Physical and Chemical Properties	hue or shade: brilliant yellow relative density: 1.43-1.45 Bulk density/(lb/gal):11.9-12.0 average particle size/μm:0.22 particle shape: small flake specific surface area/(m2/g):17-21 pH value/(10% slurry):7 oil absorption/(g/100g):86 hiding power: translucent reflex curve:
Use	This variety gives yellow-red color, which is mainly used for printing inks and coatings. In printing inks, the light fastness is grade 5-6, but the coloring power is slightly low, but the solvent resistance, acid/alkali, soap, sterilization treatment and other properties are good, heat-resistant 220 ℃/10min; Suitable for high-grade decorative coatings, the color light fastness is 7, non-transparent yellow red dosage form put on the market for the preparation of automotive coatings; in the polyolefin thermal stability is only 200 deg C, the scope of use is limited.

LogP	0.54 at 23℃ and pH7
