Abstract: The present invention provides moisture-curable compositions comprising an amino ester catalyst as an alternative to organotin catalysts. In particular, the present invention provides a condensation catalyst comprising a secondary amine, a tertiary amine, a substituted amine (e.g., an amino ester compound), or a combination of two or more thereof and optionally one or more aminosilanes or siloxanes. Further, the compositions employing amino esters allow for tuning or adjusting the cure characteristics of the compositions by the addition of other components such as adhesion promoters or acidic compounds, and provides good adhesion and storage stability.

Abstract: A coating composition is shown and described herein. The coating composition is a solvent-based silicone coating comprising a tin-free catalyst. In embodiments, the composition comprises (a) a hydroxyl terminated polydiorganosiloxane; (b) an organopolysiloxane having at least two hydrogen atoms bonded to silicon atoms in the organopolysiloxane molecule; (c) a catalyst comprising a metal carboxylate, wherein the catalyst is free of tin; (d) a solvent; (e) optionally an amino compound; (f) optionally an adhesion promotor; and (g) optionally a filler.
