Nacorr® 1351

Calcium salt of an aromatic sulfonic acid. Acts as a corrosion inhibitor. Exhibits good in-can viscosity stability and promotes pigment dispersion when a small amount is used in the grind. Reduces grind time, increases pigment loading, and improves color strength. Improves corrosion resistance by passivating the metal and improves water resistance by providing a barrier effect & reducing water permeation. Offers synergistic results when used in combination with anti-corrosive pigments such as strontium zinc phosphosilicate, zinc borate and barium metaborate. Applicable for aqueous air dry and thermoset coatings, waterborne primers, general industrial and maintenance coatings. Recommended usage levels include 1-3% based on the total weight of paint if used as the sole anti-corrosive agent, and 25-50% of the total anti-corrosive pigment loading when used in combination with other types of corrosion inhibiting pigments.
