Could you recommend an epoxy resin for formulating a 2K, ambient-cure, zero-VOC, waterborne anti-corrosive primer that dries fast, has good corrosion performance, and is cost-effective?

David Dubowik David Dubowik

Traditionally, formulators of 2K, waterborne primers had to choose between low VOC and fast dry speed, a result of conventional waterborne resin limitations. Additionally, performance properties, including corrosion resistance and flexibility, were often not achieved.

Ancarez™ AR550 waterborne epoxy resin is highly recommended for formulating 2K, zero-VOC, waterborne epoxy primer coatings for metal substrates. This product—a dispersion delivered at 55% solids in water—offers performance characteristics equal or superior to coatings based on traditional solid epoxy resin dispersions, however, at zero-VOC and lower cost-in-use. Systems incorporating Ancarez AR550 resin and Anquamine® 401 curing agent yield enhanced set-to-touch dry times, early rain resistance, increased salt spray resistance and have shown increased compatibility with universal colorants.
