There are many classification methods for coatings, and there are usually the following classification methods: According to the form of intelligent products, they can be divided into: liquid coatings, powder coatings, and high-solid coatings. Dispersion medium used by paint: solvent-based paint; water-based paint (emulsion paint, additive paint).
According to the application, it can be divided into architectural coatings, can coatings, automotive coatings, aircraft coatings, home appliance coatings, wood coatings, pipeline coatings, plastic coatings, paper coatings, marine coatings, wind power coatings, nuclear power coatings, pipeline coatings, steel structure coatings, rubber Paint, aviation paint, etc.
According to its performance, it can be divided into: anti-corrosion coating, anti-rust coating, insulating coating, high temperature resistant coating, aging resistant coating, acid and alkali resistant coating, and chemical resistant coating. According to whether there is a color, it can be divided into: varnish and color paint. According to its construction process, it can be divided into: sealing paint, putty, primer, second primer, top coat, and finishing paint.
According to the construction method, it can be divided into brush coating, spray coating, roller coating, dip coating, electrophoretic coating, etc.
According to the function, it can be divided into non-stick coatings, Teflon coatings, decorative coatings, anti-corrosion coatings, conductive coatings, anti-rust coatings, high temperature resistant coatings, temperature indicating coatings, thermal insulation coatings, fireproof coatings, waterproof coatings, etc.
Household paint can be divided into interior wall paint, exterior wall paint, wood paint, metal paint, and floor paint.
According to paint film performance (anti-corrosion paint, insulating paint, conductive paint, heat-resistant paint...)
According to the film-forming substances (natural resin paint, phenolic paint, alkyd paint, amino paint, nitro paint, epoxy paint, chlorinated rubber paint, acrylic paint, polyurethane paint, silicone Resin paint, fluorocarbon resin paint, polysiloxane paint, vinyl resin paint...)
Classified according to the types of base materials: can be divided into organic coatings, inorganic coatings, organic-inorganic composite coatings. Organic coatings are divided into organic solvent-based coatings and organic water-based (including water emulsion and water-soluble) coatings due to the different solvents they use. Common paints in life are generally organic paints. Inorganic coatings refer to coatings produced with inorganic polymer materials as the base material, including nitride silicate series, silica sol series, organic silicon and inorganic polymer series. There are two types of organic-inorganic composite coatings. One is that organic materials and inorganic materials are used as base materials to form composite coatings during production; the other is that organic and inorganic coatings are combined during decorative construction.
Classified by decoration effect: can be divided into: 1. Flat coating with smooth surface (commonly known as flat coating), which is the most common construction method; 2. Sand wall-like paint with sand grain-like decorative effect on the surface, such as real stone paint; 3. Multi-layer paint with three-dimensional decorative effect of uneven patterns, such as relief. Classified according to the parts used on the building: divided into interior wall coatings, exterior wall coatings, floor coatings, door and window coatings and ceiling coatings.
Classified by function: It can be divided into ordinary paint and special functional architectural paint (such as fireproof paint, waterproof paint, anti-mildew paint, road marking paint, etc.). According to the color classification: such as metallic paint, natural paint (or called: solid paint), transparent varnish, etc.
