Product Description of Pigment Yellow 74:

An important pigment for the coloring of inks and coatings, greening shade (between CI Pigment Yellow 1 and Pigment Yellow 3), the coloring strength is higher than general monoazo pigments; slightly reddish than CI Pigment Yellow 12, 1/ Pigment Yellow 12 requires 4.5% under 3SD, and Pigment Yellow 74 requires 4.2%; there are varieties with different particle sizes (specific surface area is 10-70m2/g, of which Hansa Yellow 5GX02 specific surface area is 16m2/g), large particle size dosage form (10-20m2/g) shows high hiding power. Compared with fine-grained varieties, non-transparent displays are more reddish, more light-resistant, and have a slightly lower vividness. It is especially suitable for coating industrial air-drying paints. It can increase the concentration to further improve the hiding power without changing the rheology.

Pigment Yellow 74 is an organic pigment. It is a mono azo pigment powder, with greenish yellow color, and it has a redder tint than pigment yellow 12. It offers good color strength, and good dispersion and lower viscosity. It is good use in a wide variety of applications including plastics, paints, printing inks. This product is especially good for coating industry air-drying paints.
