The polyester is formed by a two-stage reaction of monomers consisting of carboxylic anhydrides having from 4 to 34 carbon atoms and polyols having from 2 to 20 carbon atoms. From about 10 to about 50% by weight of the monomers are anhydrides having the formula: ##STR1## where R.sup.1 is a non-aromatic hydrocarbon radical having from 6 to 30 carbon atoms, R.sup.2 is hydrogen or a non-aromatic hydrocarbon radical having from 1 to 8 carbon atoms. The total number of carbon atoms in R.sup.1 and R.sup.2 is from 8 to 30 carbon atoms. The polyester in conjunction with a hydroxyl-reactive curative provides a coating composition.

摘要： A thermosetting, organic solvent-based, primer coating composition for protecting metal surfaces which includes a solvent solution of: (a) a hydroxy-functional polyester resin; (b) a thermosetting acrylic resin; (c) a hydroxy-terminal polybutadiene resin, a hydroxy-terminal epoxidized polybutadiene resin, or mixtures thereof; (d) a blocked isocyanate crosslinker including at least one dimethyl pyrazole blocked isocyanate; (e) an aminoplast crosslinker including at least one melamine-formaldehyde condensate; (f) a catalyst; and, (g) a pigment. The primer exhibits excellent flexibility after curing to allow the primer to be coil coated onto metals as a thicker film and to have the metal subsequently formed without film fracture or loss of adhesion. The primer also has improved solvent release properties during curing to allow volatiles to readily escape therefrom, which facilitates coil coating of the primer onto metals as thicker films that, when cured into thick film hardened surface finishes, do not exhibit the typical blisters, craters, pops, voids and other surface defects. The primer can be cured as well at reduced temperatures which contributes to the reduction in surface defects. A fluorocarbon topcoat is usually coil coated and cured over the non-blistering primer coating, to yield a composite coated metal substrate having a surface finish that is free of blisters, craters, pops, and voids, and other surface defects.
摘要翻译：一种用于保护金属表面的热固性有机溶剂型底漆涂料组合物，其包括以下溶剂溶液：（a）羟基官能聚酯树脂; （b）热固性丙烯酸树脂; （c）羟基末端聚丁二烯树脂，羟基末端环氧化聚丁二烯树脂或其混合物; （d）包含至少一个二甲基吡唑封端异氰酸酯的封端异氰酸酯交联剂; （e）包含至少一种三聚氰胺 - 甲醛缩合物的氨基塑料交联剂; （f）催化剂; 和（g）颜料。该底漆在固化后显示出优异的柔韧性，以使底漆作为更厚的膜被卷绕在金属上，并且随后形成金属，而不会发生膜断裂或粘合丧失。该底漆还具有改善的固化过程中的溶剂释放性能，以使挥发物容易从其中逸出，这有利于底漆在金属上卷绕涂层，因为当固化成厚膜硬化表面处理时，较薄的膜不会出现典型的起泡，弹出，空隙等表面缺陷。底漆也可以在降低的温度下固化，这有助于减少表面缺陷。氟碳面漆通常在非起泡底漆涂层上卷曲涂覆并固化，得到具有表面光洁度的复合涂覆金属基材，其表面没有水泡，凹坑，气泡和空隙以及其它表面缺陷。

These polyurethanes are provided by the reaction of an organic diisocyanate with a stoichiometric excess of an essentially linear hydroxy-functional polyester which is the polyesterification reaction product of C.sub.4 -C.sub.10 aliphatic dicarboxylic acid or anhydride thereof with a stoichiometric excess of C.sub.3 -C.sub.8 aliphatic diol providing an alcohol/acid molar ratio of 3/2 to 6/5. The reaction is substantially complete as indicated by an acid number less than 10, and the diisocyanate is used in an amount providing an NCO/OH ratio of from 2/3 to 12/13. The thermosetting solution coating composition is provided by an organic solvent having dissolved therein from 5-50% of total resin solids of a curing agent reactive with hydroxy groups together with the polyurethane which has been described. The preferred curing agent is a partially methylolated melamine which contains from about 5 mol percent to about 40 mol percent of the methylol group.

摘要： A method of providing a stone chip-resistant finish to the undersurface of an automobile is disclosed in which the undersurface is coated with a cationically initiated liquid mixture of cationically curable polyepoxide, polyhydric alcohol, and a photoinitiator for an ultraviolet-activated cationic cure. The liquid mixture is applied at a resin solids content of at least about 50% and in a thickness to provide a cured coating of at least 2 mils thick, and the wet coating is cured by exposing it to ultraviolet light. The automobile undersurface is desirably primed with a cross-linked amine-functional polymer primer, and the coating includes from 1% to 8% of a finely divided silica which prevents running but does not interfere with the ultraviolet cure.
