Open the CIPO recordAbstract From the Canadian patent
Fast curing two part adhesives and articles bonded therewith are disclosed. The adhesives comprise a first part of free radical polymerizable acrylic monomers and a diazonium salt sufficient to initiate polymerization of said monomers. A second part comprises an activator to induce the free radical decomposition of the diazonium salt, said activator being an aldehyde-amine condensation product. The described curable adhesives are formed just prior to use where the second part containing the activator is placed in contact with the first part. Both the first part and second part component exhibit a high degree of stability when stored separately.
