Pigment Red 8 CAS#6410-30-6

Pigment Red 8, also known as Permanent Red F4R, has a CAS number of 6410-30-6. The following are some of its properties and related information:
Physical indicators: Light resistance: Level 5 Heat resistance: 140℃ Acid resistance: Level 4 Alkali resistance: Level 4
Product parameters: Density (g/ml, 25/4℃): 1.45～1.65 Oil absorption: ≤55g/100g
Specific surface area /(m²/g): 50-60 Hiding power: Transparent pH value: 6.5-7.5
Pigment performance: It is a bright blue-red pigment, belonging to the monoazochromophore as pigment. It has brighter color, stronger tinting power, better light resistance and saponification resistance, but weaker solvent resistance. When used for coloring printing ink, it is easy to recrystallize in packaging ink, affecting color strength and transparency. However, it is sensitive to varnish and sterilization treatment, and is heat-resistant to 140℃/3min. It can also be used for fabric printing with low light fastness requirements.
Application areas: Mainly used for coloring ink, paper, varnished cloth, cosmetics, oil paint, pencil, model clay and sealing wax, etc., and can also be used for coloring artificial leather, rubber and plastic products.
Upstream raw materials: scarlet base G, emulsified oil, color phenol as-E, caustic soda, sodium nitrite, hydrochloric acid, etc.
