NACORR 1551
NACORR 1551 is a liquid corrosion inhibitor based on the zinc salt of an aromatic sulfonic acid.
ADVANTAGES:
Improves corrosion resistance as it passivates the metal
Synergistic results are obtained in combination with anti-corrosive pigments
Improves water resistance by providing a barrier effect and reducing water permeation of the coating
Enhances cure rate of amino crosslinked systems
Better stability, exhibiting good in-can viscosity stability
Promotes pigment dispersion when a small amount is used in the grind, thereby reducing grind time, increasing pigment loading, and improving color strength
Improves gloss properties when used as a dispersant in the grind
TYPICAL PROPERTIES:
Appearance: Clear, dark amber liquid
% Active: 50
Specific gravity, 25°C: 0.95
Volatile: Mineral Spirits
% Zinc: 3.5
APPLICATIONS:
NACORR 1551 can be used in most types of non-aqueous air dry and thermoset coatings. Recommended in primers, general industrial and maintenance type solvent-based coatings.
TYPICAL USAGE LEVELS:
1-3% based on the total weight of paint if used as the sole anti-corrosive agent. When used in combination with other types of corrosion inhibiting pigments, NACORR 1551 should be added at 25-50% of the total anti-corrosive pigment loading.
