Pigment Red PR81 Structure

Who is iSuoChem: China Red P.R.81 Supplier/Exporter/Factory/Manufacturer/Solution provider.

Although organic pigment red 81 exhibits limited resistance to polar solvents (such as alcohols, ketones, and esters), it exhibits excellent stability to aliphatic and aromatic hydrocarbons, paraffin waxes, and oils. However, it is not autoclave-resistant. This pigment is irreplaceable in the printing industry. Its unique bluish-red hue cannot be reproduced by other pigments, making it a key choice for three- and four-color printing.

C.I.P.R.81 Red - Key Applications

Printing Inks: Offset and letterpress printing, particularly suitable for the "Process Red" standard in four-color printing.

Industrial Coatings: Red 81 pigment is suitable for coatings requiring vibrant red-purple tones, but avoiding polar solvent environments.

Plastics and Rubber: Pigment red 81 provides bright coloration and is suitable for non-high-temperature processing.

Textile Printing: Water-based or solvent-based inks produce fluorescent effects.

Packaging Printing: Resistant to fats and waxes, suitable for food packaging (non-sterile conditions).

This versatility makes PR81 red pigment a classic red pigment in the printing and industrial sectors, but solvent restrictions and application environments must be considered.
