Introducing highly chemically resistant Novolac epoxy wall coating. Bring your chemical resistance to new heights. Apply this Novolac Epoxy Wall Coating on walls in thicker coats, with less runs. Same great chemical resistant Novolac Epoxy as Product #633, but thicker.
Description
Epoxy.com Product #633W is a 100% solids epoxy novolac coating ideal for harsh chemical and solvent environments. “W” designates High Viscosity formulation for improved film build on vertical surfaces. Epoxy #633W can be used as a seal coat for various Epoxy.com products and systems where extreme chemical resistant performance is required, such as secondary containment, solvent storage, pump pads, trenches, chemical process areas, and other high exposure areas.
Epoxy Novolac Wall Coating is 100% solids, modified amine adduct cured epoxy novolac (novolac epoxy) resin.
Advantages
- Exhibits excellent resistance to strong acids, alkalis, and most industrial chemicals and solvents.
- Can be applied in occupied facilities.
- Can be applied in cool damp conditions.
- Can be rapidly re-coated in ambient conditions.
Considerations
Good surface preparation is one of the most important parts of the installation of a high end coating. Be sure to follow our
Surface Preparation Guide before installing this product.
Installation
- Review and follow epoxy installation tips
- Properly prepare the substrate.
- Mix small batches of the material with 2 parts “A” and one part “B”, being sure to completely mix for 3 min. Mix only what you can use in half the potlife. Remember the bigger the batch the faster it will setup in your bucket
