Corrosion Test

AnCatt has conducted formal testing on our product. Our coated steel panels have successfully gone through 13,000 hours of Salt Fog Exposure (ASTM B 117) tests, and our coated aluminum panels have gone through over 10,000 hours. 5,000 hour is the maximum testing hours according to ASTM standards.

Tensile adhesion (pull-off strength) was measured in accordance with ASTM D 4541 following 1,100 Hours of cyclic weathering and 8,372 hours of salt fog exposure test. The adhesion by Tape test (ASTM D 3359) was performed after 8,372 hours of salt fog exposure. All our tests and result data used below are provided by KTA of Pittsburgh, PA — a well-known American Association for Laboratory Accreditation (A2LA) approved independent testing lab with over 60 years of experiences.

Results

Blistering and rusting are rated on a scale of 0 to 10. A “10” indicates no blistering or rusting or less than 0.01% of rust observed. After meticulously scratched off the black corrosion product, the undercutting appearing to be even narrower than the reported results displaying on this page.

Our Environment-Friendly Anti-Corrosion Coating Technology

Conducting polymer can be used as corrosion inhibitor was stated in 2000 Nobel Chemistry Award. In the past couple decades, many companies and organizations have tried to develop conductive polymer as a heavy-metal free and “smart” anti-corrosion pigments, and hundreds of patens have been filed on this topic. Recently, AnCatt Inc. utilized new concept combining with our unique conducting polymer (polyaniline) dispersion eventually brought this dream into reality.

Our anti-corrosion coating technology does not employ conventional toxic/carcinogenic heavy-metal anti-corrosion pigments such as chromates and lead compounds while providing heavy-duty corrosion protection to a wide range of metals including zinc and aluminum. This exciting anti-corrosion coating technology breakthrough provides an excellent solution to the urgent needs of Hexavalent Chromium-free anti-corrosion coatings for aluminum and its alloys. For steels, our technology provides a smarter solution with higher effectiveness, eco-friendly composition, scratch tolerant/self-healing, lower cost, and much longer performance life. We have frequently been told by the experts we have the strongest anti-corrosion coating they have ever seen.

Currently, we are seeking partners to licensing/commercialize this new technology. If you are interested in our anti-corrosion technologies or having questions/comments, please contact us.
