阅读说明：本技术 低温固化1k底色漆及用1k底色漆涂覆基材的方法 (Low temperature curing 1K basecoat and method of coating a substrate with a 1K basecoat ) 是由 D·M·阿弗尔特 B·W·麦克德莫特 T·S·德桑布尔 D·H·坎贝尔 于 2018-07-03 设计创作，主要内容包括：本发明提供了一种储存稳定的单组分水性底色漆组合物,其包含三聚氰胺-甲醛交联剂和具有可在酸催化下与三聚氰胺-甲醛交联剂反应的基团的树脂。当与包含多异氰酸酯交联剂的溶剂型清漆组合物一起湿固化时,所述底色漆组合物可在110℃或更低的温度下固化。还提供了一种湿碰湿双涂层,其包含单组分水性底色漆和溶剂型清漆；一种湿碰湿三涂层,其包含水性底漆、单组分水性底色漆和溶剂型清漆层；和通过将湿碰湿双涂层固化而获得的固化面漆层。(The present invention provides a storage stable one-part waterborne basecoat composition comprising a melamine-formaldehyde crosslinker and a resin having groups reactive with the melamine-formaldehyde crosslinker under acid catalysis. The basecoat composition is curable at a temperature of 110 ℃ or less when moisture cured with a solvent borne clearcoat composition comprising a polyisocyanate crosslinker. Also provided is a wet-on-wet dual coating comprising a one-component waterborne basecoat and a solvent-borne clearcoat; a wet-on-wet tricoat comprising a water-borne base coat, a one-component water-borne base coat, and a solvent-borne clearcoat layer; and a cured topcoat layer obtained by curing the wet-on-wet double coating layer.)
