EPI-REZ™ Resin WD-512


EPI-REZ Resin WD-512 water dispersible resin is a liquid epoxy resin that is specifically designed for convenient water dilution. Water dilution under agitation forms a fine particle dispersion of liquid epoxy resin in water. This dilution can be accomplished at all solids levels to meet the desired viscosity and handling characteristic. EPI-REZ Resin WD-512 is particularly attractive for two-package high solids water-based formulations. It can also be used in highly crosslinked onepackage baked formulations. Typical end uses include modifiers for Portland Cement, concrete, mortars, stuccos, grouts, as a binder for trowel applied floor toppings, as bond coats, base coats, membrane coatings, sealers, and in two-package adhesives.
