IMPORTANT GUIDELINES FOR FOOD CONTACT APPLICATIONS

For direct 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.

COLD TEMPERATURE CRYSTALLIZATION
The high purity nature of the resin formulation makes it prone to crystallizing when exposed to temperatures below 57 °F. During the colder season, the MAX CLR  PART A -resin component may crystallize during shipping, especially during the cold season. Resin crystallization can also occur after the container has been stored for a period.
Crystallized resin appears as an opaque white mass on the bottom of the bottle. 

PROCESSING
With the cap securely in place, place the PART A container in a hot water bath (160°F) until the contents are revert back to its liquid state and optically transparent.
Cool the PART A bottle to 75°F and the mix the proper amount of PART B curing agent.
Please view the following video demonstration for processing.

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 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 upon contact.
Mix the resin and curing agent to a uniform consistency.
View the mixing video demonstration video below
The substrate must be prepared for the intended purpose of the application.
Remove any contaminants that may prevent adhesion of the MAX CLR resin system.
Exclude the use of materials and components not suitable for food contact applications (lead-based pigments, solvents and unsanitary conditions).

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.
Allow the MAX CLR to cure for a minimum of 48 hours at 75°F

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 oil-based stain should be avoided.

The Following Surface Preparation Procedures Are Recommended. 

METALS AND CONCRETE Degrease Metals– Wipe surface with 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

STEP 3. DETERMINE THE AMOUNT THE BATCH SIZE NEEDED

Blending amounts greater than 1000.0 grams or 1 quart in volume requires careful mixing.
The mixed resin must be applied and used within the established working time to prevent exothermic "run-away" reaction. Do not let the mixed resin to sit in mass greater than 15 minutes as this produce high exothermic temperatures. The heat generated during polymerization will accelerate the chemical reaction and cause a 'run-away' reaction to occur. Temperatures above 300°F can occur and produce burn hazards.

Mix the proper amount of resin and curing agent and apply within 10-15 minutes to avoid this from occurring.

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. 

Use These Factors To Convert Gallon Needed Into 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

When applying the MAX CLR on a porous surface such bare wood, take into account that the coating will be absorbed.
Some grain raising will occur, which is a normal.
Mix  a batch of the MAX CLR and apply it onto the bare wood,  and allow to cure until it has set dry to the touch.
This will seal the surface porosity as well as prevent air bubbles from outgassing and minimize entrapped air bubbles.

Allow to cure for 16 hours and lightly sand the surface to remove 'grain-raising'.
Clean off the surface to remove sanding debris and the surface is ready for the next coating application.
The coating thickness is a big factor that dictates resin coverage.
For protective coatings, a minimum coating thickness of 0.010-inch or 10 mils is recommended.
Thicker coating thickness up to 0.500 mils or 1/2 inch per can be applied, however consider the exothermic heat the resin produces when cured in a concentrated mass.
The larger the mass the higher the exothermic temperature is generated.

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 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.

STEP 6. PROPER CURING FOR DIRECT FOOD CONTACT

Allow the applied resin to cure for a minimum of 48 hours at 75°F before allowing the coating to come in contact with any foodstuffs.
A short post heat cure for 2 hours 200°F after the MAX CLR has cure solid provides enough stability and cure density for further processing and handling.

Rinse the cured coating with warm water and mild detergent before allowing any food contact.

POSSIBLE HEAT CURING TECHNIQUES
If an oven is not available for curing, exposing the assembled part to radiant or solar heat (sun exposure) for a short period will provide enough heat cure for the part to be handled.

CUTTING AND POLISHING

Allow to fully cure for 48 hours before polishing or machining. MAX CLR can be cut, ground or CNC or lathe machined to shape. Polishing improves scratch resistance. The transparency is also restored after machining by wet sanding and then polish with abrasive free wax or polish.

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.
