ICL Phosphate Specialty - HALOX® Company Logo
HALOX® BW-191 is a white, non-refractive, corrosion-inhibiting pigment used in protective coating systems. It is recommended for use in most waterborne systems, such as latexes and water reducibles, and due to its lower oil absorption, it can also be effective in anticorrosive high-solids coatings. On the other hand, HALOX® BW-111 is recommended for use in solventborne epoxy systems, both conventional and high-solids.
