Vinyl Ester Novolac Binder
Epoxy.com Product VINYL ESTER BINDER is a clear, 100% reactive, vinyl ester novolac used to coat or line concrete or
steel surfaces in chemically aggressive industrial environments. It is used for coating primary and
secondary containment, trenches, troughs, pump pads, and equipment.
- Excellent resistance to a wide range of chemicals.
- High temperature performance; in many cases up to 350°F (spills) or 400°F (dry heat).
- 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 Guide
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 spray.
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, as a coating.
Epoxy.com Vinyl Ester Binder is available in Clear.
