Water Soluble Copper Rust Inhibitors T42

Water Soluble Copper Rust Inhibitor Lubricating Additives

Ultimate Copper Protection for Water-Based & Hybrid Fluid Systems

This premium rust inhibitor is soluble in water and ethylene glycol systems, used as a metal deactivated agent. It can replace solid Benzotriazole and solid methyl benzotriazole, effectively protect yellow metal and prevent cobalt spillover. This powerful rust inhibitor combines with conventional carboxylate rust inhibitors to provide comprehensive corrosion protection for a variety of metals. Ideal for all water based systems with pH >7 including antifreeze (engine coolant), high water based hydraulic fluid (HFC), water/glycol hydraulic fluid (HFC), metal working fluid (emulsion and synthetic fluid), and more.

Performance Features

Easy to operate, suitable substitutes for benzotriazole and methyl benzotriazole
Protect yellow metal and cobalt alloy from corrosion
Exceptional performance as a water-based rust inhibitor

Product Introduction

This Water-Soluble Copper Rust Inhibitor delivers atomic-scale protection through advanced azole chemistry. Engineered for aqueous environments, its pH-stable formulation forms self-assembled 0.7nm monolayers that prevent dezincification, pitting, and electrochemical corrosion in copper-rich systems, even with high chloride/sulfate contamination. This innovative rust inhibitor technology provides unmatched protection for critical water-based systems.

Forms defect-free monolayers within 30 seconds (AFM-validated 99.9% coverage).

Protects against 500 ppm chlorides + 300 ppm sulfates (ASTM D1384 modified).

Effective across pH 5–11 with <5% performance variance.

99% reduction in MIC (Microbially Induced Corrosion) (NACE TM0212)

<0.01 ppm heavy metals (21 CFR §178.3570).

Application
