Ultramarine Violets are mostly used in Coatings to mask the yellowish tendency of some paints caused by the progressive degradation of the binder when exposed to UV light (solar or artificial).
However Ultramarine Violets are also highly appreciated for providing a very durable violet shade in “pastel” color façade paints. Unlike most of organic pigments, Ultramarine Violet is: Highly compatible with Titanium Dioxide when being formulated together; there is no chemical interaction between pigments that badly affects the outdoor durability of Ultramarine Violet Very easy-to-disperse.
Moreover, Ultramarine Violet is highly resistant to high ph media, therefore it is usable in Coatings made of highly alkaline binders (without the presence of high % of Calcium ions) e.g. silicate paints.
Other important characteristics of Ultramarine Violets when formulating Coatings are:
Ease to disperse and to wet
Excellent solvent fastness
Heat fastness (350ºC)
Excellent light fastness
High transparency, ideal situation when combining Ultramarine Violets with “Effect and Metallic pigments”
