Patent ID: 8304024

Claim:
A corrosion inhibiting curable composition for bonding galvanized surfaces comprising: (a) a first part comprising: (i) at least one curable (meth)acrylate component; (ii) a free-radical initiator component: (iii) a phosphate ester component; and (iv) an organic acid component; (b) a second part comprising one or more of an accelerator component, a carrier component, and a free radical initiator component, wherein at least one of the first part or the second part further comprises a corrosion inhibitor selected from metal phospho-silicates, alkali metal phospho-silicates, strontium zinc phosphosilicate, phosphate, phosphosilicate, calcium phosphosilicate, dialkylamino alkanoate metal salt, calcium ago phosphate, barium metaborate, ammonium benzoate, Vapor Phase Corrosion Inhibitor, benzothiazole succinate, 8-hydroxyquinoline, and combinations thereof, and wherein at least one of the phosphate ester component and the organic acid component are present in an amount sufficient to achieve a tensile strength on a galvanized surface of at least about 1000 psi when measured after humidity aging at 85% relative humidity and a temperature of 85° C. for a period of time of 250 hours or of at least about 2500 psi at room temperature.
