BASF这个不用说吧,德国企业,全球最大化工企业.杜邦刚把汽车涂料业务卖给了凯雷,49亿美元.PPG是美国最大涂料企业,KANSAI这是日本关西企业,日本最大汽车涂料企业,在长沙有合资厂湘江关西,还有中远关西,NIPPON,立邦漆,立邦就是日本的音译,反而是中国家装漆的最大市场占有者,说中国反日,先停用立邦漆,KCC是韩国企业.
汽车涂料要经过大约5道工序,第一道是预处理Pretreatment,Conversion coating thatimproves corrosion resistance and paintAdhesion,主要是提高涂料与车体的黏合强度,其次是提高防腐蚀能力。第二道是电泳Electrocoat, Electricallydeposited coating that protects metal fromcorrosion,电泳的好处是覆盖面广,电泳漆在非常隐蔽的部位,如翻边以及箱式结构,仍能形成完整的保护膜,从而得到较高的防腐蚀性。(Formationof protective films in highly recessed areas such as flanges andbox sections provides critical corrosion protection)
Transfer efficiencies of better than 95% result in reduced paintwaste, especially when compared with spray-applied coatings.
第三道是中涂 Primer Surfacer,Spray applied coating that improvessurface smoothness, durability and protects againstchip。可以提高汽车表面光洁度。第四道是底漆Basecoat,也是最重要的一道工序, Color coat that addsthe decorative chroma and aestheticeffects,色彩和装饰效果都取决于Basecoat。最后是清漆Clearcoat,Final coating layer thatprovides protection and shine to the vehicle to maintain it’sshowroom like finish |
