Product Description:
Ranbar Red P1250 is a translucent blue-light red monoazo pigment, Pigment Red 146, this product has bright color, high gloss, strong tinting strength, and good performance in water-based systems, its color is similar to Pigment Red 57 :1, slightly yellower than the hue, light resistance, heat resistance, solvent resistance, and sterilization resistance are slightly better than pigment red 57:1, because P1250 has poor heat resistance (190°C), so it is not For plastic applications requiring higher processing temperatures.

Applications:
Ranbar Red P1250 monoazo pigment is mainly used in the field of inks and coatings, recommended for water-based inks, gravure printing, and flexographic printing inks for packaging, offset printing inks, industrial finishes for interiors, latex paints, powder coatings, water-based architecture Decorative coatings, etc. Also used for textile printing, artist colors, and paper coloring, etc.
