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) that 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, or 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
[isdntekvideo]
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 to prevent exothermic "run-away" reaction. Do not let the mixed resin to sit in mass greater than 10 minutes. The heat generated during polymerization will accelerate the chemical reaction and cause a 'run-away' reaction to occur that 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.
CALCULATING HOW MUCH RESIN TO MIX FOR SEALER AND TOP COAT BATCH SIZE
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 during cure. The larger the mass, the higher the exothermic temperature is generated, the shorter the working time.
Recommended Sealer Coating Thickness: 0.010 inch
Typical Top Coat Coating Thickness: 0.125 (1/8) Inch

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%. 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 will accelerate full curing.
Rinse the Surface with warm water and mild detergent before use.

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.

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.
