Fibreglass Supplies 300g Powder-Bound Epoxy-Compatible Chopped Strand Matting is a lightweight fibreglass reinforcement material manufactured from randomly distributed chopped strands of E-glass. Its powder-bound construction makes it compatible with epoxy, polyester and vinyl ester resin systems, giving you a versatile reinforcement for boat building, flat roofing, mould making, GRP repairs and general laminating projects.
Suitable for use with normal hand lay-up techniques, this 300g chopped strand mat provides fast resin wet-through and wet-out alongside good air-release properties. Its effective resin absorption helps create a consistent laminate while making it easier to remove trapped air during application.
The lightweight mat is soft to handle and conforms closely to curves, corners and complicated mould shapes. It is easier to shape than heavier 450g and 600g matting, making it particularly suitable for detailed moulds, intricate components and applications where a lighter reinforcement layer is required. It can also be used with compatible high-temperature mould-making systems.
