Coatings, what we usually call paint is just one of them. Refers to a type of liquid or solid material that is applied to the surface of an object to form a thin film under certain conditions to protect, decorate or otherwise perform special functions (insulation, rust prevention, mildew proofing, heat resistance, etc.). Solvent-based paint is a kind of volatile paint formulated with macromolecule synthetic resin as main film-forming substance, organic solvent as diluent, a certain amount of pigments, fillers and auxiliaries, mixed, stirred and dissolved, and ground. After brushing on the outer wall, the film-forming substance and other non-volatile components together form a continuous and continuous thin film, ie coating, as the solvent contained in the paint volatilizes. Due to the tightness of the coating, it usually has good hardness, gloss, water resistance, acid and alkali resistance, good weather resistance, and pollution resistance. However, due to the volatilization of organic solvents that are easily tolerated during construction, it is easy to pollute the environment.

The film has poor air permeability and hydrophobicity. If it is applied on a wet grass floor, it can easily cause peeling and peeling. For these reasons, the amount of such exterior paints at home and abroad is lower than that of emulsion-type exterior wall paints. The solvent-based acrylic exterior wall coatings developed in recent years have outstanding weather resistance and decorative properties. The durability period is more than 10 years. The construction period is also short and can be used at lower temperatures. Overseas weather resistance and water resistance are very good, and it has a high elasticity polyurethane exterior wall coating. The durability period can reach more than 15 years.
