    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 about 0.25:1.0 to 2.0:1.0. In a second aspect, this invention is a primer comprising a solution of: (a) 5-50% of a polyester resin of a carboxylic acid and a glycol; (b) 5-50% of a polymethylene poly(phenyl isocyanate), diphenylmethane diisocyanate, or mixture thereof; (c) 0.1-50% of a silane-containing moiety; (d) 0.1-50% of a high boiling polar solvent; (e) 10-70% of an oxygenated solvent; and (f) 1-50% 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.
