Introduction

Pigment Yellow 81 (CAS 22094-93-5) is strong greenish yellow, similar to the monoazo pigment CI Pigment Yellow 3. It has satisfactory light fastness, good heat and solvent resistance, and is suitable for solvent-containing metal decorative inks; in alkyd trimerization The light fastness of the nitrile amine coating is 6-7; it is more heat-resistant than other benzidine yellow varieties; polyolefin (260℃/5min), the coloring of soft PVC bleeds at low concentrations, and hard PVC (1/ 3SD) Light fastness is grade 7; it can also be used for the coloring of cellulose acetate pulp and pigment printing paste.

Best Sellings

PY81 – DuraPlast®3181-1 ⬇️TDS

In plastics application, P.Y.81 is very resistant to bleeding, provided the appropriate concentration limits are observed. Its heat resistance makes it a useful colorant for polyolefins.
