ADDITIN® RC 5800

Product Description

ADDITIN® RC 5800 is a highly effective liquid yellow metal deactivator designed to protect copper, cobalt, nickel and their alloys from corrosion in water-based fluid systems. Based on the sodium salt of tolyltriazole, it forms a thin, durable and virtually colorless protective film on metal surfaces, helping to maintain system performance and extend fluid service life.

By preventing the formation and accumulation of dissolved copper ions, ADDITIN® RC 5800 helps reduce metal-catalyzed oxidation and degradation processes. This not only protects yellow metals but can also help prevent corrosion issues on other metals within mixed-metal systems.

Key Benefits

• Effective corrosion protection for copper, cobalt, nickel and their alloys

• Prevents copper ion-related degradation processes

• Helps reduce corrosion risks in mixed-metal systems

• Forms a stable, virtually invisible protective film

• Effective at low treatment levels

• Easy handling and dosing due to liquid form

• Excellent solubility in water and glycols

• Compatible with a wide range of corrosion inhibitor technologies

Typical Applications

• Water-miscible metalworking fluids

• Metalworking emulsions and solutions

• HFC hydraulic fluids

• Water-based metal cleaners

• Antifreeze formulations

• Closed cooling and heating circuits

• Open cooling water systems

• Offset printing fountain solutions

• Disinfectant formulations

Formulation Advantages

ADDITIN® RC 5800 can be combined with commonly used corrosion inhibitors, including benzoates, silicates, nitrites, molybdates, phosphates and organic phosphorus compounds, to enhance overall corrosion protection performance. Its liquid form simplifies storage, handling and incorporation into formulations. In many applications, it can be used as an alternative to solid tolyltriazole products.
