RPKh-S synthetic coolant-cutting fluid (SOZh)
Area of application
RPKh-S SOZh is a component of 3-10% water solutions used as lubricant-anticorrosive agents in hydraulic presses, for piping compression test, as a coolant for welding mills and profiling machines.
- RPKh-S SOZh is a completely synthetic SOZh free of any oily or fatty substances. This makes it completely soluble in water, forming a clear solution, thus enabling easy metalwork operation.
- It contains no chlorine, sodium nitrite, phenols or other harmful components.
- The base material and additives used SOZh production provide reliable anticorrosion protection and improve tribological characteristics of the working surface, thus enhancing machinery durability and reliability.
- Biostatic, treatment solutions thereof have long-term bacteria- and fungi-resistance, which ensures long-life performance.
