Product Description
KHC3042 is a methyl benzotriazole derivative, soluble in water and ethylene glycol system, used as a metal deactivated agent. It can replace solid Benzotriazole and solid methyl benzotriazole, effectively protect yellow metal and prevent cobalt spillover. Its combination with the conventional carboxylate rust inhibitor can provide corrosion protection for a variety of metals.
Application & Recommended Dosage
All water based systems with PH>7: antifreeze (engine coolant), high water based hydraulic fluid (HFC), water/glycol hydraulic fluid (HFC), metal working fluid (emulsion and synthetic fluid), etc.
The recommended dosage is 0.1%-0.5%.
Performance Features
Easy to operate, suitable substitutes for benzotriazole and methyl benzotriazole.
Protect yellow metal and cobalt alloy from corrosion
Usage
Use with nitrite is not recommended because it may form nitrite amine.
It is recommended to use carboxylate rust inhibitors together, which can have a synergistic effect.
