Application of tall oil fatty acids: diesel anti-wear agent, alkyd resin, epoxy resin polyamide curing agent, synthetic lipid emulsifier, lubricating oil, metal working fluid, soap making, paint and coating, mineral processing flotation agent, etc.

In the application of cutting fluid, tall oil is mainly used to prepare emulsified cutting fluid and semi-synthetic cutting fluid. It has strong adaptability to hard water, and can also refine the emulsion particles, making the particle size smaller, making the solution more transparent and stable. In addition, tall oil, as an auxiliary emulsifier for cutting fluids, can reduce the usage amount of primary emulsifier. Compared with ordinary oleic acid, tall oil has faster emulsification speed, better lubricity, better cleaning performance, can play a certain anti-foaming effect and has good rancidity resistance performance.
