Applications of 81-77-6
| Industry | Application | Process |
|---|---|---|
| Inks | Provides vibrant blue shade in offset, gravure, and flexographic inks | Formulated into solvent-based or water-based inks by grinding and dispersing the pigment into the vehicle |
| Coatings | Used for coloring industrial coatings, automotive coatings, and powder coatings | High-speed dispersion in resin systems, followed by grinding to produce color pastes or direct incorporation into coating bases |
| Plastics | Used for coloring plastic products such as polyolefins (e.g., PP, PE), ABS, and PS | Premixed with polymer granules prior to extrusion pelletizing or injection molding; thermally stable up to typical processing temperatures (≤300°C) |
| Textiles | Used for solution dyeing or dyeing of polyester and polyester-blend fabrics | Applied via high-temperature, high-pressure dyeing or carrier dyeing; also suitable for spun-dyeing (solution dyeing) |
| Artist Pigments | Provides stable blue hue in premium artist paints (e.g., oil and acrylic paints) | Ground to specified fineness, then mixed with drying oils or acrylic emulsions to produce finished paint |
