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.
Grace’s new SHIELDEX® C 500 anti-corrosive pigment combines effective anti-corrosive properties in an economical and environmentally safe product. With improved corrosion resistance, the latest generation of our SHIELDEX® silica product is ideal for any coil or metal coating application.
