Metalworking fluids is mainly used for metal processing and it mainly plays the role of lubrication and cooling, and has the functions of rust prevention and cleaning. it gernerally incudes cutting fluid, cutting oil, emulsion, stamping oil, quench agent, high temperature oil, extreme pressure cutting fluid, grinding fluid, rust proof oil, cleaning agent, blackening agent, deep drawing oil, thickener, etc. Dibasic acid mixtures like Novacid MA1 (same quality as Invista Corfree M1) ranging in length from DC10 to DC12 (Sebacic Acid, Dodecanedioic Acid (DDDA) and Undecanedioic Acid) can be formulated as an amine salt concentrate for a variety of corrosion inhibition applications.
