FILCO® 662 is a bisphenolic, unsaturated polyester resin in powder form
- Very high molecular weight
- Very quickly soluble in styrene
- Very high binding power for glass fibers in "hot melt" operating conditions
- High degree of compatibility with unsaturated polyester matrices.
Applications & Uses
- Compatible Polymers & Resins
- Applications
FILCO® 662 main application
- Styrene soluble binder for chopped strand mat and continous filament mat
- Binder for preform.
- Processing Information
2.5 - 5% of FILCO® 662 on the glass weight is normally required according to the weight for square meter and stiffness wanted for glass mat. Water as fine mist is sprayed to help FILCO® 662 to stick to glass fibers. After application of FILCO® 662 the glass mat is stoved at 180 - 210 °C for 1 - 2 minutes. The operation lets water evaporate and melt FILCO® 662, which accumulates at the contact points of the glass strands, binding them.
