Description: Film Former for Glass Fiber Sizes 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. Typical Physical and Chemical Characteristics: Filco 339 is an unsaturated polyester-epoxy polymer in non-ionic water emulsion Characteristics of the dried film: - clear
- not tacky
- compatible with unsaturated polyester and epoxy resins
- very quickly soluble in styrene
Applications: Filco 339 is suggested as a film former for glass fiber sizes for:- roving for translucent sheet
- spray roving
- mat roving
Fiber glass sized with Filco 339 present high impregnation speed during glass resin composite high transparency. Information provided by P.A.T. Products, Inc. |
