Abstract
An instant-setting adhesive composition comprising a 2-cyanoacrylate and at least one 1,1-disubstituted diene, the amount of said 1,1-disubstituted diene exceeding 50% by weight based on the total weight of both components. This composition is useful in the same fields as those where conventional 2-cyanoacrylate adhesives have been used, and is excellent in impact resistance, peel resistance, heat resistance and water resistance.
Claims19
An instant-setting adhesive composition comprising a 2-cyanoacrylate and at least one 1,1-disubstituted diene represented by the following general formula (A), the amount of said 1,1-disubstituted diene being more than 50% by weight but not more than 90% by weight based on the total amount of both components:
- ##STR3## wherein R.sub.1 is a hydrogen atom, an alkyl group having 1 to 5 carbon atoms, an aryl group, an aralkyl group or a halogen atom, R.sub.2 is a hydrogen atom or an alkyl group having 1 to 5 carbon atoms, and X and Y, which may be the same or different, are selected from the group consisting of cyano group, carboxylate group, ethylsulfone group, phenylsulfone group, formyl group, acetyl group, benzoyl group, diethylphosphonyl group, amido group and phenyl group.
