Gelcoat or gel coat is a material used to provide a high-quality finish on the visible surface of a fibre-reinforced composite. 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.
The gelcoat (a smooth, hard polyester resin coating) is applied to the mould surface and is given time to cure before re-applying. Usually two coats of gelcoat are used.
