Methyltriacetoxy silane

PI, the acetoxy end capped Dexsil polymer, reacts on exposure to moisture to form acetic acid and silanol end groups which self condense. The coatings were not transparent because some crystallization occurred before cure was completed. To correct for this, a highly functionalized coating was synthesized by reaction of methyltriacetoxy silane and 1,7 bis(hydroxydimethylsilyl)—m earborane which produced a prepolymer with one acetoxy crosslinking site per repeat (Scheme 1). 

In one component RTV systems the cure can result by methyltriacetoxy-silane reacting with moisture with tin soaps added to control the cure rate. These resins were used for adhesive and sealant applications [32].
