Tooling & Vacuum Bagging Processing

Gelcoats
The first materials marketed as protective coatings for composites were pre-formulated, compounded products called gelcoats, which are used as ‘in-mould’ coatings. Today, this has become a highly specialized business involving colour technology, air release requirements, thick film build-up and rapid cure times to produce in-mould finished surfaces with excellent gloss, colour and surface integrity retention after years of environmental exposure.  Gelcoats are available in brush and spray versions and are best put down at a thickness of 0.5mm (approximately 500 g/m²). If they are too thin, poor cure occurs and fibre pattern will result. If they are too thick, crazing and cracking can occur and the laminate will be more susceptible to reverse impact, star cracking damage.
