Silane Coupling Agent Crosile550 Aminopropyltriethoxysilane
Chemical Properties
Censil 550 Silane is gamma-aminopropyltriethoxysilane. Acts as a coupling agent and adhesion promoter.
Censil 550 is a versatile amino-functional silane coupling agent used over a broad range of applications to provide superior bonds between inorganic substrates and organic polymers. Enhances the flexural, compressive and interlaminar shear strengths before and after exposure to humidity and greatly improves wet electrical properties.
As a phenolic resin binder additive, it can impart moisture resistance and allow recovery after compression. It is compatible with thermoplastics, polyamides, polyesters, polycarbonates, epoxies, polybutylene terephthalate and thermoset. Silane Crosile®550 is used in glass fiber.
