    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.

    Abstract translation: 一方面，本发明是一种底漆，其包含以下溶液：（a）羧酸和二醇的聚酯树脂; （b）聚亚甲基聚（苯基异氰酸酯），二苯基甲烷二异氰酸酯或其混合物; 和（c）含硅烷的部分; 在溶剂混合物中，包括：（i）高沸点极性溶剂; （ii）氧化溶剂; 和（iii）芳族溶剂; 其中（a）：（b）的重量比在约0.25:1.0-2.0:1.0的范围内。 在第二方面，本发明是一种底漆，其包含以下溶液：（a）5-50％的羧酸和二醇的聚酯树脂; （b）5-50％的聚亚甲基聚（苯基异氰酸酯），二苯基甲烷二异氰酸酯或其混合物; （c）0.1-50％的含硅烷部分; （d）0.1-50％的高沸点极性溶剂; （e）10-70％的氧化溶剂; 和（f）1-50％的芳族溶剂。 已经发现，本发明的底漆在施加氨基甲酸乙酯粘合剂之前，特别是当与“快速固化”粘合剂一起使用时，有利地提供金属对玻璃粘合剂的改善的粘合特性，所述粘合特性用于在耐酸漆涂覆的金属基材上浇注， 异氰酸酯官能预聚物和二吗啉二乙醚。

    Abstract: In a curable composition that contains at least one polymer having at least one terminal group of the general formula (I) -An-R—SiXYZ  (I), at least one cyclic compound that contains at least one structural motif of formula (II) as a constituent of the ring structure; and at least one cyclohexanedicarboxylic acid dialkyl ester in which the alkyl residues of the ester groups each, mutually independently, contain 1 to 20 carbon atoms. The curable composition can be used as an adhesive, sealant, and/or coating material. A combination of a cyclohexanedicarboxylic acid dialkyl ester, in which the alkyl residues of the ester groups each, mutually independently, contain 1 to 20 carbon atoms and a cyclic compound that contains at least one structural motif of the general formula (II) as a constituent of the ring structure, as a plasticizer/curing catalyst system in curable compositions.
