Shepherd Color’s High-performance Pigments Meet EU Regulatory Requirements

Published on 2020-09-11. Author : SpecialChem

Green-pigmentThe Shepherd Color Company deployed their sizeable expertise in technical, analytical, and regulatory areas to find two high-performance pigment solutions. The pigments will overcome concerns raised about specific forms of nickel in standard Cobalt Titanate, CI Pigment 50 (PG50) in the European Union (EU).

Regulatory pressures dictate that old pigment chemistries meet new requirements or find their use curtailed or even eliminated. Very often, the new alternatives are of lower performance and higher cost, or both, but often with limited options. Shepherd Color addresses regulatory concerns and give their customers multiple options depending on what is most important to them and the environment.

First Route of Retaining Nickel in the Formula


The first route of retaining nickel in the formula, but ensuring that the nickel wasn’t present in the form of concern, yielded Green 10G655. This is a standard PG50 specially formulated and produced to meet EU labeling requirements, while maintaining a bright, chromatic green shade that PG50s are known for, and is more chromatic than other inorganic green pigments, such as chrome oxide (PG17).

Second Pathway - To Remove Nickel


A second pathway was to remove nickel from the pigment formulation altogether. Shepherd Color developed a bright chromatic green without nickel or chromium and launched it as Green 10G603. This product has a bright and chromatic masstone, excellent tint-strength and best of all, it is still classified as a PG50, so it has the same regulatory and chemical inventory approvals and listings.

Shepherd Color’s Green 10G603 and Green 10G655 represent the cutting edge in new pigment development.
