Highly Effective Metal Protection

SHIELDEX® non-phosphate, chromium free anti-corrosive pigments protect metal when used in coil coating primers, general industrial primers, and primers for automotive and marine coatings. This highly effective, post-addable corrosion inhibitor provides a non-toxic alternative to chrome (VI) and zinc phosphate compounds to produce paints and radiation cured coatings. SHIELDEX® rust-inhibiting pigment performance has been extensively tested under a variety of conditions and has been proven by accelerated and innovative natural weathering technology.

Primer and direct-to-metal applications 

SHIELDEX® AC3 and AC5 silica: Ion-exchanged silica. Used for superior corrosion protection on exterior building panels. SHIELDEX® AC3 silica is for systems with DFT <20μ; SHIELDEX® AC5 silica is for systems with DFT >20μ.

Exterior and appliance applications 

SHIELDEX® C303 silica: Ion-exchanged silica. Used for superior corrosion protection in both exterior and interior applications.

Interior and exterior applications 

SHIELDEX® CS311 silica: Ion-exchanged silica. Used for superior corrosion protection in interior and exterior applications. Optimized curing stability, ideal for acid catalyzed systems.
