有机缓蚀剂？

tank

看到资料上说一些有机缓蚀剂如2-巯基苯并咪唑、噻唑等有较好的使用效果，有用过的朋友能否介绍一下优点、缺点？

苯并咪唑和苯并三氮唑之类还是主要用于助焊剂居多吧，特别是在水下作业的时候。试过在五金金属烤漆里还是有一些帮助的。

Why go organic?
The coatings industry is being challenged by an ever-increasing number of regulatory initiatives designed to protect the environment and workers. Most obvious among these are VOC limitations, HAP  restrictions, and increasing pressure on heavy metals. The net effect is a shift toward water-borne, powder, or high solids systems, and replacement of questionable heavy metals wherever possible.

Traditionally, heavy-metal based anti-corrosive pigments have been used but these are either being phased out, such as hexavalent chromate, or might not be well suited, for
example, in water-borne coatings. *****® offers a range of organic corrosion inhibitors that are specifically designed to address future environmental and worker safety needs for
coatings over various metal substrates.
If you are looking for an alternative to heavy metal containing corrosion inhibitors, *****® Organic Corrosion Inhibitors could be exactly what you are looking for. These heavy metal free inhibitors are used at additive levels and can replace traditional heavy metal-based anti-corrosive pigments, along with their environmental and worker safety concerns. In addition to their excellent performance, *****® Organic corrosion inhibitors can improve wetting and adhesion over traditional corrosion inhibitors. They can also be formulated to provide coatings with high gloss, and can even be used for corrosion-resistant clear coats.

还是有些途径可以搞到，不过以前试过两只粉体好像也没有多么突出加上价格又离谱。。。
