Solvent: Adjust the viscosity to prevent drying in the water-based color paste system. Resin: As a carrier, it is generally not necessary to use in water-based color paste systems. Defoamer: In water-based color paste systems, it can avoid foaming during grinding and filling. Anti-settling agent: prevent pigment settling.
Pigment: Provides color and hiding power, divided into organic/inorganic pigments according to the needs of finished paint.
Others: such as preservatives, etc.

The pigments, resins and dispersants are introduced in more detail below.
Pigments are an important part of the color paste, and they must be strictly selected wax emulsion michelman according to the final application. The main points worth considering are: hue vividness, weather resistance, color strength and price.
In the integrated toning system, special attention should be paid to the narrow range of pigment specifications (such as color intensity), in order to avoid problems caused by quality fluctuations in the integrated toning of the color paste.

Surface area of ​​the pigment
In order to stabilize the pigments used in paints and color pastes, a dispersant is added. The necessary pigments, resins and dispersants are introduced in more detail below.
