Using DOTLM

Dioctyltin laurylmercaptide is used in esterification and transesterification reactions. The catalyst cross-links RTV silicones, for example for technical applications, and polyurethane-based systems, such as those used in sealants or for the production of moldings. Very hydrolysis-resistant and with a long pot life, DOTLM is particularly suitable for the production of water-driven molded PU bodies, which are supposed to be elastic but still require a hard-wearing, closed surface.

Transport and Storage

Dioctyltin laurylmercaptide is shipped in canisters made of polyethylene and has a minimum shelf life of 6 months when the original packaging is closed, without any loss of quality.
