IRGAMET 42 Water soluble metal deactivator
Typical chemical and IRGAMET 42 is a liquid, water / glycol soluble, tolutriazole derivative which acts as a
physical properties metal deactivator
Applications and typical treat levels recommended
All types of water based fluids,when used at 0.1 - 0.3% with pH > 7, such as :
Antifreeze (engine coolants)
High water based hydraulic fluids (HFA)
Water glycol hydraulic fluids (HFC)
Metal working fluids (emulsions and synthetics)
Benefits
Easy to handle liquid
Suitable replacement for benzotriazole and tolutriazole
Protects yellow metals and cobalt alloys from corrosion
Restrictions
Not recommended for use in combination with nitrites due to the possible formation of nitrosamines
May begin to crystallise if stored at temperatures below 5 °C in water and in glycols there is a solubility gap.
