How Shepherd Color challenges the chemistry of pigments to address regulatory pressures

(Excerpt from Compounding World September 2019 Issue) Pigment chemistries continue to come under regulatory pressure, based on their chemical composition and physical forms as well as challenges from non-governmental organisations. “We continue to push the edge of currently used chemistry to find new pigments that address new regulatory pressures,” says Mark Ryan, Marketing Manager at Shepherd Color.

One example of this push is the company’s removal of nickel from the composition of its CI Pigment Green 50 (PG50), due in part at least to concerns in the EU. Pigment Green 50 is often used in place of green chromium oxide (PG17) because it is more chromatic and does not contain chromium. Shepherd Color’s Green 10G603 is free of both nickel and chromium and is literally “greener”. “It has an increased negative a* value that denotes how green in colour a pigment is,” explains Ryan.

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.
