About This Webinar
For decorative chrome plating there are various test methods used during production to measure corrosion behavior. For hexavalent chromium coatings specific tests were developed such as the copper sulfate test and checking active sites after CASS testing. However, these tests have occasionally been seen to show limited compatibility with trivalent chromium coatings.

As a pioneer in the field of trivalent chromium coatings with its renowned TriChrome® family, Atotech has developed a new test method specifically designed to provide reliable test results for trivalent chromium applications - the Fechner test. This test has been included in DIN 53100:2020.

In this webinar, the developer of the Fechner test, Dr. Mabya Fechner, will provide insights into corrosion protection provided by microporous systems for exterior automotive applications and will present the Fechner test and its application in detail, complemented by questions and answers on its use.
