A Acrylic Emulsion Paint: Acrylic emulsion paint is generally composed of acrylic emulsion, pigments and fillers, water, and additives. It has advantages such as moderate cost, excellent weather resistance, good adjustable performance, and no release of organic solvents. It is a rapidly developing type of coating product recently. It is mainly used for interior and exterior wall coatings of buildings, leather coatings, etc. Recently, new varieties such as wood lacquer and self-crosslinking emulsion paint have appeared. Acrylic emulsion paint can be divided into pure acrylic, styrene-acrylic, silicone-acrylic, vinyl acetate-acrylic, and other types based on different emulsions.

B Solvent-based Acrylic Paint: Solvent-based acrylic paint has excellent weather resistance and very high mechanical properties, making it a rapidly developing type of coating. Solvent-based acrylic paint can be divided into air-drying acrylic paint (thermoplastic) and crosslinking curing acrylic paint (thermosetting). The former belongs to non-conversion coatings, while the latter belongs to conversion coatings. Air-drying acrylic coatings are mainly used in architectural coatings, plastic coatings, electronic coatings, road marking coatings, etc., with advantages such as quick surface drying, easy application, and obvious protective and decorative effects. The disadvantages are that the solid content is not easy to be very high, hardness and elasticity are difficult to balance, a thick film cannot be obtained in one application, and the film fullness is not ideal. Crosslinking curing acrylic coatings mainly include acrylic amino paints, acrylic polyurethane paints, acrylic alkyd paints, radiation curing acrylic coatings, and others. They are widely used in automotive coatings, electrical coatings, wood coatings, architectural coatings, and more. Crosslinking curing acrylic coatings generally have very high solid content, can achieve thick films in one application, have excellent mechanical properties, and can be made into coatings with high weather resistance, high fullness, high elasticity, and high hardness. The disadvantages are that they are two-component coatings, application is relatively complicated, many varieties require heating curing or radiation curing, have high environmental requirements, and generally require good equipment and skilled application techniques.

C Polyurethane Paint: Polyurethane coatings are currently a common type of coating and can be divided into two-component polyurethane coatings and single-component polyurethane coatings. Two-component polyurethane coatings generally consist of isocyanate prepolymers (also called low molecular weight carbamate polymers) and hydroxyl-containing resins, usually referred to as curing agent component and main agent component. There are many varieties of this type of coating with a wide range of applications. Based on the hydroxyl component, they can be divided into acrylic polyurethane, alkyd polyurethane, polyester polyurethane, polyether polyurethane, epoxy polyurethane, and other types. They generally have good mechanical properties, high solid content, and good overall performance. They are a promising type of coating. Main applications include wood coatings, automotive repair coatings, anti-corrosion coatings, floor coatings, electronic coatings, and special coatings. The disadvantage is that the application process is complex, requires high environmental conditions, and the paint film is prone to defects. Single-component polyurethane coatings mainly include urethane oil coatings, moisture-curing polyurethane coatings, and sealed polyurethane coatings. Their application range is not as broad as two-component coatings and is mainly used for floor coatings, anti-corrosion coatings, and pre-coated materials. Their overall performance is not as comprehensive as two-component coatings.

D Nitrocellulose Paint: Nitrocellulose paint is a relatively common coating for wood and decoration. Its advantages are good decorative effect, simple application, quick drying, low environmental requirements for coating, good hardness and gloss, less prone to film defects, and easy repair. The disadvantages are low solid content, requiring multiple coats to achieve good results; poor durability, especially for interior nitrocellulose paint, which has poor gloss and color retention, and tends to show defects such as dullness, cracking, and discoloration after a short period; poor film protection, not resistant to organic solvents, heat, or corrosion. The main film-forming materials of nitrocellulose paint are mainly nitrocellulose, combined with alkyd resin, modified rosin resin, acrylic resin, amino resin, and other soft and hard resins. Plasticizers such as dibutyl phthalate, dioctyl phthalate, and oxidized castor oil are generally added. Solvents mainly include esters, ketones, alcohol ethers as true solvents, alcohols as co-solvents, and benzene as diluents. Nitrocellulose paint is mainly used for wood and furniture coatings, home decoration, general decorative coatings, metal coatings, and general cement coatings.

E Epoxy Paint: Epoxy paint is a rapidly developing type of industrial coating in recent years. Generally, coatings containing a high amount of epoxy groups are collectively called epoxy paints. The main types of epoxy paint are two-component coatings composed of epoxy resin and curing agent. There are also some single-component air-drying types, but their performance is somewhat inferior to two-component coatings. The main advantages of epoxy paint are strong adhesion to inorganic materials such as cement and metal; excellent corrosion resistance; excellent mechanical properties, wear resistance, and impact resistance; can be made into solvent-free or high solid content coatings; resistant to organic solvents, heat, and water; and non-toxic film. The disadvantages are poor weather resistance, with possible chalking after prolonged sunlight exposure, so it can only be used as primer or interior paint; poor decorative effect, gloss is hard to maintain; high requirements for application environment, slow film curing at low temperatures with poor results; many types require high-temperature curing and large investment in coating equipment. Epoxy resin coatings are mainly used for floor coatings, automotive primers, metal anti-corrosion, and chemical anti-corrosion.

F Amino Paint: Amino paint mainly consists of two parts: one is the amino resin component, mainly including butylated melamine-formaldehyde resin, methylated melamine-formaldehyde resin, butylated urea-formaldehyde resin, and other resins; the other is the hydroxyl resin part, mainly including medium-short oil alkyd resin, hydroxy-containing acrylic resin, epoxy resin, and other resins. Except for urea-formaldehyde resin paint used in wood coatings (commonly called acid-cured paint), most varieties require heat curing, generally at temperatures above 100°C and curing times over 20 minutes. The cured film has excellent performance, being hard, full, bright, beautiful, firm, durable, with good decorative and protective effects. The disadvantages are high requirements for coating equipment, high energy consumption, and unsuitability for small-scale production. Amino paint is mainly used for automotive topcoats, furniture coatings, household appliance coatings, various metal surface coatings, instrument and industrial equipment coatings.

G Alkyd Paint: Alkyd paint is mainly composed of alkyd resin. It is currently the most produced type of coating domestically. It has advantages such as low cost, easy application, low environmental requirements during application, full and hard paint film, good durability and weather resistance, as well as good decorative and protective properties. The disadvantages are slower drying, the paint film is not easy to meet high standards, and it is not suitable for highly decorative occasions. Alkyd paint is mainly used for general woodwork, furniture, and home decoration coatings, general metal decorative coatings, metal anticorrosion coatings with low requirements, general agricultural machinery, automobiles, instruments, and industrial equipment coatings.

H Unsaturated Polyester Paint: Unsaturated polyester paint is also a rapidly developing type of coating recently, divided into air-drying unsaturated polyester and radiation curing (photo-curing) unsaturated polyester. The main advantages are that it can be made into solvent-free coatings, a single application can achieve a relatively thick paint film, the coating temperature requirements are not high, and the paint film has good decorative effects, toughness, wear resistance, and is easy to maintain. The disadvantages are that the paint film shrinks significantly during curing, adhesion to the substrate can be problematic, air-drying unsaturated polyester generally requires polishing, which is cumbersome, and radiation curing unsaturated polyester requires high coating equipment standards, making it unsuitable for small-scale production. Unsaturated polyester paint is mainly used in furniture, wooden flooring, and metal anticorrosion.

I Vinyl Paint: Vinyl paint includes varieties such as chlorinated vinyl copolymer resin paint, polyvinyl butyral paint, vinylidene chloride, perchloroethylene, and chlorosulfonated polyethylene paint. The main advantages of vinyl paint are weather resistance, chemical corrosion resistance, water resistance, insulation, mildew resistance, and good flexibility. Its disadvantages mainly lie in average heat resistance, difficulty in producing high-solid coatings, average mechanical properties, and poor decorative performance. Vinyl paint is mainly used in industrial anticorrosion coatings, electrical insulation coatings, phosphating primers, metal coatings, and exterior coatings.

J Phenolic Paint: Phenolic resin is a product formed by the condensation of phenol and aldehyde in the presence of a catalyst. In the coating industry, oil-soluble phenolic resin is mainly used for paint production. The advantages of phenolic paint are fast drying, glossy and hard paint film, good water resistance, and good chemical corrosion resistance. The disadvantages are easy yellowing, not suitable for making light-colored paints, and poor weather resistance. Phenolic paint is mainly used in anticorrosive coatings, insulating coatings, general metal coatings, and general decorative coatings.
