Polyester gel coats create a smooth, high-quality surface layer inside molds. They offer strong resistance to abrasion, acids, and oils, protecting the final part. Transparent gel coats can be easily tinted with Polyester Pigments for custom colors and finishes.
Gelcoat is a material used to provide a high-quality finish on the visible surface of a fiber re-nfordcomposite The most common gelcoats are thermosetting polymers based on epoxy or unsaturated polyester resin chemistry. Gelcoats are modified resins which are applied to moulds in the liquid state. They are cured to form crosslinked polymers and are subsequently backed with thermoset polymer matrix composites, which are often mixtures of polyester resin and fiberglass, or epoxy resin, which is most commonly used with carbon fibre for higher specific strength
