Pigments is an important ingredient of coatings. The most important role of pigments is making  the coating colorful. In addition, it can protect and improve the  mechanical properties of coatings. When choosing pigments, paint manufacturers should mainly focus on the following properties of pigments:
1.The particle size directly affects the hiding power and tinting power of the pigment. The smaller of the particle, the better of the dispersion, and the greater the hiding power. For most pigments. The smaller the particles, the greater the tinting power.

2. The shape of the pigment particles. The shape of the pigment particles mainly affects the fluidity, storage and durability of the paint.

3.Surface area of ​​pigment particles. The specific surface area of ​​a particle is defined as the surface area per unit mass of pigment. It is inversely proportional to particle size. When the mass of the pigment particles remains constant, the particle size is reduced by half and the surface area is doubled.

4.Surface treatment of raw material particles. With appropriate treatment, the surface of the pigment particles is either modified or completely replaced by a new surface.

5.Particle size distribution of pigment particles. Pigment is a solid particle, regardless of the manufacturing process. It cannot be composed of one particle size, but has a certain distribution range.

    Over the past 20 years, Yuhong Pigment has specialized in the production and research of organic pigments. The organic pigment  are stable in performance, easy to disperse. We have various types of pigments for coatings with high cost performance.
