Epoxy.com Product #663 Vinyl Ester Coating is a 100% reactive, vinyl ester
novolac used to coat concrete or steel surfaces in chemically aggressive
industrial environments. Due to its high molecular weight and low permeability,
it will withstand exposure to a broad range of acids, caustics, and
solvents.Epoxy.com Product #663 Vinyl Ester Coating is designed for coating
primary and secondary containment, trenches, troughs, pump pads, equipment, and
structural members. Low temperature accelerators are available for positive
cures at temperatures from 32° to 55°F.
- Excellent resistance to a wide range of chemicals.
- High temperature performance; in many cases up to 350°F (spills) or 400°F (dry
- Application by conventional painting techniques.
- Best overall performance coating for secondary containment.
- Self-extinguishing in thin films.
- Substrate temperature must be a minimum of 50°F.
- Substrate must be free of dirt, waxes, curing agents, and other foreign materials.
- Substrate must be completely dry.
- Requires skilled installers to assure successful results.
Two-component peroxide cured vinyl ester novolac.
Surface Preparation is the most critical portion of any successful resinous
flooring system application. All substrates must be properly prepared as
outlined in Epoxy.com Surface Preparation
Recommendations. Contact Epoxy.com Technical Support with any questions.
Observe all precautions on MSDS and label when using this product. Mix 3-4 oz.
Part B per gallon with Part A with a low speed drill for at least two (2)
minutes. For spray application, add up to 1 quart Styrene per mixed gallon, if
needed. Apply by roller, brush, or spray. Use a nylon or natural bristle brush
or a good quality medium nap roller. Can be sprayed with airless or conventional
Clean skin with soap and water; use MEK, xylene, or clean proprietary epoxy
thinners for equipment.
160 square feet per gallon yields 8 mils DFT due to shrinkage during cure. Two
coats are recommended for general service.
Epoxy.com Product #663 Vinyl Ester Coating is available in #150 Dark Grey and Custom Colors as approved.
