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. It is the equivalent of Momentive's A-Link 25, Wacker's GF41, ShinEtsu's KBE-9007 silane.
Color and Appearance
Colorless transparent liquid
SiSiB® PC2710 and SiSiB® PC2720 can be used as silane crosslinking agent 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® PC2720 hydrolyzes slower than SiSiB® PC2710. SiSiB® PC2720 is better for applications requring greater open time or enhanced shelf stability.
SiSiB® PC2710 and SiSiB® PC2720 can be used as adhesion promoters for silicone coatings or sealants, 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 is supplied in 20Kg plastic drum, 190Kg steel drum or 950Kg IBC container.
In the unopened container SiSiB® PC2720 has a shelf life of one year.
