Waterborne Epoxy Resins

EPI-REZ™ waterborne epoxy resins, when properly formulated, perform at levels consistent with solvent-borne technologies while reducing VOCs, which enhances worker safety. EPI-REZ epoxy resins are easily adjusted with water, making these systems highly adaptable. Water-based wetting agents, additives, co-solvents and coupling agents can be added easily to speed drying, enhance corrosion resistance, increase adhesion, and extend pot life.

Westlake Epoxy's waterborne epoxies are suitable for both traditional and specialty applications. These include:

Coatings: metal primers for protective and transportation applications
Civil engineering: floor primers, top coats, self-leveling coatings, grouts and sealants
Adhesives: tie-coats, primers and laminates
Composites: Wind Energy, Automotive and Aerospace
Fiber sizing: glass, synthetic and carbon fibers
Textiles: saturants, binders and back coatings
Electrical: insulating materials
