Abstract
The present invention provides two part, room-temperature curable epoxy resin/(meth)acrylate compositions. The compositions provide among other advantageous properties high flash point and low odor, and reaction products thereof demonstrate at least comparable and often improved fixture time, improved adhesion strength, and improved adhesion strength over time, to substrates which are ordinarily difficult to bond (such as plastics) with epoxy-based compositions, as contrasted to commercially available comparable products that are of low flash point and higher odor.
Claims25
A two-part, room-temperature curable composition having high flash point and low odor, comprising:
- (a) a first component, comprising:
- (i) an epoxy resin, and
- (ii) (meth)acrylate component;
- and
- (b) a second component, comprising:
- (i) an epoxy resin hardener, and
- (ii) a catalyst comprising a transition metal complex,
- wherein at least one of the first component or the second component, wherein cured reaction products of the composition demonstrate at least substantial maintenance of at least one physical property selected from the group consisting of fixture time, adhesion strength, and adhesion strength over time, after exposure to at least one condition selected from the group consisting of elevated temperatures, moisture and a chemical environment.
