The new, cost-effective, environmentally and processing friendly emulsifier offers easy handling by combining both characteristic external and internal emulsification phases with no additional chemical modification required.

“Solvay’s Reactsurf 0092 emulsifier incorporates a highly reactive functional cross-linking group, a perfect balance and synergy between emulsification and epoxidation to achieve a highly reactive emulsifier,” said Dr. Rong Er Lin, Research & Innovation Manager, Solvay Novecare Coatings Asia-Pacific. “This offers good particle size control for optimum emulsion coalescence and consistency without reduction in strength and provides excellent application performance and emulsion stability of paints and coatings.”

Solvay reports that waterborne epoxy emulsions that incorporate Reactsurf 0092 exhibit excellent freeze-thaw (F/T) resistance and are still flowable under -10 °C (14 °F) at up to 5 F/T cycles. Results of salt spray tests (ASTM B-117) on cold steel rolled (CRS) plates coated with epoxy emulsion paint with both high and low pigment volume concentrations (PVC) display a combination of high corrosion resistance, superior wet-adhesion, and no peel off, contrary to test benchmarks. Additional characteristics such as MEK (methylethylketone) Rub Test (ASTM D5264), impact resistance and pendulum hardness are equivalent to conventional waterborne epoxy coatings but with the significant benefit of very low VOCs.
