Description: Unsaturated Polyester Powder Resin
General Information: COIM has developed a range of polyesters for the treatment of glass fiber. These polyesters come in powder and emulsion form and are collectively known as FILCO®. The products in the FILCO® line serve to size glass fiber, to optimize the mechanical characteristics of the fiber, or to bind the fibers for the production of mat.
Applications: Filco 657 is used as a binder in both chopped and continuous fiber glass products for the production of thermosetting glass/resin composites in low pressure molding in RTM injection or in reinforcement of polyurethane foams.
Filco 657 has good melting capacity and high heat reactivity. Drying temperatures between 170°C and 200°C at 40 - 70 seconds are recommended for application. After cross-linking, Filco 656 becomes insoluble (in styrene) and acquires its binding power.
Note: According to the customer, the peroxide content may be modified.
