Abstract
This invention relates to cyanoacrylate-containing compositions that include, in addition to the cyanoacrylate component, the combination of two accelerators to improve fixture speeds on certain substrates.
Claims20
A cyanoacrylate adhesive composition comprising:
- (a) a cyanoacrylate component;
- and
- (b) an accelerator component consisting essentially of (i) calixarenes, oxacalixarenes, or a combination thereof, and (ii) at least one crown ether, wherein said composition exhibits a fixturing speed of less than 20 seconds for bonding two substrates, at least one of which is constructed of a material selected from the group consisting of steel, epoxy glass, and balsawood.
A cyanoacrylate adhesive composition comprising:
- (a) a cyanoacrylate component;
- (b) an accelerator component consisting essentially of (i) calixarenes, oxacalixarenes, or a combination thereof;
- and (ii) at least one crown ether;
- and
- (c) a thixotropic agent, therein said composition exhibits a fixturing speed of less than 20 seconds for bonding two substrates, at least one of which is constructed of a material selected from the group consisting of steel, epoxy glass, and balsawood.
