2.Application CharacteristicsPrimary Applications:
Printing Inks: Widely used in flexographic and gravure inks for packaging, particularly where very high brightness and cleanliness of shade are required. Common in poster and magazine printing.
Plastics: Limited to low-temperature processing plastics like PVC and LDPE. Its poor heat resistance restricts use in engineering plastics.
Coatings: Used in indoor decorative paints and industrial finishes where maximum brightness is needed and lightfastness is not critical.
Office & Stationery: Ideal for coloring pencils, crayons, and stamp pad inks due to its brilliant shade.
Key Advantages:
Exceptionally bright, clean, and intense bluish-red (pink) shade.
High tinting strength.
Can exhibit fluorescence, providing very high visibility.
