All the information on cadmium yellow

Cadmium yellow pigments are stable, inorganic colouring agents which are produced in a range of rich, vibrant shades of yellow, orange, red, and maroon. Modern day pigments are carefully engineered products manufactured in regulated chemical plants with full Health and Safety and Environmental permits under Responsible Care management and adherence. These cadmium yellow pigments have a carefully defined and engineered particle size, crystal structure, surface area and surface treatment to ensure they are not only correct for colour but also meet extremely low solubility and other key property limits.

The pigment chemistry is based on solid solutions of Cd,Zn, S, Se formed by calcining at high temperature to convert fully to a crystalline and stable hexagonal form, before undergoing a series of further treatments resulting in highly engineered pigment grade products.

These properties make cadmium yellow pigments unique. Being difficult to substitute, they are typically the materials of choice for ceramic, glass and metal decoration, plastic colouration and for the professional artist including restoration work.

Applications

Cadmium yellow pigments find niche applications in market segments where their unique blend of properties of clean colour shade, intensity, opacity, heat and light resistance and long-term stability are paramount.

Plastics

Cadmium yellow pigments have inherent high temperature resistance because of their method of manufacture and may therefore be used routinely in polymers which are processed at or above 300ÂșC e.g. polycarbonate, nylons and PTFE. Further, because of this high temperature resistance, all moulding sprues and off-cuts can be recycled whereas an organic may already be starting to undergo decomposition during moulding and be unable to withstand further heating.

Cadmium Yellow Medium

Cadmium Yellow Medium is a Series 4 opaque color. It has a
masstone of intense rich yellow, with a very similar undertone. It
has a strong Cadmium pigment which is sensitive to moisture and
should not be used outdoors.

Color Comparisons

Cadmium Yellow Light / Arylamide Yellow Light / Cadmium Yellow
Medium / Arylamide Yellow Deep / Cadmium Yellow Deep

In this sequence of bright yellows shown side by side it is
possible to compare the cadmium colours with similar arylamide
colours. Cadmium Yellow Light is distinctly greener that the other
colours shown here and should be compared to Transparent Yellow
which in masstone looks rather muddy but when White is added has
the same lemony yellow colour as Cadmium Yellow Light.

Arylamide Yellow Light sits between Cadmium Yellow Light and
Cadmium Yellow Medium and is a very bright and opaque colour.
Cadmium Yellow Medium is a mid point yellow colour and Arylamide
Yellow Deep always looks slightly muddy in masstone, but is bright
in tints, but not as bright as Cadmium Yellow Deep which is shown
next.

The long swatch at the bottom shows Arylamide Yellow Deep which is
transparent enough to be used as a glaze. The other yellows shown
here are rather too opaque to be used in glazing.
