Use	There are 126 types of this product. Used for ink and paint coloring important varieties, green light yellow (between is C.I. Between pigment yellow 1 and pigment yellow 3), the coloring intensity is higher than that of the general monoazo pigment; More than C.I. Pigment Yellow 12 slightly red light, 1/3SD pigment yellow 12 need 4.5%, and pigment yellow 74 need 4.2%; There are different particle size varieties (specific surface area of 10-70m2/g, the specific surface area of Hansha yellow 5GX02 was 16 m2/g, and the large particle size dosage form (10-20 m2/g) showed high hiding power. Compared with the fine particle size variety, the non-transparent display is more red light, more light resistant, and the freshness is slightly lower, especially suitable for the coating industrial air self-drying paint, which can increase the concentration and further improve the hiding power without changing the rheological property, and can be used

Introduction

Pigment Yellow 74 is an organic pigment with the chemical name C.I. Pigment Yellow 74, also known as Azoic Coupling Component 17. The following is an introduction to the properties, uses, preparation methods and safety information of Pigment Yellow 74:

Quality:

- Pigment Yellow 74 is an orange-yellow powdery substance with good dyeing properties.

- It is less soluble in water but soluble in some organic solvents such as alcohols, ketones, and esters.

- The pigment is stable to light and heat.

Use:

- In plastic products, Pigment Yellow 74 can be used in injection molding, blow molding, extrusion and other processes to add to plastics to give them a specific yellow color.

Method:

- Pigment Yellow 74 is usually prepared by synthesis, which requires the use of a series of chemical reagents and catalysts.

- The specific steps of the preparation process include anilineation, coupling and dyeing, and finally the yellow pigment is obtained by precipitation filtration.

Safety Information:

- Pigment Yellow 74 is generally considered to be relatively safe under normal conditions of use.

- Proper handling should be followed when using this pigment, such as avoiding inhalation of the powder and avoiding contact with eyes and skin.

- In case of accidental inhalation or contact with the pigment, rinse immediately with clean water and consult a doctor for evaluation and treatment.
