It has excellent hardness, is resistant to the aggression of styrene and is recommended when you want to obtain a particularly bright appearance. The mould must not be put into service before the gelcoat has reached a hardness index of at least 35 barcol. The minimum temperature during treatment and after treatment should be at least 18°C.


The gelcoat for mould is pre-accelerated and thixotropic.
