CoREZYN® Polyester and Vinyl Ester Tooling Gel Coats

Polyester tooling gel coats are designed specifically for manufacturing fiberglass tools and not intended for exterior application. They offer hard, durable, scratch resistant surface with high gloss.

Vinyl ester tooling gel coats offer chemically resistant, hard, durable, scratch resistant surface with high gloss. Molds coated with vinyl ester tooling gel coats should not be exposed to ultraviolet radiation due to rapid polymer degradation resulting in a loss of gloss and discoloration of the part. These tooling gel coats are recommended for applications such as RTM where temperatures may exceed the HDT of conventional polyester tooling gel coats.
