摘要： The invention provides thermosetting coating compositions in which acrylic copolymers are used as carriers for fluorocarbon resins. The compositions have a combination of high fluorocarbon content, high solids content, and a low viscosity suitable for coil coating. Thus, the solids are borne in organic solvent systems which permit minimization of the viscosity and a moderate evaporation rate. The solvent system has a &dgr;H of from 1.7 to 2.6 (calories/cubic centimeter)½ and a &dgr;V of from 8 to 9.5 (calories/cubic centimeter)½ and is exemplified by a mixture of 4 or more of the following solvents: aliphatic ketones having from 4 to 10 carbon atoms, alkyl esters having a total of from 5 to 7 carbon atoms, aromatic acid esters having from 8 to 12 carbon atoms, lactones, and aromatic solvents. The acrylic polymer is comprised of (a) acrylic esters having no additional functionality, (b) acrylic esters having additional functionality by which the acrylic polymer may be cross-linked, and (c) an acryloxyalkyl oxazolidine.

摘要： This invention relates to a method for embedding a multiplicity of discrete masses of material in a resinous coating on a sheet of metal in a coil coating system. The sheet is coated, the masses are embedded in the wet resinous coating, and the coating is dried in a one-pass system. The resinous coating and the embedded masses are preferably resistant to ultra-violet radiation. The wet resinous coating, therefore, is preferably a liquid fluorocarbon resin. The discrete masses comprise pigmented particulate minerals and resins in the form of granules, beads, vesiculated beads, pellets, flakes, platelets, cylinders, coating powders, and coating powder precursor chips. The minerals include glass, quartz, mica, pebbles, and ceramics. The particulate resins include polyesters, acrylics, nylons, polyurethanes, polycarbonates, solid fluorocarbon resins, and solid mixtures of a fluorocarbon resin and an acrylate or methacrylate polymer or copolymer. Sheet metal decorated in such a manner is useful as stock in the manufacture of metal roofing shingles simulating the appearance of traditional asphalt shingles.

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。
