MAX CLR A/B
FDA Compliant For Direct Food Contact Coating
(24 Fluid Ounces Combined Volume)
1 PINT OF MAX CLR PART A -Resin 16 Fluid Ounces
1/2 PINT MAX CLR PART B- Curing Agent 8 Fluid ounces
Upon cure full, MAX CLR A/B is completely inert making it suitable for coating, casting or bonding applications.
The primary purpose of the MAX CLR A/B resin system is to facilitate 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, concrete, foam, and similar materials.

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.
Avoid Coating Retraction Or Crawling \u0026 Improve Bond. Test \u0026 Prepare Surfaces Before Applying Epoxy.

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. Etch Metals – For optimum results, metal parts should be immersed in a chromic acid bath solution consisting of:
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 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.
STEP 3. DETERMINE THE AMOUNT THE BATCH SIZE NEEDEDBlending 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 PROCEDUREThe 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.

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.

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.
