Paints, as surface covering materials widely used in various fields, have many types and different functions. From home decoration to industrial applications, from architectural exteriors to automotive manufacturing, paints play an integral role. 

The following is a detailed introduction to classifying paints to take you through the richness and variety of the world of paints.

1. Classification by main film-forming substances
Oil-based paint: Use dry oil as the main film-forming substance, such as paint. This type of paint has bright colors and good decorative properties, but has poor weather resistance and water resistance.

Water-based paint: uses water-soluble resin as the main film-forming substance, such as latex paint. Water-based coatings are environmentally friendly, pollution-free, and easy to construct, but their weather resistance and water resistance need to be improved.

Powder coating: solid powder is the main film-forming substance, such as epoxy resin powder coating. Powder coating has the advantages of no pollution, high decorativeness, and high weather resistance, but the construction cost is high.

2. Classification by use

Architectural coatings: used for coating interior and exterior walls, floors, ceilings, etc. of buildings, such as interior and exterior wall latex paints, waterproof coatings, etc. Architectural coatings are required to have good decorative properties, weather resistance and water resistance.

Industrial coatings: used for coating mechanical equipment, pipelines, bridges and other industrial fields, such as anti-corrosion coatings, high temperature resistant coatings, etc. Industrial coatings require excellent corrosion resistance, abrasion resistance and weather resistance.

Automotive coatings: used for car surface coating, such as primer, topcoat, etc. Automotive coatings require excellent weather resistance, scratch resistance and decorative properties.

3. Classification by function

Decorative coatings: mainly used to beautify the surface of objects, such as latex paint, wallpaper, etc. Decorative paint requires rich colors and good decorative properties.

Protective coating: used to protect objects from erosion by the external environment, such as anti-corrosion coatings, anti-rust coatings, etc. Protective coatings require excellent corrosion resistance and weather resistance.

Special function coatings: coatings with special functions, such as fire retardant coatings, conductive coatings, heat-insulating coatings, etc. Special functional coatings require specific properties to meet special application requirements.

4. Classification according to construction methods

Spray coating: Spray coating on the surface of objects through spray equipment, suitable for large-area, high-efficiency construction.

Brushing paint: Use a brush to apply paint on the surface of an object, suitable for construction on small areas or complex surfaces.

Roller coating: Use a roller to apply paint to the surface of an object, suitable for construction on flat surfaces.

5. Classification according to curing method

Solvent volatilization cured coatings: Coatings, such as paint, are cured by solvent evaporation.

Thermal Curing Coatings: Coatings that are cured by heating, such as epoxy resin coatings.

UV curing coating: Use ultraviolet irradiation to quickly cure the coating, suitable for high-efficiency production lines.

In short, there are many types of coatings, each with its own unique properties and uses. When selecting coatings, you need to choose according to specific application requirements and construction conditions to ensure the coating effect and object performance.
