Metal deactivator BS42 is a water-soluble metal corrosion inhibitor additive. This product is a derivative of methylbenzotriazole. Its advantage is excellent metal corrosion inhibition performance in water-based environments. It can be applied to antifreeze systems, metal processing fluid systems, water ethylene glycol hydraulic oil systems, and other water-soluble products that require corrosion inhibition of metals.
CHARACTERISTICS
- Excellent metal corrosion inhibition.
- Good water solubility and compatibility in the formula.
- Used as a substitute for benzotriazole to prevent cobalt precipitation.
- Low odor and no irritating odor.
