Andisil® VOS by AB Specialty Silicones is a crosslinking agent. It is a liquid raw material used for neutral condensation curing silicone sealants. In the presence of a (tin) catalyst, this silane react with hydroxy-functional silicone polymers. Its exposure to moisture results in the formation of crosslinked, elastomeric silicones. In contrast to acidic or basic curing systems, no acidic acid or amine, but 2-butanone oxime is liberated during application. Due to the neutral character of 2-butanone oxime, sealants based on Andisil® VOS can be applied even on (corrosion) sensitive substrates like metals or marble. It has a shelf life of 1 year.
