Product description
STD 22-5070 is a blue Cobalt Chromite spinel.
It has excellent chemical resistance, outdoor durability, lightfastness, thermal stability and does not bleed or migrate. It is a general purpose pigment and suggested applications include RPVC, polyolefins, engineering resins. This pigment does not cause warping of injection molded or extruded parts, even large parts. Its outstanding fastness ratings make this pigment ideal for weather and heat resistant plastics, especially for light blocking and primary colors. This makes it particularly suitable for paints and coatings, including general industrial, coil and extrusion coatings. Another application area is textiles, architectural finishes (waterborne and solventborne).
