The US Navy seeks a partner to license and commercialize a suite of patented metal finishing conversion coating, etching, and primer technologies that do not use chromates
The Naval Undersea Warfare Center Division Newport has developed, tested, and patented Altite, a suite of technologies that use titanates in a drop-in process to replace hexavalent chromium commonly used to prevent corrosion on metals. The process also eliminates the need for ferro-cyanide in the bath, further reducing toxic elements and waste streams. Altite offers superior bonding performance compared to chromated products, especially in bonding titanium to carbon fiber composites.
Altite meets a variety of MIL-SPECS, including MIL-A-8625F for aluminum and aluminum alloys, and MIL-C-5541E for conversion coatings on aluminum. Product and application costs are competitive with existing processes. Personnel exposure concerns are vastly reduced compared to chromated products.
- No Chrome: Completely chrome-free technology utilizing titanate chemistries to impart corrosion resistance and establish superior bond strength
- Cost-Effective: Drop-in replacement with cost-competitive materials makes Altite an attractive alternative to current chromated processes and greatly reduces waste stream management costs
- No Cyanates: Altite does not not require the use of cyanates in the bath, further reducing costs, eliminating toxic materials, and lowering personnel exposure risks
- Broad Applications: NUWC has developed titanate-based no-chrome formulations for primers, etches, and conversion coatings for use on a variety of metal surface
