摘要： The present invention relates to a weldable pre-primed coating composition, comprising binder resins, a crosslinker, an anti-corrosive pigment, conductive metal powder, carbon nanotubes, etc. The coating composition can be applied to a metal sheet before processing of the metal sheet to maximize the weldability, adhesion, corrosion resistance and processability of the metal sheet. Also, the coating composition can be applied to a metal sheet by a roll coating process to make it possible to eliminate not only an existing electrodeposition process which is carried out by a non-environmentally-friendly wet dipping process, but also an existing electrostatic spray primer coating process which is carried out by an electrostatic spray coating process in which a solvent is scattered, whereby the metal sheet coated with the coating composition has very excellent formability and weldability after its processing. Accordingly, the composition makes it possible to reduce the number of complex automotive coating processes, thereby greatly contributing an increase in productivity, a reduction in energy and an improvement in a work environment.
摘要翻译：本发明涉及一种可焊接预涂底漆涂料组合物，其中包括粘合剂树脂，交联剂，防腐颜料，导电金属粉末，碳纳米管等。涂料组合物可以在处理金属之前施加到金属片上以最大化金属板的可焊性，粘合性，耐腐蚀性和加工性。此外，通过辊涂法可以将涂料组合物施加到金属片上，以便不仅可以消除通过非环境友好的湿式浸渍方法进行的现有的电沉积工艺，而且可以消除现有的静电喷雾通过其中溶剂分散的静电喷涂方法进行的底漆涂布方法，由此涂覆有涂料组合物的金属板在其加工后具有非常优异的成形性和可焊性。因此，该组合物可以减少复杂的汽车涂覆工艺的数量，从而大大提高生产率，降低能量和改善工作环境。

摘要： The present invention relates to a highly scratch resistant one-part clear coating composition comprising a silane-modified blocked isocyanate for cars, in which a blocked isocyanate curing system comprising a silane functional group is applied besides an acrylic melamine-curing system used as a clear coat system for new cars unlike an acrylic-melamine curing clear coat used as a general clear coat for cars such that the formation of scratches on the surface of a car occurring during the automatic or manual car wash is minimized to maintain initial gloss for as long as possible, thereby maintaining the intrinsic color of the car as well as increasing a degree of consumer's satisfaction with the outer appearance of the car.
