Product Description

Ultramarine Blue (Green Shade) is an intense deep greenish-shade blue color from inorganic pigment of sodium aluminum silicate composition. It is a transparent, fine grained color with high tinting strength. This ultramarine blue is ground in linseed oil without additives to change the effect of the pigment and oil mixture. As a result, the paint is long producing slightly stringy brushmarks due to the hydrophilic nature of ultramarine. Although ultramarine oil paint is not unique, this is a novel variation of this popular color.
Ultramarine pigments are sodium aluminum silicates with small sulfur containing anions (e.g., S3 and/or S2) bound as chromospheres in the interstices of the crystal lattice to equalize the charge. Depending on composition, blue, red, green or violet pigments can be obtained, the hue being altered by varying the amount of silica. Ultramarine pigments have a high heat resistance but their universal use in paint is limited on account of their poor hiding power and limited weather resistance. Special types of ultramarine pigments are coated with silica to reduce ultramarine's susceptibility to acid and improve its weather resistance.
