Fiber Glass sizing agents
GRECO fiber glass sizing agents are aqueous polyurethane dispersions based on polyester polyol and aliphatic isocyanate. It features high solid content, low viscosity, good chemical and weather resistance properties. The aqueous polyurethane resin can be applied to glass fiber surface treatment, plastic finishing, and high-strength laminated adhesion. It is particularly suitable for fiber glass sizing used in reinforced thermoplastic plastic such as polyamide.
