Chromate Conversion Coatings

Chromate Conversion Coatings are chromate films. Chromate conversion leaves no measurable build-up on the part and provides excellent corrosion resistance. In many paint or adhesive applications, chromate is used as a base for superior bonding. Greater corrosion protection is provided with the formulations which give the golden coloring as these coatings tend to be thicker. The coating is conductive and offered in yellow iridescent to clear iridescent. Electrical resistance increases with the darkness of the yellow color. We use the Alodine brand.
