Open Mould
Crystic resin compounds and gelcoats have been developed to meet the requirements of hand lay-up and spray applications. Our products have been formulated for ease of use and good fibre wet-out. Our resins are available in a range of viscosities, gel times and peak exotherms to suit all types of applications.

Hand lay-up
Chopped strand mat is the reinforcement most commonly used in contact moulding, though the use of woven roving and various combination materials has grown considerably over the last few years.

Once the gelcoat has cured sufficiently a liberal coat of resin is applied as evenly as possible. The first layer of glass is then pressed firmly into place and consolidated using a brush or roller. Further layers of glass and resin are then applied.

Spray Lay-up
This technique involves the use of a spray gun for the simultaneous deposition of chopped glass and catalysed resin onto the surface of a mould.

A chopper unit attached to the spray gun chops glass rovings into specified lengths (usually between 20mm and 50mm), and the chopped strands are then directed towards a stream of catalysed resin and it exits the spray gun.

Resins, such as those in the Crystic range, which are designed for spray application are generally low in viscosity, so they rapidly wet out the chopped strands. This ensures they are more easily atomised into the desired spray pattern. The rapid wet-out achieved by spray deposition allows faster and easier consolidation than would be achieved with hand- lay methods, but thorough rolling of the laminate is still necessary to ensure complete air removal.

New Mould Protection Overcoating Product for 2007:
Crystic Mouldguard^®, an easy to apply removable overcoating, specially designed to protect composite or steel moulds when they are not being used in production. Crystic Mouldguard^® helps save manufacturers significant amounts of time and money as moulds can be back in production in 1/10^th of the time it would take if they had not been protected.
