Paint, painted in Chinese tradition as a paint. China's paint industry more authoritative "paint technology" a book is so defined: "paint is a material, this material can be used in different construction techniques coated on the surface of the object, the formation of strong adhesion, with a certain strength, continuous Solid film.

" Whether the traditional natural materials as raw materials of paint products, or modern development of synthetic chemical products as raw materials, paint products, are organic chemical polymer materials, the formation of the coating is a polymer compound type. In accordance with the classification of modern chemical products, paint is a fine chemical products.

To be painted three times in the middle of that time called halfway my explanation is not?
The middle coating is the abbreviation of the middle coating, that is, the coating between the primer and the finish, the equivalent of the filling layer, in order to increase the fullness of the paint.
