摘要:
Disclosed is a curable composition having good storage stability which enables to obtain a cured product wherein surface tackiness after curing is almost eliminated within a short time. A cured product of such a curable composition hardly suffer from surface dirt over a long time. No crack or discoloration occurs in the surface of such a cured product even when it is used outdoors for a long time. Specifically disclosed is a curable composition containing a vinyl polymer (A) having at least one crosslinkable silyl group and a photopolymerization initiator (B).
摘要:
A curable composition. The composition contains(A) 100 parts of an oxyalkylene polymer having at least one silicon-containing group containing a hydroxyl group and/or hydrolyzable group bound to a silicon atom and capable of crosslinking through the formation of a siloxane bond;(B) 1 to 150 parts of a high molecular weight and/or high viscosity plasticizer; and(c) 0.1 to 20 parts of a compound having one silanol group per molecular and/or a compound capable of reacting with moisture to thereby form one silanol group per molecule. When an alkyd paint is applied onto the surface of a cured material formed from this curable composition excellent coating properties can be obtained, the other physical characteristics of the cured material being maintained.
