    Abstract: Zinc or zinc alloy plated steel sheet ready for deep drawing coated with 1-5 gm/m.sup.2 of a dry, tack free continuous thermoplastic acrylic coating. The coating is formed by inductively heating the sheet to a temperature of about 149.degree.-246.degree. C. for no more than 10 seconds after being roll coated with a continuous liquid film of an aqueous solution including an acrylic polymer. The acrylic coating forms a protective film that is impervious to moisture, oil, and dirt, is able to be welded and adhesively bonded and possesses sufficient toughness and lubricity to allow deformation of the sheet without additional external lubricant. A deep drawn article formed from the sheet has enhanced painting characteristics after the acrylic coating is removed and the article is coated with a phosphate coating.

    Abstract translation: 锌或锌合金电镀钢板准备进行深冲涂,涂有1-5克/平方米的干燥,无粘性连续热塑性丙烯酸涂层。 在用包含丙烯酸类聚合物的水溶液的连续液膜进行辊涂之后,通过将片材感应加热至约149-246℃的温度不超过10秒形成涂层。 丙烯酸涂层形成不透水分,油污和污垢的保护膜,能够进行焊接和粘合,并具有足够的韧性和润滑性,从而允许片材变形而无需额外的外部润滑剂。 由片材形成的深拉制品在除去丙烯酸涂层并且制品涂覆有磷酸盐涂层之后具有增强的涂漆特性。
