ABSTRACT:
A two-part composition curable by contact of respective parts with one another, comprising: a first part comprising a cationically polymerizable material and a first latent curing component; and a second part comprising a cationically polymerizable material and a second latent curing component which is reactive with the first component to form cations which are curingly effective for the resin. A preferred class of cation species comprises carbenium ions derived from reaction of organic halide compounds, as the first component, with silver salts of non-nucleophilic anions, e.g., 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.
