Document Type and Number:
WIPO Patent Application WO/2020/170908
Kind Code:
A1
Abstract:
A multiple package-type curable composition which comprises: an agent A that contains (A) a polyoxyalkylene polymer having a reactive silicon group, (B) a (meth)acrylic acid ester polymer having a reactive silicon group, and (D) an epoxy resin curing agent; and an agent B that contains (C) an epoxy resin and (E) a silanol condensation catalyst. The (meth)acrylic acid ester polymer (B) comprises, as constituent monomers, from 40% by weight to 70% by weight (inclusive) of (b1) a (meth)acrylic acid alkyl ester wherein an alkyl group has 1-3 carbon atoms, (b2) a monomer having a reactive silicon group and a polymerizable unsaturated group, and (b3) a macromonomer that is a (meth)acrylic acid ester polymer having a polymerizable unsaturated group.
