Countertype of DowCorning Z-6194, ShinEtsu KBM-22, Wacker M2-DIMETHOXY


Chemical Structure


Introduction

SiSiB® organosilanes basic structure is RnSi(OR)4-n, wherein "R" is an alkyl, aryl, or other organofunctional group and "OR" is a methoxy, ethoxy, or acetoxy group. SiSiB® PC5221 is a monomeric alkylalkoxysilane. It hydrolyzes in contact with water, releasing methanol, to form highly reactive silanols, which further condense to form oligomeric and polymeric siloxanes.
