Shepherd Color Company Announced The Development of a New Pigment Chemistry

The Shepherd Color Company announced the development of a new pigment chemistry offers excellent durability, high opacity and a bright clean yellow color. Niobium Tin Pyrochlore (NTP) Yellow is an innovative inorganic pigment that expands the envelope of durable color, according to the company.  It is a bridge between the high-chromaticity of organic pigments with the durability and opacity of inorganic pigments. The NTP Yellow is a new class of Complex Inorganic Colored Pigment (CICP) under the designation Pigment Yellow 227 and is covered by a number of patents around the world. The NTP Yellow 10P150 is specifically engineered for plastics applications while the NTP Yellow 10C151 is tailored for coatings and paints. The new pigment is gaining new regulatory approvals and chemical inventory listings almost daily. Please contact your local Shepherd Color representative for local market availability.

To compliment the NTP Yellow, Shepherd Color is also introducing an improvement of a current product line with a brand new offerings in our Rutile Tin Zinc (RTZ) Orange pigments. RTZ Orange 10P340 for plastics and RTZ Orange 10C341 for coatings offer increased redness, higher heat stability and excellent weathering when compared to current market offerings.

The NTP Yellow and RTZ Orange expand the durable color envelope that is available to color stylists, architects and designers for high-value systems where the highest performance is required. They also make excellent replacements for colors based on lead chromate pigments color space and provide paint chemists and formulators with high-performance environmentally friendly alternative colorants. For plastics, the pigments provide high-temperature stable bright colors for engineering polymers. The inherent stability makes them capable of standing up to the high pH of inorganic binder systems. Both RTZ and NTP are compatible with a wide range of binder systems and processing parameters.
