FILCO® 366/1 serves as a film former within the chemical family of polyesters, particularly unsaturated polyester (UPE). Notably, it demonstrates slow solubility in styrene, contributing to the superior surface appearance of composite materials when applied. This characteristic makes it suitable for applications where achieving an enhanced surface finish is essential.
