HALOX® SZP-391

1 of 36 products in this brand
HALOX® SZP-391 is a white, nonrefractive, corrosion-inhibiting pigment that is highly efficient and versatile. It is recommended for use in a wide variety of resin systems, such as alkyds (both traditional and high solids), epoxies, latexes, water-reducible alkyds, high acid value resins, catalyzed baking systems, and vinylidene chloride latexes. Its fine particle size and low oil absorption make HALOX® SZP-391 the preferred pigment for thin-film applications (<1 mil or 25 microns).

Chemical Family: Phosphosilicates, Strontium & Strontium Compounds, Zinc & Zinc Compounds

Functions: Corrosion Inhibitor, Pigment

Compatible Polymers & Resins: Alkyds, Epoxies (EP), Polyesters, Polyvinylidene Chloride (PVDC)
