摘要: The present invention provides a method for forming a coating film, comprising the steps of:
(a) coating a metal panel with a cationic electrophoretic coating composition and heating the composition to form an electrophoretic coating,
(b) applying to the electrophoretic coating an aqueous primer containing a polyurethane emulsion prepared by subjecting a carboxyl-containing urethane prepolymer to chain extension by water,
(c) applying an intermediate coating composition to the primer surface,
(d) baking the aqueous primer and the intermediate coating composition at the same time, and
(e) applying a top coating composition to the cured coating and baking the composition.摘要翻译: 本发明提供一种形成涂膜的方法,包括以下步骤:(a)用阳离子电泳涂料组合物涂覆金属板,加热该组合物以形成电泳涂层,(b)向电泳涂层施加水溶液 底漆,其含有通过使含羧基的氨基甲酸酯预聚物通过水进行链延长而制备的聚氨酯乳液,(c)将中间涂料组合物施加到底漆表面,(d)同时烘烤水性底漆和中间涂料组合物, 和(e)将顶部涂料组合物施加到固化的涂层上并烘烤该组合物。 p
