The material, processing and mould temperature must be from 18 to 25°C. After mixing the two components it is easily possible to incorporate additives if necessary. Biresin® LS is applied quickly and easily due to its low viscosity. It will easily wet out fibres and incorporate high levels of fillers and powders with high binding force. The ratio between resin and selected fibre must be determined and reliably controlled. For laminates glass fibres with binding twill are better than binding cloth because of its better suppleness. It is adviced to lay up a balanced laminate to avoid distortion when...
