Tego Coating and Ink Additives has introduced Tego LA-D 618, Tego LA-D 902 and Tego LA-D 903, additives that improve the compatibility of pigment concentrates in white bases for architectural coatings. These additives increase color strength, gloss and rub-out values in water-based and solvent-based formulations, according to the company. Tego LA-D 618 is 40% active in water, nonylphenolethoxylate-free and im-proves the compatibility of the pigment concentrates with the base in water-based systems. Tego LA-D 902, a 100% active, solvent-free compatibilizer, is suitable as a co-dispersing additive for the production of universal pigment concentrates for both water- and solvent-based systems. Tego LA-D 903 90% active compatibilizer is suitable as a co-dispersing additive for the production of universal pigment concentrates.
