Abstract
A room-temperature curable resin composition comprising (a) an acrylic polymer having a plurality of alicyclic epoxide functions, and (b) an amount effective to initiate the curing reaction at room-temperature of the acrylic polymer (a) of a proton-donating cation polymerization initiator. The composition finds its uses in coating compositions, sealants, potting and casting compositions.
Claims5
A curable resin composition comprising:
- (a) an acrylic polymer having a plurality of alicyclic epoxide functions and a number average molecular weight, of greater than 1,000, said acrylic polymer being a homopolymer of an acrylic monomer having at least one alicyclic epoxide function or a copolymer of said acrylic monomer with an ethylenically unsaturated monomer free from said alicyclic epoxide function and an alkoxysilane function;
- and
- (b) an amount effective to initiate the curing reaction of said acrylic polymer at room temperature of a cation polymerization initiator selected from the group consisting of a Bronsted acid, a Lewis acid, an amine trifluoromethane sulfonate, an amine tetrafluoroborate, an amine hexafluoroantimonate, an amine hexafluoroarsenate and an amine hexafluorophosphate.
