Acid etching eco friendly--The new version of an old technology proposed by Italtecno

摘要

Acid etching has been known and used since 1930. Recently the technology, abandoned for many decades, for many different technical reasons, has been recently brought on the market again with revised formulas mainly due to consideration of positive environmental impact compared to alkaline etching. This etching is specifically formulated in order to give a matt finish in short time with low consumption of caustic soda and low dissolution of aluminium.
