Brush vinyl ester gelcoats

Hand-applied gelcoat for mould making

Crystic 15PA(B), in the catalogue's colour variants, is intended for composite moulds made with unsaturated polyester or vinyl ester resins. Brush-applied Resolcoat VI 5090, clear or pigmented, is described for vinyl ester and epoxy moulds. Selection depends on the mould resin and the process's chemical demands, not simply both products being vinyl ester.

Planning the working surface

Choose the hand-application version and prepare the pattern before coating. Sealers and release agents address porosity and mould separation; gelcoat forms the surface. If you have spray equipment and prefer that process, compare spray-applied vinyl ester gelcoats without transferring brush-application settings.
