Introduction :
The durability of the composite moulding is highly dependent on the quality of its exposed surface. The Gelcoat is the face of the composite moulding as it provides both protection and surface aesthetics
Gelcoat can be applied by brush or spray, though developments in gelcoat technology and spray equipment have combined to markedly increase the use of spray application methods.
Crystic® Gelcoats :
Whichever application method is chosen, it is important to choose a good Gelcoat, specially formulated with correct rheology for both brush and spray application.
Crystic® Gelcoats are formulated to provide superior long term performance derived from 50 years of reliability, experience and innovation.
Latest technology gelcoats include very low colour change, market leading Crystic® Permabright, ultra low styrene emission Crystic® Ecogel and Crystic® Fireguard intumescent topcoats, designed to protect composites from fire.
Crystic® Gelcoats are used for application such as marine, land transport and construction.
Weathering :
When gelcoated laminates are used indoors, durable and decorative mouldings are easily achieved.
For exterior applications, problems with discoloration, fading, loss of gloss may be encountered if the gelcoat is not specifically designed for the application.
12 months tests at Florida
Crystic® gelcoats and 18 base pigments have been thoroughly tested and qualified by subjecting them to 12 months in intense sunlight of Florida, QUV and Xenon weathering tests. In addition Crystic® gelcoats are subjected to 1 year osmosis and blistering tests before qualifying for application such as marine.

Monsoons and Gelling Problems – help yourself!
The monsoons will be here soon, and gelling problems and gel-time issues are not far away. A little knowledge can help you get to the root of the problem yourself. If you are aware of the curing mechanism and approach the gel-time problem equipped with the correct knowledge, you won’t have any of these seasonal problems at all.
