ABSTRACT:
A co-curable composition, having utility as a first part of a two-part cationically curable composition and containing a latent curing component which is reactive with a latent curing component in a second part of the two-part composition to form curingly effective cations for the two-part composition, such co-curable composition comprising: (i) a cationically polymerizable material, and (ii) a dioxane-complexed metal salt of a non-nucleophilic anion. Also disclosed is a two-part composition curable by contact of respective parts with one another, comprising first and second parts of the aforementioned types. A preferred class of cation species comprises carbenium ions derived from reaction of an organic halide compound, as the first component, with a metal salt of a non-nucleophilic anion such as SbCl.sub.6.sup.-, SbCl.sub.3.sup.-, SbF.sub.6.sup.-, AsF.sub.6.sup.-, SnCl.sub.5.sup.-, PF.sub.6.sup.-, BF.sub.4.sup.-, CF.sub.3 SO.sub.3.sup.-, and ClO.sub.4.sup.-, as the second component. The respective parts of the two-part composition may be applied to matable surfaces which then are contacted to effect rapid bonding cure of the composition.
