Ultramarines blues


Ultramarine Blues are the most widely used blue pigments in Plastics because of their unique coloristics and performance.

As regards color, Ultramarine Blues provide a unique reddish undertone blue color and are able to easily tint whites, greys and blacks with a bluish undertone that enhances the best of such colors. Moreover, Ultramarine Blues lack metamerism; therefore they do not change color in function of the iluminant.

As regards their performance in Plastics, Ultramarine Blues very well fit into such application because of their:
Compatibility with all kinds of polymers
Easy-dispersion
Maintenance of polymer’s dimensional stability
High heat fastness (350ºC, 5 min)
Excellent light fastness
Very good weather fastness, especially in the case of well-stabilized to UV light formulations
Good resistance to chemicals:
  To alkalis (without the presence of high % of Calcium ions), all grades
  To acids, only acid resistant grades
Insolubility, avoiding migration tendencies
High transparency, what make them very suitable to combine with “Effect and Metallic pigments” to reach unique color effects
Environmentally-friendly profile
Safe product in processing and final-use
