BEST PAINT FOR ANY
AUTOMOTIVE NEED

CHEMICAL BASIS

Top Paints Fibreglass Resin is a pre-accelerated, rigid polyester resin designed for the manufacture of good colour laminates or casting.

FEATURES

• Low viscosity
• Fast curing
• Good colour
• Low exotherm

BENEFITS

• High filler loading
• Reasonable production rates
• Readily pigmentable
• Suitable for construction of thick laminates or castings

CURING CHARACTERISTICS

Top Paints’ Fibreglass Resin needs only the addition of catalyst to start the curing reaction. The resin should be allowed to
attain workshop temperature (23°C) before being formulated for use. The correct amount of catalyst is therefore added and thoroughly stirred into the resin shortly before use. The ambient temperature and the amount of catalyst control the geltime of the resin formulation. Curing should not be carried out at temperatures below 15°C. Ideally, the catalyst level should range between 1 and 2 phr.

POST CURING

Satisfactory laminates and castings for many applications can be made from Top Paints’ Fiibreglass Resin by curing at ambient temperature (but not less than 15°C). When optimum properties and long-term performance are required however, the laminates and castings should be post cured After release from the mould, laminates and castings should be allowed to mature for 24 hours at workshop temperature (23°C). They shoud then be post-cured for 3 hours at 80°C, although a longer period at a lower temperature will give almost the same result. The post-cure is most effective if it is carried out immediately after the 24 hour maturing period. Dual Purpose Casting & Fibreglass Resin

PIGMENTS AND FILLERS

Top Paints’ Fibreglass Resin may be pigmented by the addition of up to 5% POLYCHROME PIGMENT PASTE, but lower
quantities consistent with achieving adequate hiding power are preferred if the physical properties of the laminates and
castings are to be maintained. The addition of fillers to Top Paints’ Fibreglass Resin is likely to change the hardening
characteristics of the resin and will affect the properties of the laminates and castings.

STORAGE AND HANDLING

To ensure maximum stability and maintain optimum properties, polyester resin should be stored in closed containers,
maintained below 25°C and away from heat sources and sunlight. All storage should conform to local fire and building
codes. Drum stock shoud be kept to a reasonable minimum with first-in, first-out stock rotation. Where bung-in-head containers are stored outside, it is recommended that these be stored in a horizontal position to avoid the ingress of water.
