Production

Other Metalworking Fluids Additives

As one-stop solution of metalworking fluid, below products you can find from us easily to improve you overal properties of your products.

White Corrosion Inhibitor

When your products involve in the Aluminum, Zinc, Megnisium and other white metal, white corrosion inhibitor can help you to improve your products performance.

Anti rust agents/ additives

Corrosion inhibitors of ferrous metals are often called rust inhibitors or anti rust agent. In the process of processing different corrosion inhibitors need to be used different metal materials. We can customize corrosion inhibition products according to customer requirements.

Emulsifier

Different emulsifiers can be used in the metalworking fluid to enhance lubrication, and ensure that the water and oil components remain well-mixed, enabling efficient heat transfer

Lubricants for metalworking fluids reduce friction between the tool and workpiece, enhancing machining efficiency and tool life while improving surface finish.

Extrem Pressure agents

Extreme pressure agents (Anti-wear agent) for metalworking fluids form protective films on metal surfaces to withstand high pressures and temperatures during machining, reducing tool wear and improving process efficiency.

Specialty Amine

Specialty amines for metalworking fluids can act as corrosion inhibitors, pH buffers, or emulsifiers to enhance the performance and stability of the fluid.

Antioxidants

Antioxidants in metalworking fluids prevent oxidation and degradation of the fluid, ensuring its stability and longevity.

Lab Instruments

In order to meet customers’ requirements for formula stability and compatibility from our metalworking fluid, and to ensure the stability of our product quality, Syer Chem has increased investment in laboratory equipment.
