EPI-REZ Resin WD-510 is a liquid, bisphenol A type epoxy resin specifically designed for water dilution. In combination with epoxy curing agents and dilution with water it forms resin in water emulsions. It is useful as a modifier for Portland Cement, concrete, mortars, stuccos, and grouts. As a binder it is useful for trowel applied floor toppings, bond coats, base coats, membranecoatings and sealers. EPI-REZ WD-510 forms uniform dispersions in water in combination with Aliphatic amine curing agents, including adducts, amidoamines, polyamides, and accelerated amines. To make these dispersions the EPI-REZ WD-510 and curing agent must first be thoroughly blended. Then water is added to the blend and stirred in, either manually or with an agitator powered by a motor. Resin/curing agent blends are diluted with water to a solids level of 40 to 80 percent by weight. This dispersion process is typically facilitated with glycol ether cosolvents and epoxy viscosity reducing modifiers. While batches of the water dispersed system exhibit long dispersion life (generally remain emulsified through gelation), the usable working life of some formulations is shorter than the dispersion life. The actual usable working life of a specific formulation should be determined in a laboratory by studying performance related properties as a function of time elapsed from mixing to application. EPI-REZ WD-510 can also be com-bined with ECO-CRYL Acrylic Resin Dispersion 9790 to produce two-package water reducible coatings. EPI-REZ WD-510 may be used in place of EPON Resin 828 for lower VOC's in combi-nation with waterborne EPI-CURE Epoxy Curing Agents for 2 package epoxy industrial finishes. |
