SiSiB® PC2720

3-isocyanatepropyltrimethoxysilane.
Synonym: Trimethoxy(3-isocyanatopropyl)silane

Chemical Structure


Introduction

SiSiB® PC2720 is an isocyanate functional silane. It is used for the functionalization of numerous compounds with active hydrogen atoms. SiSiB® PC2720 hydrolyzes in the presence of moisture to form silanols, which can react with themselves to produce siloxanes.

Applications

SiSiB® PC2710 and SiSiB® PC2720 can be used as crosslinkers for one part moisture curable urethane adhesives, sealants and coatings.

SiSiB® PC2710 and SiSiB® PC2720 can be used as adhesion promoters for one part moisture curable and two part reactive urethane systems.

SiSiB® PC2710 and SiSiB® PC2720 can be used as adhesion promoters for silicone sealants or coatings, to enhance adhesion to organic substrates with active hydrogen atoms.

SiSiB® PC2710 and SiSiB® PC2720 can provide good wet adhesion to glass, metal and other inorganic substrates, and can provide good thermal, chemical and UV stable performance.

SiSiB® PC2720 hydrolyzes slower than SiSiB® PC2710, SiSiB® PC2720 is better for applications requring greater open time or enhanced shelf stability.
