New Waterborne Epoxy Resin Dispersion : For Low-VOC, 2K High-PerFormance Metal Primers Without Anti-Corrosion Pigments

摘要

Solventborne, 2-pack (2K) epoxy-amine coating systems have been commonly used to formulate high-performance metal primers. Crosslinkable at ambient temperatures, they provide excellent adhesion as well as corrosion protection to many metallic substrates. However, due to new, lowered VOC limits enacted in certain areas as well as other proposed regulation changes in North America and Europe, there is a need to reduce VOC by shifting to waterborne 2K epoxy systems.
