About composition of coating

The development of the modern coating industry is developing in the direction of functionalization, high decoration, environmental protection and low cost. 

Therefore, the coating formulation design must first grasp the development direction of modern coatings. Most coatings are composed of a binder (a resin or a mixture of several resins), pigments and fillers, solvents, and some small amounts of coating additives. 

Before designing the formula, you should first have a full understanding and understanding of each component of the coating and the raw materials used in each component. For example, the base material determines the basic performance of the coating; the pigment mainly gives the coating color and hiding power; the filler mainly gives the coating texture and reduces the cost; the solvent is used to dissolve the resin and adjust the construction performance such as the volatilization speed of the coating; coating additives can improve the production process, Keep storage stable, improve construction conditions, improve product quality, and endow special functions.
