PRESS RELEASE: The Shepherd Color Company Announces Their Newest Addition to the NTP Yellow Product Portfolio


(CINCINNATI, OH, April 18, 2019) Shepherd Color is excited to announce the newest addition to their NTP Yellow product portfolio, NTP Yellow 10G155. This new product brings the outstanding color, opacity, and durability that people have seen in NTP Yellow, but further expands the durable color envelope to new applications.

Paint and coatings chemists, formulators, and color matchers face many challenges and options for coloring in the yellow color space. A wide range of pigment chemistries are available with different levels of opacity, durability, chromaticity, and economics. These four properties are often antagonistic to each other, forcing a compromise on two or more of these key properties. At the same time, historical pigments like lead chromate are facing increasing regulatory pressure and are being formulated out of products.

The yellow color space has a wide range of pigment options that have a balance of chromaticity, opacity and durability. The new NTP Yellow (PY227) brings bright chromatic color, high opacity, and excellent durability all at the same time. This has lead a plastics engineer to call it ‘bullet-proof” colorant. To complement the NTP Yellow, improvements of the RTZ Orange (PY216) yield a true orange color unto itself, but also allows the addition of “a* value” or redness to color matches without compromising weathering or heat stability.

Color matches that used to depend on blends of organic and inorganic pigments can now be matched with all inorganic pigments for the ultimate in durability and a true expansion of the durable color envelope.

The NTP Yellow and RTZ Orange are compatible with a wide range of polymers in coatings and plastics for use in a wide range of applications, such as:

  • Pre-painted coil and extrusion
  • Engineering polymers
  • Laminates and co-extrusions
  • Powder coatings
  • Architectural and façade coatings

Shepherd Color’s newest addition to their NTP Yellow product portfolio, NTP Yellow 10G155, brings the outstanding color, opacity, and durability that people have seen in NTP Yellow, but in a color shade closer to red-shade bismuth vanadate (PY184) pigments. It has higher heat stability and excellent weathering properties. Other key features of Yellow 10G155 include: inertness to acids, bases, solvent and UV, no chromium or lead in the formulation, halogen-free, and non-warping in polyolefins.

The Shepherd Color Company Attending the 2019 European Coatings Show

Highlighting Two Unique and Ground-breaking Technologies

The Shepherd Color Company will be attending the European Coatings Show (ECS) in Nuremberg, Germany March 18-21, 2019.

144 presentations in 24 sessions, 10 short courses and countless networking possibilities. Over the course of just two-and-a-half days, the European Coatings Show Conference offers everything you need to thrive in the fiercely contested coatings market: current developments in raw materials, the latest results from scientific institutes and universities, and contact with leading international experts in person.

At the ECS, Shepherd Color will be supporting their high-durability and specialized pigments that have made them the standard for highly demanding applications like Coil and Extrusion coatings, high-heat coatings and other specialty coatings. Shepherd Color pigments also have functional properties such as the Arctic IR Reflective pigments that keep materials cooler and the Dynamix easily-dispersed technology that takes production steps and costs out of making color dispersions. At the ECS, Shepherd Color will be highlighting two key technologies: the unique and ground-breaking NTP Yellow and the new and improved RTZ Orange. These two pigments give formulators and chemists key tools to address chromaticity, opacity, and durability in the color space formerly held by lead chromates.

“Together these pigments provide high chroma, opacity, and durability solutions to coloring in the yellow-orange color space. These highly engineered pigments are excellent colorants for demanding thin film applications and are compatible with a wide range of resins,” said Mark Ryan, Marketing Manager for Shepherd Color.
