Like
polyester resins, these are dissolved
in styrene to reduce the viscosity during fabrication into
a composite. Catalysts are required to cure the material.
No additional agents are required in order to produce high
adhesion to glass fibres. The product has more flexibility
and greater fracture toughness than a polyester resin. Heat
deflection temperatures up to 200°C can be obtained.
