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.
