Coupling Agents

Coupling agents are used in a range of metalworking fluids where they optimise formulation homogeneity maximising the stability of both the concentrate and aqueous dilution. Metalworking applications include soluble oils, semi-synthetic and fully synthetic fluids.


Coupling agents provided by Lankem can be used to aid formulation metalworking fluid stability allowing optimum emulsifier and additive package selection. These products are based on fatty alcohol ethoxylates and fatty acid esters.

  • Lansurf SMO, Lansurf STO, Lansurf SMO81 and Lansurf STO85 are hydrophobic nonionic secondary emulsifiers using the formulation of soluble oils and semi-synthetic metalworking fluids. They can help balance the HLB of emulsification systems to give optimum emulsion stability.
