Fast Yellow G CAS#2512-29-0

1. Physical and chemical properties
Appearance: yellow powder.
Density: generally between 1.3 – 1.5 g/cm³.
Solubility: insoluble in water, but has certain solubility in some organic solvents.
Stability: has good thermal stability and light resistance. The color is relatively stable within a certain temperature range, and it is not easy to decompose and discolor due to heat; at the same time, it can maintain good color durability under light.
2. Uses
Paint field: can be used in various types of coatings, such as architectural coatings, industrial coatings, automotive coatings, etc. Provide a bright yellow hue for the coating and enhance the decorative effect of the coating.
Ink field: suitable for printing inks, including offset inks, gravure inks, flexographic inks, etc. It can make the printed matter appear bright yellow and improve the visual appeal of the printed matter.
