Abstract

The invention relates to alkoxy-crosslinking RTV1 silicone rubber mixtures based on hydroxy-terminated polydiorganosiloxanes containing a trialkoxysilane with a substituted amidoalkyl radical, which can be prepared using conventional mixing technologies. The novel RTV1 silicone rubber mixtures cure rapidly and without tack to give products with good mechanical properties. The shelf-life of the mixtures is excellent. One particular advantage of this invention is that it is also possible to create systems in which crosslinking produces only elimination products which are completely free from toxic methanol.
