Abstract

A noncurable sealing material from a hydroxyl end-blocked polydiorganosiloxane, a filler and a silane or siloxane with two hydrolyzable groups having silicon-nitrogen bonds or silicon-oxygen-nitrogen bonds. The material when mixed and stored under substantially anhydrous conditions remains fluid but when exposed to the moisture in air increases in viscosity to form a sealing material which is uncured.
