Solvay launches reactive water-based emulsifier for solid epoxy resins

Solvay has developed Reactsurf® 0092, a non-ionic reactive water-based emulsifier without alkylphenol ethoxylates (APE) for solid epoxy resins, industrial coatings and paints or adhesives
.

Solvay’s unique multifunctional Reactsurf® 0092 technology enables the formulation of high-performance waterborne epoxy coatings that rival or exceed solvent-borne (SB) coatings, but with less volatile organic compounds (VOCs).
content was significantly reduced
.
Solvay is continually developing and delivering products to meet the sustainability challenges and regulatory requirements its customers face today and tomorrow, resulting in cleaner, healthier paint and coatings formulations
.

This novel, cost-effective, environmentally and process-friendly emulsifier offers facile operation without the need for additional chemical modification by combining the features of external and internal emulsification stages
.

"Solvay's Reactsurf® 0092 emulsifier incorporates highly reactive functional cross-linking groups, providing a perfect balance between emulsification and epoxidation," said Dr.
Rong Er Lin, Research and Innovation Manager, Coatings Asia Pacific, Solvay Novecare Balanced and synergistic action, resulting in a highly active emulsifier
.
This provides good particle size control for optimal emulsion coagulation and consistency without loss of strength, and provides excellent application properties for paints and coatings and Emulsion stability

Waterborne epoxy resin emulsions containing Solvay Reactsurf® 0092 exhibit excellent freeze-thaw (F/T) resistance after up to 5 freeze/thaw cycles at -10°C (14°F).

.
Salt spray test (ASTM B-117) results of cold rolled steel (CRS) panels coated with high and low pigment volume concentration epoxy latex paints show that, contrary to the test benchmark, Solvay Reactsurf® 0092 waterborne epoxy The resin emulsion has a combination of high corrosion resistance, excellent wet tack and no peeling
.
Other properties such as MEK (methyl ethyl ketone) rub test (ASTM D5264), impact resistance and pendulum hardness are comparable to traditional waterborne epoxy coatings, but with the significant advantage of very low VOCs
.

Epoxy latex paints containing Solvay Reactsurf® 0092 and high pigment volume concentrations showed better corrosion resistance after a 500-hour salt spray test (ASTM B-117) on cold rolled steel sheets
.

High-performance waterborne epoxy paints and coatings are used in a wide variety of end-use industrial applications such as rail freight and passenger vehicles, rails and fittings, storage tanks, shipping containers, pipelines and steel works
