Tannin Stain Inhibiting Pigment
HALOX® BW-100 is a white, nonrefractive, tannin stain inhibiting pigment used in protective coating systems. It has been specifically designed as a tannin stain inhibitor providing performance and compatibility in a variety of resin systems such as acrylic latexes, vinyl acrylic latexes, styrenated acrylic latexes and solvent based alkyds.
HALOX® BW-100 blocks tannin stains in the primer layer of a two-coat system. It contains barium and calcium cations which chelate phenolic side groups found in tannic acid. It is low-cost and provides minimal hiding. Recommended loading levels range from 5-10% based on total formula weight.
