Ultramarine Blue
Ultramarine Blue is an inorganic pigment whose colour has been classified as Pigment Blue 29, C.I. 77007 by the Colour Index System. Chemically it is a sodium alumino-sulphosilicate. This pigment is the synthetic form of Lazurite.
Ultramarine Bluehas got a clean and bright reddish blue shade. This makesUltramarine Bluedifferent than any other blue pigment of the market and due to this fact very attractive.
In addition to this very specific reddish blue shade, Ultramarine Blue is an excellent white corrector that neutralizes yellowish shades. Moreover, when usingUltramarine Bluefor this application, metamerism (= change of colour in function of the illuminant) does not occur. This whitening effect is widely appreciated in many fields of application e.g. detergency, plastics, paints.
| Plastics & Rubber |
|
Ultramarine Pigments maintain the dimensional stability of polyolefins and other polymers so that warping and shrinking do not take place
Compatible and suitable for all kind of polymers, from polyolefins to engineering polymers, including rubber as well
Ultramarine Blue is not only used to provide a reddish blue shade or to whiten polymers, but also to provide a blue undertone to grey and black plastic parts
Ultramarine Violet might be even more adequate than Ultramarine Blue to reduce the yellowish tendency of some resins and to provide a brightener white
