BECROSAN™ 2184 is an alkanolamine salt of a polycarboxylic acid which is a highly effective corrosion inhibitor for metalworking coolants and other waterbased products in contact with steel. When added to a metalworking fluid concentrate at a typical concentration of 2-10%, it will greatly reduce ferrous corrosion and improve results on the DIN 51 360 part 2, ASTM D4627, or IP 287 cast iron chip tests.
