EPIKURE™ Curing Agent 6870-W-53



Product Description

EPIKURE Curing Agent 6870-W-53 is a 53% solids, non-ionic aqueous dispersion of a modified polyamine adduct curing agent. This high molecular weight curing agent contains no solvents and is designed to provide the high performance of traditional epoxy coatings in low VOC1, non-HAPS2 waterborne epoxy coatings. Although EPIKURE Curing Agent 6870-W-53 exhibits good compatibility with other epoxy resin dispersions, it is designed for use with

EPI-REZ™ Resin 6520-WH-53.

1 VOC is the acronym for volatile organic compound, as defined by the U.S. 40CFR51.100 (s).

2 HAP is the acronym for hazardous air pollutant, as defined by the U.S. Clean Air Act Amendments of 1990.

General Information

The preferred resin choice for optimum performance over a wide range of stoichiometries is EPI-REZ Resin 6520-WH-53. This versatile binder system (6520-WH-53/6870-W-53) allows clear coats, enamels and primers to be formulated with volumetric mix ratios from 4:1 to 1:1. EPIKURE Curing Agent 6870-W-53 is also compatible with many other waterborne epoxy resin dispersions and additives.
