AnCatt has conducted certified third-party corrosion testing on our anti-corrosion coating product by accredited independent corrosion test labs. Our coated steel panels have successfully gone through 13,740 hours of Salt Fog Exposure (ASTM B 117) tests and still not rusting, blistering or creeping at the scribe line, and our coated aluminum panels have gone through over 10,000 hours and remained intact. We only stopped because the result is impressive enough, and we still don’t know when the rust will come out yet, and we cannot wait any longer.  5,000 hour is the maximum testing hours according to ASTM standards.  ASTM B 117 salt fog corrosion test share same testing parameter with ISO 9227 salt spray test, therefore, the test result hours is inter-changeable, 13,740 hours of ASTM B 117 is equivalent to 13,740 hours of ISO 9227 test.

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.  The new SAE J2334 – Chassis, test report was performed and certified by Element Independent Corrosion Test lab. 


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.
