What are organic pigments?
Organic environmental protection pigment is a kind of organic environmental protection compound with bright color, strong tinting strength, non-toxic and colorful. Organic pigments are often used in the production of various products.
What are the advantages of organic pigments?
For example, dispersibility, environmental protection, and weather resistance are all very good. Today, let's talk about the dispersibility of organic pigments and let's see what role the dispersibility of organic pigments has in product applications~

Dispersibility refers to the ability of the pigment to evenly disperse in the product during the product coloring process. The dispersion state, particle size and distribution of organic pigments directly affect their application performance. Let's take a look at the role of the dispersibility of organic pigments in product applications~
1: tinting strength
The dispersibility of a pigment affects the tinting strength and shade. The coloring and covering of the product by the pigment are achieved through the complex effect of its surface and light. The pigment is well dispersed, the average particle size is small, the specific surface area is large, the effect on the light is strong, and the appearance of the colored product will appear uniform. , delicate, less stains, small color difference.
The better the dispersion of organic pigments, the higher their tinting strength and hiding power. The product can be quickly colored during the production process. If the dispersion of the pigment is not good and the coloring is uneven, streaks or color spots will easily occur, which will affect the appearance of the colored product and other properties of the colored product.
2: Cost
The dispersion of organic pigments is that the pigments break down the agglomerates of pigment particles under the action of external force. The amount of pigment can be reduced, so as to reduce the cost of coloring. It is very important to choose a high-quality organic pigment.
The price of organic pigments is generally more expensive than that of inorganic pigments, because of their bright colors, strong tinting strength, non-toxic and colorful characteristics. The cost will be higher. If an organic pigment has poor dispersibility, it will not achieve the effect of complete coloring and covering, and the cost will be higher.
3: Stability
When dispersing organic pigments, it is necessary to overcome the attraction between pigment molecules and disperse the pigment particles. The dispersed fine particles also need to remain stable to prevent them from re-agglomerating. Migration occurs, resulting in a splendid, uneven coloring of the product.
