each presented composite fabrication process should be carefully determined to suit the user's capabilities and needs.

Please view the following video demonstration which explains the process of Vacuum Infusion or VARTM process.

Step Four: Proper Curing
Although we have formulated all of our MAX EPOXY RESIN SYSTEM product line to be resistant to amine-blush, it is recommended not to mix any resin systems in high humidity conditions, greater than 60%.
Make sure that the substrate or material the epoxy resin system is being applied to is well prepared
 as possible to ensure the best-cured performance. 

Review the published data and information for proper usage, application, and general safety information.
Our expert staff of engineers is always available for consultation and assistance.

Allow the lay-up to cure for a minimum of 24 to 36  hours before handling.
Optimum cured properties can take up to 7 days depending on the ambient cure condition. 
The ideal temperature cure condition of most room temperature epoxy resin is 22 to 27 degrees Celsius at 20% relative humidity.
Higher ambient curing temperatures will promote faster polymerization and development of cured mechanical properties.

IMPROVING MECHANICAL PERFORMANCE VIA POST HEAT CURE
 A short heat post cure will further improve the mechanical performance of most epoxy resins.
Allow the applied resin system to cure at room temperature until for 18 to 24 hours and if possible, expose heat cure it in an oven or other sources of radiant heat.

 Proportioning the correct amount is equally as important to attain the intended cured properties of the resin system. The container in which the epoxy and curing agent is mixed is an important consideration when mixing an epoxy resin system. The container must withstand the tenacity of the chemical and must be free of contamination. Most epoxy curing agent has a degree of corrosivity, as a general practice, protective gloves should be worn when handling chemicals of the same nature.
