Upon Cure, MAX CLR-HP A/B resists extreme and repeated thermal shocks making it well suited for bonding substrates with dissimilar expansion coefficients.
MAX CLR-HP A/B is 100% solids and does not contain Ozone Depleting Chemicals (ODC), non-reactive plasticizers or solvent fillers.
IMPORTANT GUIDELINES FOR FOOD SAFE COATINGS APPLICATIONS
MAX CLR-HP 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-HP 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) that prevents absorption of fluids or organic compounds that allows bacterial colonization or microbial growth.
All components used to formulate the
MAX CLR-HP
resin system are listed in 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-HP
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-HP A/B
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 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 def F and the mix the proper amount of PART B curing agent.
STORAGE
Secure caps for both bottles 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-HP A/B
resin system. Exclude the use of materials and components not suitable for food contact (lead-based pigments, harsh cleaners and unsanitary conditions).
CURING
PROCEDURE
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. 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.
POOR WETTING OF THE RESIN (CRAWLING) DUE TO OIL-BASED STAIN APPLIED ON WOOD
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
View the following video for identification and processing.
STEP 3. DETERMINE THE AMOUNT THE BATCH SIZE NEEDED
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 when allowed to react in mass. 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
Applying the
MAX CLR-HP A/B
on  a porous surface, such bare wood, take into account that the coating will be absorbed.
Mix  a batch of the
MAX CLR-HP A/B
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
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
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 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-HP A/B
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-HP A/B
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.

IMPACT RESISTANCE OF MAX CLR-HP A/B
MECHANICAL PERFORMANCE TEST
Impact testing is one of the most revealing test methods that demonstrate a material's ability to resist and withstand a high-rate of pressure loading, its behaviour during and after the impact can define its maximum mechanical property and conditional limits upon its destruction.
Why is Impact Testing Important?
The impact resistance of an object provides the ultimate measure of its resistance to its definitive destruction. Governed by the many laws and dynamics of physics, a skilled chemist or materials engineer can determine the design equilibrium and ultimate performance by careful analysis of the material’s disassociation and the manner of its destruction.
With this knowledge, other aspects of mechanical performance can be accurately derived and through skillful engineering, one can determine:
The impact energies the part can be expected to see in its lifetime
The type of impact that will deliver that energy, and then
A material that will resist such assaults over the projected lifespan.

To Use MAX CLR-HP A/B As A Casting Resin
Clean the mold and apply a good quality release agent such as wax mold release or PVA mold release.
Slowly pour the mixed MAX CLR HP into the on the corner of the mold cavity and allow the resin to fill the cavity allowing the entrapped air bubbles to rise to the surface.
Remove any surface air bubbles using the technique described above.
Allow to cure at room temperature for 24 to 36 hours.
To use MAX CLR-HP A/B As A Clear Electrical Potting Compound
Place the circuit board in the casing or cavity and secure all wiring leads to its desired position.
Pour the mixed MAX CLR-HP into one corner of the cavity and fill to the desired level. By pouring or filling the resin from the corner of the electronic casing any air voids is pushed away and reduce the possibility of "high-pots" that is caused by voids in the potting compound.
Cure at room temperature for at least 24 hours before putting in service.
Thick Casting Applications
Mix and pour about 200 grams of Part A resin to 100 grams Curing agent per stage casting until the desired thickness is achieved. Allow 90 minutes in between staged casting or until the prior pour has cooled before pouring the next volume. No sanding is needed in-between cast.
Continue pouring, allowing a cool-down period in-between stages to prevent overheating from the exothermic reaction. Allow to cure for at least 36 hours before demolding.
