众所周知,在当今的汽车生产中,底漆-面漆等涂装工艺可以大大提高汽车上金属体的外观质量。但是,油漆工艺最大的缺点是,漆中含有挥发性的、对人体有一定毒害作用的某些溶剂。为此,油漆厂家进行了大量的研究,以降低这些溶剂的含量。目前,美国和欧洲正在研究的水基底漆,可望取代现在使用的底漆。新型底漆成份的变化将导致油漆 As we all know, in today’s automobile production, primer - topcoat and other coating process can greatly improve the appearance of the car on the quality of metal body. However, one of the biggest drawbacks of the paint process is that the paint contains certain solvents that are volatile and have some toxic effects on the human body. To this end, paint manufacturers conducted a lot of research to reduce the content of these solvents. At present, water-based primers being studied in the United States and Europe are expected to replace the currently used primers. Changes in the composition of the new primer will lead to paint
