Any paint that USES water as a solvent or as a dispersing medium can be called waterborne coating. Water paint brands on the basis of binder in the coating category, waterborne coatings is divided into two categories: natural substances or natural minerals such as potassium silicate coating, such as acrylic resin and synthetic resin petrochemical water-based paint. In this paper, only water - based coatings of synthetic resins are described.

    Waterborne coatings include water-soluble coatings, water-diluting coatings and water-dispersing coatings (latex coatings). Water soluble coatings based on water soluble resin as film forming matter, represented by polyvinyl alcohol and its various modification, there are water soluble alkyd resin, water soluble epoxy resin and inorganic polymer water-based resin, etc.

    Waterborne coatings can solve problems

    1, because of the water-based coating with water as the main solvent, so made a great contribution on environmental protection, not much affect not only to the human body, for enterprises in the production process, also reduced the pollution emissions.

    2, for oily coating in the coating is a little sticky feeling on the process, but there is no such worries for coating, coating process would be a good liquidity, process will be more convenient.

    3. In addition, water-based coatings will be thinner and denser than oil coatings, with water as the solvent, and the coating effect will be more even.

    Waterborne coatings can also be divided according to the types of resins, such as water-borne alkyd coatings, water-borne epoxy coatings, water-borne acrylic coatings, water-borne polyurethane coatings and so on. Waterborne coatings can also be divided into anionic waterborne coatings, cation waterborne coatings and non-ionic waterborne coatings. Water-based coating way of coating can be divided into electrophoresis coating, since swimming paint, water-based paint, water-based roller coating spray paint, water-based paint, etc., can be divided into the cathodic electrophoretic coating and electrophoretic coating anode electrophoresis coatings. According to the packaging category, there are single component waterborne coatings and two-component waterborne coatings. Obviously, the single component here is not a component, but refers to the form of packaging, more accurate should be called single packaging and double packaging. According to the purpose of classification, waterborne building coatings and waterborne industrial coatings. Water-based industrial coatings can be divided into water-based furniture coatings, water-based metal coatings, water-based automobile coatings, water-based plastic coatings and so on.
