Paint, usually called "paint". It is based on resin or oil, with or without pigments and fillers, prepared with a dispersion medium (organic solvent, water, etc.), coated on the surface of the protected and decorated object, and can form a firm adhesion A continuous film of viscous liquid or solid powder.
In the past, because paints were made of vegetable oil and natural resins, and their functions were similar to those of raw lacquers in my country, they were always called "paints". With the development of petrochemical and organic synthesis industries, the paint industry has added new sources of raw materials, and many new paints no longer use vegetable oils. The proportion of vegetable oil in the raw materials of paint production is gradually decreasing, and new varieties with various functions are increasing day by day, so that the appearance of paint products has undergone fundamental changes. In the past, varieties based on vegetable oils, natural resins and other natural products have been gradually replaced by varieties based on synthetic materials. Now using the word "paint" to collectively refer to this kind of products can no longer properly show their true features. From the perspective of their efficacy, it should be called "paint" more appropriately. Therefore, now we have officially adopted the name "paint", but due to people's long-term habits, sometimes paint is still referred to as paint. New and used products of paints and coatings.
