Nacorr 6401 Zinc sulfonate King Industries Corrosion inhibitor Coatings >> Powder Coatings Coatings >> Solventborne Coatings >> Waterborne NACORR® RUST & CORROSION INHIBITORS Nacorr rust and corrosion inhibitors (Table 1) are metal or amine salts of modified sulfonic acids used to impart corrosion inhibition in aqueous and solvent-borne coatings. These products are liquid for ease of incorporation and, in addition to their primary function as an inhibitor, they can provide: Synergy with anti-corrosive pigments Improved pigment dispersion and gloss when incorporated in grinds (solvent-borne coatings) Reduction in cure temperature in amino crosslinked systems Protection in both clearcoats and pigmented systems An alternative for anti-corrosive pigments that are environmentally unacceptable Generally, additional levels of 1-3% on total weight of the paint are effective in enhancing corrosion protection. NACORR 6401 Zinc Free flowing powder for easy incorporation. Silica carrier. Free flowing powder of zinc sulfonate in a silica carrier. Used as a rust and corrosion inhibitor in powder, aqueous and solvent-borne coatings. Provides synergy with anti-corrosive pigments, improved pigment dispersion and gloss when incorporated in grinds (solvent-borne coatings), reduction in cure temperature in amino crosslinked systems and protection in clearcoats and pigmented systems. Offers easy incorporation. <br> Use level: 1-3% on total weight of the paint.
