EPOXY RESIN CRYSTAL CLEAR FOOD SAFE COATING SEALING 4 WOOD METAL PLASTIC MAX CLR

Description

MAX CLR A/B
CLEAR LIQUID RESIN
1 PINT 0F MAX CLR PART A;
1/2 Pint Of MAX CLR PART B
(24 OUNCES COMBINED VOLUME)
DESCRIPTION
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 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 hermetic barrier when applied onto a porous substrate (such as wood).
The 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.
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. It can also occur after the container has been stored in an uncontrolled environment. 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.
STORAGE
Secure caps for both bottles after use and store above 65
°F
minimum temperature to prevent re-crystallization.
The resin system will remain viable for at least 12 months or longer.
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.
The substrate must be suitable and prepared for the intended purpose of the application.
Remove any contaminants that may interfere with the complete cure 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).
PROPER CURING BEFORE USE
Allow the applied resin to fully cure for a minimum of 48 hours at 75°F before exposing the coating to any foodstuffs.
A short heat post cure at 150°F for 60 to 90 minutes will ensure the resin is fully cured.
Wash and rinse the cured coating with warm water and mild detergent before allowing any food contact.
Heat Curing Oven
Other heat curing such as infrared heat lamps can be used if a heat chamber or oven is not available.
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 oil-based stain should be avoided.

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
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.
The mixed resin must be applied within the established working time to prevent a "run-away" reaction.
Do not let the mixed resin to sit in mass greater than 10 minutes.
The exothermic heat generated during polymerization will accelerate the chemical reaction and cause a 'run-away' reaction to occur.
A 'run-away' reaction can produce temperatures above 300°F and cause an uncontrollable chemical reaction.
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
Take into account that some of the coating thickness will be absorbed into the porosity.
Mix a batch of the MAX CLR and apply it onto the bare wood first, and allow to cure until it has set dry to the touch.
This application will seal the surface and prevent further absorption.
This initial coating will also prevent air bubbles from outgassing that will cause unsightly bubbles from getting entrapped in the coating.
The sealing application will also cause "grain-raining' to occur.
When a liquid coating is applied over uncoated wood, the wood fiber ends will begin to swell as it gets impregnated with the resin, which
will produce what is called '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.
Once the surface is lightly sanded to remove grain-raising, apply the second coat of MAX CLR which will yield a smooth blemish free coating.
CALCULATING HOW MUCH RESIN TO MIX
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, the shorter the working time
To calculate coating thickness of 0.010-inch or 10 mils is recommended.
Calculation: 1608 / 10 = 160.8 Square Feet 1 Gallon Coverage
For high-build or thick casting of 1/2 inch (500.0 mils)
Calculation: 1608 / 500 = 3.21 Square Feet 1 Gallon Coverage

APPLICATION DEMONSTRATIONS
Condition the ambient temperature of the work area 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.

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.
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 p
olish 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.

EVERYTHING YOU NEED TO MEASURE, MIX, DISPENSE OR APPLY
Proportioning the correct amount is equally as important to attain the intended cured properties of the resin system.
T
he 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.
