our pigments are highly-engineered ceramic colorants. they are impervious to sunlight, chemicals, and thermal attack. they are compatible with not only widely used polymers, but also the most exotic, difficult-to-formulate systems. their extreme inertness defends against migration from plastics or coatings, and helps to ensure environmentally sound, non-toxic recipes. vitreous enamel producers can count on shepherd pigments to withstand processing temperatures of more than 700 ° c. for more than three decades, shepherd color pigments have been the pigments of choice for premium coil coatings.
