Vinyl Ester Resin By Unique Polymers

Our range of Vinyl Ester Resin (VER) used in the fabrication of a wide range of FRP structures by hand lay up, filament winding and other conventional fabricating techniques. Structures made with
VER possess outstanding resistance to both acids and alkalies at room and elevated temperatures besides having resistance to crazing and excellent electrical and thermal insulation properties.

Salient Features :
Vinyl Ester Resins are ester derivatives of epoxy resins combining the advantages of epoxies and polyesters.They possess higher flexibility like that of epoxy and ease of processing like that of polyesters. They also offer Superior chemical resistance to most chemicals like that of Bisphenol Polyesters.

Vinyl Ester Resins are exceptionally reactive and hence, cure rapidly resulting in good green strength.
