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 309 is an epoxy resin in non-ionic water emulsion
- pure epoxy resin
- epoxy equivalent ~240
- narrow particle size distribution
- hydrolysis and sedimentation stability from pH 2 to 12 min. 48 h
- good shelf life
- high mechanical shear stability of the diluted emulsion
Characteristics of the dried film: - clear
- tacky film
- compatible with unsaturated polyester, epoxy, phenolic matrices
- quickly soluble in styrene
Applications: Filco 309 is suggested as a film former for glass fiber sizes for: - filament winding roving
- pultrusion roving
- woven roving
