Abstract
Provided is a curable composition which contains: an organic peroxide encapsulated in microcapsules which further contains a plasticizer; an accelerator which reacts with the organic peroxide to accelerate polymerization; (meth)acrylate compounds which may contain a (meth)acrylate having a carboxylic group and a (meth)acrylate having an alicyclic hydrocarbon; and a multifunctional (meth)acrylate different from the (meth)acrylate having a carboxylic group. The curable composition exhibits a quick curing rate.
Claims9
A curable composition, comprising:
- (a) an organic peroxide encapsulated in a microcapsule;
- (b) an accelerator;
- (c) (meth)acrylate compounds, comprising (c-1) a (meth)acrylate having a carboxylic acid group, and (c-2) a (meth)acrylate having an alicyclic hydrocarbon;
- (d) a multifunctional (meth)acrylate different from the (c-1);
- (e) an elastomer;
- and
- (f) a core-shell graft copolymer;
- wherein
- the microcapsule further comprises a plasticizer,
- an average particle size of the microcapsule is from 180 to 300 μm,
- a content of the (c-1) (meth)acrylate having a carboxylic acid group is from 0.5 to 50 parts by mass per 100 parts by mass of a total amount of (a), (c), (d), (e) and (f), and
- a content of the (c-2) (meth)acrylate having an alicyclic hydrocarbon is from 5 to 80 parts by mass per 100 parts by mass of a total amount of (a), (c), (d), (e) and (f).
