A gel coat is the first layer of resin applied to the prepared mould, it forms the finish of one of the surface laminations, providing protection against chemicals, weathering, moisture or any aggression from the environment.

Chemically, gels coats are thermosetting resins with pigments and additives in suspension which allow its application to the mould surface, even in vertical walls without sagging.

Generally they have greater abrasion resistance and corrosion resistance, as well to the UV radiation and to temperature changes than their base resins.

They shall be applied with a consumption of 600 g/m2 for parts and a maximum of 1 kg/m2 for moulds.
