FILCO® 7605 is an urethanized epoxy resin available in a non-ionic water emulsion, presenting as a milky liquid. It is recommended as a film for glass fiber sizes in applications such as SMC roving and chopped strands for BMC. The resin exhibits several advantageous material features, including good non-yellowing properties, a favorable surface finish, excellent thermal stability, high hardness, and non-flammability.

Functions: Film Former
