3Q-502 Metal Working Fluid Preservative

  • Product Overview

Our company's 3Q-502 metal working fluid preservative is a bactericide used directly in the working fluid during the metal processing. It sterilizes broad-spectrum, high-efficiency, and could kill varieties of bacteria, fungi and yeasts. The degradation of important components in the metalworking fluid due to microbial contamination in metalworking fluids results in a decrease in the viscosity of the fluid and a change in the pH value, which in turn causes corrosion and leakage of the machining system. The anaerobic bacteria in the processing liquid and the sulphate-reducing bacteria have a good effect of suppressing and killing.
