| abstract |
This invention relates to (meth)acrylate based polymerizable compositions and multipart adhesive systems prepared therefrom, which include an aziridine-containing compound in a carrier material with which the aziridine-containing compound is unreactive. The inventive composition demonstrates a flash point above 140° F., desirably above 200° F., for each of the parts of the adhesive system. To achieve the physical properties of the inventive compositions and adhesive systems, it is desirable for the carrier material to have such flash points; however, provided that in their entirety the inventive compositions and adhesive systems have such flash points, it is not necessary for the carrier material itself to have such flash points. The inventive compositions and adhesive systems also include a package for controlling the rate of cure and indicating the extent of cure. The inventive compositions and adhesive systems are particularly well suited to bonding applications which involve at least one low energy bonding surface, for example, polyolefin, polyethylene, and polypropylene surfaces. |
