Iron phosphating with subsequent passivation has been the standard process for the treatment of metal surfaces prior to painting. Now, Henkel has introduced a 'nanoceramic' coating process that is claimed to be far superior to this traditional method. Bonderite NT coatings can be applied at room temperature and are suitable as a surface pre-treatment for all conventional powder and wet paint applications. No subsequent passivation is required, thereby eliminating a complete process step. It is particularly fast, with most parts being treated in only 20 seconds.
