Zinc chromate is used for a wide range of applications. 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 Ford Motor Company 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.

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.

Duralux ZinKromate is a high-quality synthetic primer for use in light to moderate marine exposures. It is lead and chromate free so it is safe to use; however, it offers all of the performance and quality characteristics of zinc chromate without the health and application hazards. It has good chemical and corrosion resistance, dries fast, and allows single finish coat coverage when using a like-colored topcoat. ZinKromate performance primer adheres very well to steel, iron, aluminum, or partially rusted galvanized surfaces.

S-76 Strontium Chromate Tack Coat Primer is for use on properly prepared steel, aluminum, or galvanized steel. S-76 is an anti-corrosive strontium chromate-based primer that is specifically designed for underwater metal surfaces including hulls, running gear, and the lower units of outboards and I/O’s. It provides an excellent barrier to reduce the pitting of the metal from galvanic corrosion.

Stromate Chromate tack coat primer may be used on bare aluminum in conjunction with Tuff Stuff High Build Epoxy to form a barrier for the application of copper-based antifoulants.
