Coating agent for cured film

Abstract

Abstract PURPOSE:To provide the subject coating agent for a cured film, composed of a reactive monomer, a silicon-containing reactive polymer and a curing catalyst, excellent in weather resistance, adhesion, corrosion resistance and curability and useful, for formation of a coating film for protecting or decorating various kinds of materials. CONSTITUTION:This coating agent for a cured film contains (A) a reactive monomer (e.g. tetrahydrofurfurylacrylate) having a radically polymerizable double bond, (B) a silicon-containing reactive monomer soluble in (A), containing one or more reactive organic groups selected from formula I to formula VI (R<1> is H or methyl; R<2> is a 1 to 20C divalent organic group) and one or more Si which each form an SiOC bond through 0 together with the reactive organic group, having a structure where a part or all of Si are directly or indirectly bonded through an SiOC linkage to the main chain, exhibiting 1000 to 1000000 number-average molecular weight and preferably further containing R<3>O (R<3> is H a 1 to 20C alkyl, etc.) groups each bonded to Si and (C) a curing catalyst selected from a thermal polymerization initiator and a photopolymerization initiator.
