Novel Environment Friendly (Chromium-free) Primer Coating for Corrosion Protection
RFT-140
Since the early 1980’s, the use of chromates and other chromium-containing compounds have been subject to stringent regulations due to their recognized carcinogenic properties.
In an attempt to find a substitute for widely used chromium-based primer coating products, scientists at North Dakota State University have invented a novel, chrome–free primer coating with proven anti-corrosive properties on metal substrates The use of this primer eliminates risks associated with handling toxic and carcinogenic chromium metallic compounds, and alleviates waste disposal hazards.
This invention has been proven to be the only technology that protects high strength Aluminum alloys from corrosion, without the need of any chromate pretreatment or pigmentation.
