FILCO® 661MF008

1 of 141 products in this brand
FILCO® 661MF008 stands as a bisphenolic, unsaturated polyester resin in a convenient powder form, characterized by its very high molecular weight, rapid solubility in styrene, and remarkably high binding power for glass fibers, particularly in "hot melt" operating conditions. This resin exhibits a notable compatibility with unsaturated polyester matrices, ensuring seamless integration into composite systems. With the ability to produce a specific type of mat, FILCO 661 MF008 is a versatile and efficient material for manufacturing composite products, offering a comprehensive solution for a range of applications.

Processing Information

2.5 - 5% of FILCO® 661MF008 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® 661MF008 to stick to glass fibers. After application of FILCO® 661MF008 the glass mat is stoved at 180 - 210 °C for 1 - 2 minutes. The operation lets water evaporate and melt FILCO® 661MF008, which accumulates at the contact points of the glass strands, binding
