Anwendungen

Methane sulfonic acid 70% solution is used virtually in all electronic applications involving tin or tin-alloy plating from non fluoborate systems. It replaces phosphoric acid in detergent formulations, thereby helping to avoid environmental phosphate pollution. It is used in the preparation of polyaniline/graphene nanocomposites, which enhances its thermal and electrical properties. It is utilized for electropolishing of aluminum as well as in electroplating of noble metals like gold, platinum, palladium and their alloys.

Bemerkungen

Light and heat sensitive. Keep the container tightly closed in a dry and well-ventilated place. Incompatible with amines, strong reducing agents, ethyl vinyl ether, hydrofluoric acid, strong oxidizing agents and bases.
