MAX CLR-TC A/B is a two-part epoxy-based system specially formulated as topcoat system.
It offers surface durability performance while maintaining crystal clarity, gloss, and other aesthetic qualities.
MAX CLR-TC also offers high chemical resistance, excellent coating adhesion and overall durability suitable for many aspects of an aesthetic and protective coating for many applications. MAX CLR-TC A/B demonstrates excellent wetting and adhesion to a variety of substrates such as composite materials, concrete and ceramic products, plastics, wood, glass, steel, aluminum and most soft metals. It's cured high gloss finish, excellent transparent clarity, and ease of use make MAX CLR-TC an excellent choice as high-quality coating system for composite laminates, protective coatings, and applications where a very smooth and high gloss finish is desired.
MAX CLR-TC A/B is 100% solids and does not contain Ozone Depleting Chemicals (ODC), non-reactive plasticizers or solvent fillers.
THIS KIT INCLUDES A SET OF YORKER CAPS FOR CONTROLLED DISPENSING.
Use these Yorker caps to dispense the material with ease and minimize over pouring and reduce spills.
We do not recommend using dispensing pumps. The curing agent or PART B of any epoxy resin system is sensitive to moisture and carbon dioxide, which will react with the curing agent and form carbamate crystals (salt-like crystals that form on the tip of the pump) and reduce reactivity.
CARBAMATE CRYSTALS THAT FORM ON THE PUMP WHEN THE CURING AGENT IS EXPOSED AMBIENT MOISTURE AND CARBON DIOXIDE. THESE CRYSTALS ARE INSOLUBLE IN EPOXY RESIN RESULTING IN CONTAMINATION AND CAUSES POOR CURE AND AMINE-BLUSHING.
Use these Yorker caps and cut the tip to meter the orifice of the of the tip for accurate dispensing.
When done, just replace the tip cap and it will exclude ambient moisture and air and keep the resin system viable for years.
To use the caps, cut off the tip to the desired hole size, and attach, do not cut pass the ridgeline that keeps the tip cap in place.
To dispense, lay the plastic jug unto its side and apply pressure on the bottle to dispense the contents.
When done replace the tip cap and the container is sealed and it will be usable for years.
We highly recommend using a scale to measure each component accurately.
Surface Preparation Is Key For Any Coating Application
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 so the applied epoxy is in direct contact with the base substrate.
Applying a coating over oil-based stain should be avoided if possible.

Common Problems Of Epoxy Based Top Coats
POOR SURFACE WETTING
Due to the coating’s inability to overcome the LOW SURFACE ENERGY (LSE) or wettability of the substrate,
the coating agglomerates and fails to create a continuous laminar film.
It is random and an irregular surface pattern is very common to the texture of an orange peel hence the namesake.
It is predominantly caused by poor substrate wetting and leveling of the coating.
Other influences of this surface texture are the mirrored roughness of the substrate
Rather than being flat and smooth, the surface takes on the appearance of an orange peel,
Its high gloss finish, excellent transparent clarity, color stability and ease of use make MAX CLR-TC an excellent choice as a top coatings applications.
MAX CLR-TC also offers high chemical resistance, structural adhesion and overall durability suitable for many protective coatings applications.

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.
