What is the difference between the pigment and the pigment in the paint?
Pigments and physical pigments are special solids that are dispersed in the paint to impart certain properties to the paint. These properties include color, hiding power, durability, mechanical strength, and corrosion resistance to metal substrates. Among them, the pigment is mainly for the adhesive to provide color and hiding power, but also need to meet the mechanical strength and corrosion resistance and other requirements. Pigments can be divided into two kinds of inorganic pigments and organic pigments. In the paint formulations, mainly the use of inorganic pigments, and organic pigments used for decorative coatings. Most of the body pigments are white powder, no actual function (color strength or hiding power), but has increased the thickness of the film, improve the durability of the film and reduce costs and so on. Color, color fastness, tinting power and hiding power are inherent properties of pigments, which are related to the structure and composition of pigments. The crystal morphology, particle size and shape of the paint on the luster, paint storage during the stability of the pigment and the base material on the wetting of the pigment surface have a greater impact. In the paint industry, the use of grinding or high-speed dispersion method is usually used to disperse the pigment evenly in the paint system and keep it in a suspended state or easily dispersed after settling. Therefore, the paint is concerned, the pigment is a very important auxiliary material.
