EPOXY GEL COAT GCC / GCI
Epoxy gel coat Coloured or Translucent

GCC are White, Black or in various European RAL colours
GCI are Translucent with Standard or Rapid curing

In order to protect the laminate, or give a coloured shiny finish, a gel coat can be applied in a mould before laminating with an epoxy system. In this instance, after the application of a release agent, a thin layer of 500 - 800 µ (400 - 600 g/m²) of gel coat should be applied with a brush. As soon as gel coat passes the gel time, and whilst still tacky, a first layer of light fabric or chopped strand mat impregnated with epoxy should be laid onto the gel coat in order to achieve the best chemical bonding with the laminate

Most problems that occur are in relation to moisture and temperature, or if the gel coat has been applied with a gun and a solvent added. Because of this we recommend that users take care of three parameters when choosing this technology:

Moisture 65 % max / Temperature of products, mould and plant between 15 & 30°C/ and maximum ventilation.

Caution : Coloured gel coat can not be produced by adding colours to the translucent product.

To produce the mould, epoxy gel coats are recommended, refer to our HRT 120 & HRT 140 Tooling Epoxy Gel coat.

It is very important to respect the following ratios between resin and hardener
