Polymer stability a problem? New Irganox® 1076 protects polymers against oxidation and thermal degradation under severe processing or service conditions. A nondiscoloring hindered phenol, Irganox 1076 improves retention of physical properties of polypropylene, polyethylene, rigid vinyls, polystyrene, acid-catalyzed UF-alkyd varnishes, hot-melt adhesives, etc. Photomicrographs: Surface crazing of polypropylene containing 0.25% Antioxidant A (left) and 0.25% Irganox 1076 (right) after 96 hours at 160° G.

Irgacet® solvent-soluble colors in transparent coatings offer brilliance with fastness to light, heat and chemicals. Use Irgacet colors in foil lacquers (nitrocellulose, vinyl, epoxy), fade-resistant NGR stains for quality furniture, flexographic and gravure inks, thermosetting epoxy and acrylic glass coatings, and clear plasticspolyesters, urethanes, polycarbonates, polystyrene, cellulose esters, acrylates and rigid vinyls, especially vinyl bottles.

Trace metals in food products often cause discoloration, oxidation, turbidity and corrosion, and impair taste, odor, texture and nutritional value. Food grade Sequestrene® EDTA chelating agents minimize trace-metal effects, are approved for use in more than twenty foods including salad dressings, oleomargarine, canned crabmeat, potato salad and frozen white potatoes, canned carbonated beverages, sandwich spreads, pecan pie filling, fermented malt beverages. Photographs: Canned kidney beans treated with 160 ppm Sequestrene NA2 (Na2 EDTA.2H20) retain fresher color and suffer less skin breakage than untreated beans at right.
