Physical and Chemical Properties | solubility: it is purplish red in concentrated sulfuric acid, and blue-red precipitation after dilution. hue or shade: brilliant yellow relative density: 1.40-2.09 Bulk density/(lb/gal):12.4-17.4 average particle size/μm:0.07-0.08 particle shape: small flake specific surface area/(m2/g):36-41 pH value/(10% slurry):6.5-9.0 oil absorption/(g/100g):25-60 hiding power: translucent reflection curve: This product is yellow red powder, strong coloring, insoluble in water and ethanol, and changes to purple red and brown red when dissolved in concentrated sulfuric acid and concentrated nitric acid, respectively. Good heat and heat resistance. |
Use | barium salt lakes, which give a bright yellow light to neutral red, 57:1 more than pigment red, are clearly yellow light, have good solvent resistance, but are inferior to soap, acid/alkalinity. Mainly used in gravure printing ink and plastic, in the soft PVC, good migration resistance, no frost, light resistance to grade 3, in the PE heat resistance 200-240 ℃/5min; Can also be used for non-high-grade coatings, good resist finish paint, light resistance grade 5-6. There are 66 brands of goods in the market. It is mainly used for the coloring of ink, plastic, rubber, paint and cultural materials. |

EPA chemical information | C. I. Pigment Red 48, barium salt (1:1) (7585-41-3) |
pigment red 48:1(Pigment Red 48:1), barium salt lake, giving bright yellow light to neutral red, obvious yellow light than pigment red 57:1, good solvent resistance, but poor for soap and acid/basicity. It is mainly used in gravure printing ink and plastic. It has good migration resistance in soft PVC, no frost spraying, light resistance of grade 3, and heat resistance of 200-240 ℃/5min in PE. It can also be used for non-high-grade coatings, with good gloss-resistant paint and light-resistant grade 5-6.
