Hostacor 2732

Corrosion inhibitor for metal working fluids

Edition Date :
May 31, 2022
Hostacor 2732 is a liquified version of Hostacor IS and used as low foaming corrosion inhibitor in cutting & grinding fluids, in rolling emulsions and water-based hydraulic fluids (HFA-E, HFA-S).

Hostacor 2732 is insoluble in water. Water soluble salts of Hostacor 2732 are obtained by neutralization with alkanolamines and hydroxides. These are used alone or in combination with other water soluble corrosion inhibitors or lubricants.
 
Alkanolamines salts derived from Hostacor 2732 are excellent corrosion inhibitors for steel and show very good hard water stability.
