Resin: Resin is the main component of the coating and determines the physical and chemical properties of the coating; 2. Pigment: The main component that provides the color and opacity of the coating; 3. Filler: Usually a colorless and white granular material, which increases the volume of the coating and reduces the cost; 4. Solvent: A liquid used to dissolve the resin and adjust the viscosity of the coating. There are many types of raw materials for coatings, which need to be weighed manually one by one. The amount of raw materials added cannot be accurately controlled, which will affect the performance of the coating. In the absence of weighing, the raw materials are easily wasted, which increases the cost. The coating will precipitate and stratify when not mixed, resulting in unevenness after the coating is stored for a long time, affecting the appearance and coating effect of the coating.
