Methanesulfonic Acid 70%

Methanesulfonic Acid 70% (MSA 70%) aqueous form facilitates handling, dosing and incorporation into liquid formulations. These properties make MSA 70% particularly suitable for industrial and professional cleaning, mineral-deposit removal, Clean-in-Place processes, surface treatment and selected metallurgical applications. MSA 70% may be evaluated as an alternative or complementary component in formulations based on traditional organic and mineral acids, particularly when low volatility, strong acidity, phosphorus-free formulation or effective mineral-deposit removal are required.
Application areas
Industrial Cleaning
MSA 70% can be used in formulations designed to remove mineral scale, inorganic deposits and metal oxides from industrial equipment. Its low volatility reduces the tendency to generate acid fumes compared with more volatile acids.
