Pigment Red 21 for Coatings and Textile Printing

Pigment Red 21 is a monoazo pigment with a yellowish-red shade (often called "Scarlet Red"), while Pigment Red 22 typically offers a bluish-red shade (often called "Bordeaux" or "Rubine"). PR21 is more cost-effective and widely used in general-purpose industrial applications, while PR22 is often preferred for higher-end printing inks and coatings requiring a cooler red tone.

Main applications include: *Coatings: Industrial paints, red baking enamels, latex paints, water-based paints, powder coatings, and decorative paints *Printing Inks: Offset inks, water-based inks, solvent-based inks, and composite inks *Plastics: PVC, LDPE, and general-purpose plastics (heat stability up to 160 degree) *Other: Leather, rubber, latex products, paper, textiles, stationery, printing ink pads, oil paints, watercolors, and cosmetics

Pigment Red 21 typically offers heat resistance in the range of 140-160 degree. This makes it suitable for medium-temperature applications such as PVC, LDPE, baking enamels, and general-purpose industrial coatings. For applications exceeding 160 degree, pigments with higher heat stability should be considered.

Pigment Red 21 is generally considered a safe industrial pigment. However, standard safety precautions apply: *Avoid inhalation of dust during handling. *Use appropriate PPE (dust mask, gloves) when handling in powder form. *Ensure adequate ventilation in processing areas. *Store in a cool, dry place away from moisture. *Not suitable for food contact applications unless specifically certified as food-grade.
