Hostacor™ 3928 is a water-dispersible corrosion inhibitor with emulsifying properties used for metalworking fluids (emulsions, semi-synthetic, synthetic).
The product is clearly soluble in water, dispersible in mineral oils and compatible with non / anionic products. Mineral oil based formulations show no gelation tendency, form spontaneously emulsions and are stable in hard water.
