Advantages
HALOX® RC-980 does not contain tannic acid or phosphoric acid. It can be post-added to most vinylidene chloride binders used in rust conversion primers. It is less soluble and less acidic (pH 4-6) than tannic acid. HALOX® RC-980 provides better salt spray and cyclic corrosion performance and is non-flammable.
Features
HALOX® RC-980 is a low-odor, water miscible paint additive which converts red rust to black iron oxide.
Benefits
It is very cost-effective, and can be used in multiple binders (water-based and solvent-based).
Mechanism
Complexation with Fe3+.
Recommendations
Post-add to low pH water-based vinylidene chloride paints, suitable for low pH water-based coatings and some solvent-based coatings such as medium oil alkyds, cationic 1K epoxies, and cationic 1K acrylics.
