Abstract

Curable compositions which can be stored under anhydrous conditions, but when exposed to atmospheric moisture cross-link to form elastomers, which consists of (1) a diorganopolysiloxane having terminal condensable groups, (2) a silicon compound containing at least three hydrolyzable groups per molecule in which the hydrolyzable groups are amino groups bonded to silicon via nitrogen and/or oxime groups bonded to silicon via oxygen and (3) at least one additional component which improves adhesion of the elastomers obtained from said compositions to substrates, in which the additional component (3) is an organosilicon compound containing at least one siloxane-oxygen atom and at least one amino group which is bonded to silicon by carbon.
