Abstract

The effectiveness of the protection of the base metal by the popular corrosion inhibitor BTA (1,2,3-benzotriazole) depending on the method of application of the inhibitor was verified on lead coupons in an environment contaminated with acetic acid. The BTA inhibitor was applied alone or in combination with a protective wax and/or varnish coating: a multi-layer system (BTA-single-layer wax/varnish, BTA-double-layer wax+varnish) or a BTA additive to the wax/varnish coating. As part of a long-term experiment (almost 2 years), the effect of the length of immersion of the metal in the BTA solution and the effect of aging of the protective coating on its anti-corrosion effectiveness and visual changes of the base metal were monitored.

Keywords: BTA, protective coatings, lead corrosion, corrosion inhibitors
