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.
