Lubricant additive Ricinoleic acid polyester for metalworking fluids

Lubricant additive Ricinoleic acid polyester for metalworking fluids

Item No.: ML-4

Poly ricinoleic acid ML-4 is a ricinoleic acid polyester compound that can be used as a lubricity additive for water-based metalworking fluids. ML-4 has a certain degree of self-emulsification, it is very easy to emulsify in the presence of a small amount of alkali, it is easy to add to the aqueous formulation system, and has good hydrolytic stability. The strong polarity of the structure makes it have good lubricating performance, and it is recommended for cutting and rolling of aluminum.
