| titleOfInvention | Primer composition for improving the bonding of urethane adhesives to acid resistant paints |
| abstract | In one aspect, this invention is a primer comprising a solution of: (a) a polyester resin of a carboxylic acid and a glycol; (b) a polymethylene poly(phenyl isocyanate), diphenylmethane diisocyanate, or mixture thereof; and (c) a silane-containing moiety; in a solvent mixture comprising: (i) a high boiling polar solvent; (ii) an oxygenated solvent; and (iii) an aromatic solvent; wherein the weight ratio of (a):(b) is in the range of from 0.25:1.0 to 2.0:1Ø In a second aspect, this invention is a primer comprising a solution of: (a) 5 to 50 percent of a polyester resin of a carboxylic acid and a glycol; (b) 5 to 50 percent of a polymethylene poly(phenyl isocyanate), diphenylmethane diisocyanate, or mixture thereof; (c) 0.1 to 50 percent of a silane-containing moiety; (d) 0.1 to 50 percent of a high boiling polar solvent; (e) 10 to 70 percent of an oxygenated solvent; and (f) 1 to 50 percent of an aromatic solvent. It has been discovered that the primer of the invention advantageously provides improved adhesion characteristics of metal-to-glass bonding when used to prime acid resistant paint-coated metal substrates before applying a urethane adhesive, particularly when used with a "fast cure" adhesive comprising an isocyanate-functional prepolymer and dimorpholinediethyl ether. |
