HAVE YOU TRIED THIS THICKER THICKENER? New...Nonionic...High Efficiency...Water Soluble NATROSOL® 250—Hercules hydroxyethyl cellulose—has wide utility as a thickener and stabilizer in a variety of water-based systems—from emulsion paints and latex coatings to vinyl polymerization reactions and burn out binder compositions. It may be useful to you. It is available in an extra-high viscosity grade (20,000 cps. at 2% in water), as well as in the regular lower-viscosity types. And, it is granular in form, dissolving readily in water of any temperature to give clear, haze-free solutions. Since it is nonionic, NATROSOL 250 has wide
tolerance for salts, acids, alkalies, and alcohols as well. It imparts good brushing and leveling characteristics, and thus contributes positively to the performance of the finished paint formulation. The high-viscosity types of NATROSOL 250 are used for thickening and pigment suspension; the lower-viscosity types as protective colloids, and as stabilizers in emulsion polymerization. If you have not already tried this easy-to-use, stable, high-efficiency colloid, may we send you a one-pound trial sample of the viscosity grade of NATROSOL 250 you need?
