Crystic Gelcoat 14PA is designed for use in the manufacture of high quality, FRP composite tooling. It is a pre-accelerated brush gelcoat specially formulated from a vinyl ester base resin and is available in a restricted range of colours. The information contained in this leaflet also applies to pigmented versions. Features and Benefits Crystic Gelcoat 14PA is heat resistant with high impact strength and good resistance to chemical attack. It is extremely resilient and can be polished to a high gloss.
Application Crystic Gelcoat 14PA is a tooling gelcoat and the application should be controlled at 0.4 - 0.6 mm wet film thickness. As a guide, approximately 500 - 750 gm-Â² of gelcoat (depending on pigment) will give the required thickness when evenly applied. If left for prolonged periods, Crystic Gelcoat 14PA will cure to an almost tack-free finish, but this has no adverse effect on the adhesion of the backing laminate. Crystic Gelcoat 14PA requires only the addition of catalyst to start the curing reaction. The recommended catalyst is Butanox M50 (or other equivalent catalyst), which should be added at 2% into the gelcoat.

What is the heat deflection temperature of the tooling Gelcoat?
On a fully cured Gelcoat this is 106 degrees C.
What is the post curing schedule of 15 PA?
For optimum life of the Gelcoat a mould constructed using Crystic Gelcoat 15PA (B) should be fully cured before being put into use. This can be achieved by placing the mould in an oven at 40 ÂºC for 30 hours. If this is not practical, the mould should be left in warm conditions (20 ÂºC) for 2 â€“ 3 weeks prior to use, as high residual styrene content might encourage stick ups. Where a mould is likely to experience elevated temperatures during cycling (eg due to high exotherm temperatures within backing laminates), it should be post cured at a temperature in excess of the cycling temperature.
