Storage stable, one part polyorganosiloxane compositions.

摘要

A specified group of monoalkylamines and alkylenediamines wherein the alkyl or alkylene group contains from two to four carbon atoms imparts long term storage stability at temperatures of up to 40 DEG C to one part polyorganosiloxane compositions curable by a platinum catalyzed hydrosilation reaction. The inhibitors do not interfere with the ability of these compositions to cure rapidly at temperatures of 135 DEG C to form gels that are useful encapsulating materials for delicate devices, including electronic circuits.
