This Polyester Resin 10kg is a high-quality, solvent-based resin that is used as a base coat in conjunction with GRP fibreglass matting for flat or sloping roofing applications. It is also suitable for general-purpose fiberglass applications and repair work.

Key Features:

  • Low Styrene Emission: This resin has very low styrene emission, which means that it is less harmful to the environment and to the workers who are using it.

  • Improved Water Resistance: This resin is designed to be highly water-resistant, making it ideal for use in roofing applications.

  • Low Viscosity: This resin has a low viscosity, which makes it easy to apply and ensures that the fiberglass matting is properly wet out.

  • Long Pot Life: This resin has a long pot life, which gives you plenty of time to work with it before it starts to cure.

  • Lower Exotherm: This resin has a lower exotherm than some other resins, which means that it is less likely to warp or bubble when it cures.
