3-Isocyanatopropyl methyldimethoxysilane Description

CFS-720, 3-Isocyanatopropylmethyldimethoxysilane is a bifunctional silane combined with isocyanate functionality and alkoxy groups. It combines the functionality of an isocyanate group and an alkoxy group. The dimethoxy group of isocyanate silanes can form a reactive silanol group following hydrolysis, and then offer superior adhesion to a variety of inorganic materials. With the alkoxy group, CFS-720 can hydrolyze smoothly and compositions will be stable.

CFS-720, 3-Isocyanatopropylmethyldimethoxysilane with high functionality can easily react with active hydrogen in organic polymers. Please consult Co-Formula team if any inquiry about this made-to-order product.
