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 362 is an epoxy-resin in non ionic water emulsion
- non ionic emulsifier built in the polymer
- narrow particle size distribution
- good shelf life owing to hydrolytic resistance and fine particle size
- high mechanical shear stability to the diluted emulsion
- hydrolysis and sedimentation stability in a wide pH range
Characteristics of the dried film: - clear
- non tacky
- glass transition temperature TG " 10°C
- high thermal stability
- does not yellow at high temperature
- compatible with epoxy and all types of unsaturated polyesters
- quickly soluble in styrene
Applications: Filco 362 is suggested as a film former for glass fiber sizes for:- chopped strand for thermoplastic matrices (PBT-PC-ABS, etc.)
- filament winding roving
- pultrusion roving
- roving for translucent sheet
