Corrosion Inhibitors & Coatings for Construction

Technical Grade Sodium Nitrite Description: High-Purity Free Flowing Corrosion Inhibitor At Quimiconsult we offer BASF® technical grade Free Flowing Sodium Nitrite, a yellowish-white crystalline solid powder with a minimum purity of 99.0 g NaNO₂ per 100 g. It is a hygroscopic compound that is very soluble in water, used mainly as a corrosion inhibitor; it also shows antimicrobial properties and helps reduce odors in treatment systems and disinfection solutions. Its distinguishing feature is its Free Flowing condition: the powder does not cake or stick together, which makes it easier to handle, weigh, dose and dissolve in industrial processes. This is a real practical advantage in a hygroscopic product, whose conventional versions tend to cake in storage and must be broken up before use. As a corrosion inhibitor, sodium nitrite acts as an anodic passivator: in contact with steel and iron surfaces in aqueous media it promotes the formation of a stable, protective oxide film that slows c…
