无铬达克罗比较资料

1、锌铝涂层（无铬达克罗）主要品牌产品性能比较研究 当前市场上已经获得大多数汽车和电器 OEM厂商认证的无铬达克罗技术主要有以 下四家：客观地讲，各家产品各有所长，共同的优点就是防锈性能好，均属于环保 和欧美市场准入产品。 但我们安美特的产品可以在涂层最薄的条件下防腐蚀性能 最佳，而且成本最低。实际上，很难公正地评价比较不同产品和技术的特点。经过 我们长时间的认真研究，对目前市场上可以获得的主流产品进行了比较研 究，研究结果见表 1 5。公主司主要产品底涂顶涂评论安美特Zin tek 200 / Zi ntek 2CTop|0- 230 °C80 - 200 ° C顶涂封闭所需
