Abstract
Abstract The curable compound of the invention is used as a two-part or many-part curable compound, and water or a hydrated metal salt is added to the curing agent containing a silanol condensation catalyst. Thus, the compound of the invention is a curable compound comprising at least two components: (A) a main ingredient which contains a saturated hydrocarbon polymer containing silicon-containing groups which have hydrolyzable groups bonded to the silicon atom and which are crosslinkable by forming siloxane bonds, and (B) a curing agent containing a silanol condensation catalyst and water or a hydrated metal salt.
