Nickel - Free Green 50
Pigment Green 50 Pigments have traditionally
contained nickel as a color modifier. Due to health
concerns about nickel and especially nickel
titanium trioxide, Ferro has developed Pigment
Green 50 products which are free of nickel. These
products fall within the traditional description of
Pigment Green 50: Cobalt Titanate Green Spinel
(EC 269-047-4, CAS 68186-85-6, C.I. 77377). As
the constituent materials do not contain
intentionally added nickel compounds, these
products are not classified as hazardous under EU
REACH and CLP. The product codes for these new
nickel free greens are:
The new pigments have excellent chemical
resistance, outdoor durability, light fastness, heat
stability and are non-bleeding, non-migratory and
UV stable.
They are all-purpose pigments, suggested
applications include R-PVC, polyolefins and
engineering resins. These pigments cause no
warpage even in large injection-moulded or
extruded parts.
 PS 21-5801 Ni free Pigment green
 PS 21-5901 Ni free Pigment green
The new pigments also exhibit higher reflection at
wavelengths greater than 700 nm (IR region) than
nickel containing pigments and can therefore also
be recommended for heat management
applications.
We encourage our customers to test these
pigments in new or existing formulations. Our
technical laboratory team are available to help
facilitate the easy replacement of any nickelcontaining green pigment products with new nickel
free formulations.
Their outstanding fastness rating makes these
pigments ideally suited for plastics resistant to both
weathering and heat, notably for shading as well as
for mass tone. It makes it particularly suitable for
Paints and Coatings including General Industrial,
Coil and Extrusion coatings. Another suggested
field of application is for architectural finishes, both
water- and solvent-based.

Guide formulation to match nickel containing green
pigments
The following guide formulations show examples of the use of the new nickel free pigments in coating
applications to match the nickel containing pigments. Compounding ingredients, their concentrations and the
overall results have, however, not been optimized for production purposes. Different or additional raw
materials may be required for manufacturing suitable finished articles. The guide formulations are based on
European formulations with raw materials commonly used in Europe. For further information on these
products, the raw material supplier should be contacted directly.
