It is an odorless chemical compound primarily used as an industrial paint coating. The compound is a beneficial coating because it is an anti-corrosive and an anti-rust primer. It is primarily used to coat aluminum and iron materials. Developed by the <a href=\"https:\/\/www.ford.com\/\">Ford Motor Company<\/a> during the 1920s, it was historically used on aircraft by the US military during the 1930s and 1940s. It is also widely used as a paint coating for the aerospace and automotive industries, as well as, a coating for boats, due to its ability to destroy organic growth on the surface and to protect aluminum from corrosion.<\/p>\r\n\r\n\r\n\r\n<p>Zinc chromate is on the hazardous substance list and regulated by OSHA because studies have shown that not only is zinc chromate highly toxic, but it is also a carcinogen. It has been cited by ACGIH, NIOSH, DEP, IARC, HHAG, and EPA.<\/p>\r\n\r\n\r\n\r\n<div class=\"wp-block-image\">\r\n<figure class=\"aligncenter size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-2318\" src=\"https:\/\/www.bottompaintstore.com\/blog\/wp-content\/uploads\/Duralux-Zinc-Kromate.gif\" alt=\"What is zinc chromate used for\" width=\"307\" height=\"331\" \/><\/figure>\r\n<\/div>\r\n\r\n\r\n\r\n<p><a href=\"https:\/\/www.bottompaintstore.com\/duralux-zinkromate-performance-primer-quart-p-10793.html?search=zinc%20chromate%20epoxy%20primer&amp;description=true&amp;sort=relevance&amp;order=DESC\">Duralux ZinKromate i<\/a>s a high-quality synthetic primer for use in light to moderate marine exposures.
