In this study, preparation of thin films (~100μm) of condensation-curing silicones isinvestigated. It isfoundthat behavior of typicalcondensation curing system consisting of OH terminated poly(dimethylsiloxane) (OH-PDMS), tin catalyst and methyltrimethoxysilane (MTMS) or tetraethoxysilane(TEOS)cross-linker ishighly dependent on the sample thickness. High volatility of the cross-linkersthatbecomes enhanced with decreasing sample thicknessisreported. The high volatility does not allowed for proper curing of thin silicone films, even though the cross-linker is used in excess. In addition, reliability and reproducibility of such system becomes an issue.
