There are various types of furniture coatings, which can be classified into multiple types according to different classification standards. Here are some common classification methods:
1. Classified by solvent type
Water based paint: Using water as a solvent, it has good environmental performance and is currently the main product in the paint market. Water based paint can be divided into initial products (using acrylic acid as the film-forming substance, with poor wear resistance and chemical resistance), intermediate products (mainly composed of a composite of acrylic acid and polyurethane, which enhances wear resistance and chemical resistance), and high-end products (polyurethane water-based wood paint, with film comprehensive performance basically equal to ordinary oil-based paint).
Oil based paint: Using organic solvents as dispersing agents, the paint film has good performance, but relatively poor environmental performance. Oil paint includes various types such as nitro paint, alkyd paint, polyurethane paint, polyester paint, etc.
2. Classified by solidification method
UV paint (UV cured wood paint): It is automatically rolled, sprayed, and sprayed onto furniture surfaces by machine equipment, and instantly cured into a film under UV light irradiation. UV paint has the advantages of environmental protection, high efficiency, high hardness, and good transparency, but the equipment cost is high and it cannot be applied to irregular objects.
3. Classified by film-forming substance
Nitro lacquer: divided into two types: nitro clear varnish and nitro solid paint, mainly used for transparent and opaque coating of furniture. Nitro lacquer has the advantages of high hardness, wear resistance, and water resistance, but the construction process is complex and the heat and cold resistance are not high.
Alkyd paint: mainly used for painting indoor furniture, it has the advantages of good glossiness, durability, and insulation, but it dries slowly, is not water-resistant, and cannot be polished.
Polyurethane paint: It has the advantages of good wear resistance, strong adhesion, solvent resistance, cold resistance, etc., but it dries slowly and has poor color retention performance.
Polyester paint: The paint film is full and thick, with good gloss retention, high transparency, wear resistance, gloss retention, and high heat resistance, cold resistance, and temperature resistance. However, the adhesion is poor and cannot withstand too much impact force.
Acrylic resin paint: belongs to high-end paint, with advantages such as color paint, UV resistance, good heat resistance, hardness, and easy construction, but the paint film is brittle and the cold resistance is poor.
