Latent tin catalyst containing polyorganosiloxane composition curable to a thin layer.

摘要

A polyorganosiloxane composition containing a tin catalyst and crosslinkable as a thin layer, comprising:… A.- a polydiorganosiloxane with silanol ends,… B.- a polydiorganohydrosiloxane,… C.- a latent tin catalyst of formula: …… …The composition may be solvent-free, in solution in an organic solvent or in aqueous emulsion. It is crosslinked by heating to a temperature at least equal to the decomposition temperature of the latent catalyst and is useful in particular for paper coating.
