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. |
Introduction
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.
