What kinds of industrial paints are there and what are their characteristics?

When it comes to paint, the first thing we think of is the paint on the surface of furniture, and then the wall paint. Industrial paint refers to the paint mainly used in industrial production. Therefore, we know very little about it. So, what kinds of industrial paints are there? What are their characteristics?

Industrial paint is used for the protection and decoration of equipment, ships, containers, bridges, gas tanks, port machinery, chemical equipment, railway tank cars, motors, storage tanks, pipeline inner walls, various steel structures and concrete produced by industrial enterprises. At present, there are mainly the following industrial paints widely used: alkyd paint, amino paint, epoxy paint, polyurethane paint and acrylic paint, silicone paint fiber, fluorocarbon paint and so on.

alkyd paint

It is a kind of air-drying coating with good comprehensive performance, which is suitable for both brushing and spraying. This paint has excellent gloss, weatherability and elasticity, good gloss retention and adhesion, high solid content and good paint film fullness, but its disadvantages are long recoating time, strong solvent resistance, soft paint film and easy yellowing.

amino resin

Generally, it can't be used alone, and it is often used in combination with other coating resins. Amino alkyd coatings are more common.

The paint film is bright and flat, light in color, not easy to yellow, light-resistant, water-resistant, high in hardness, decorative and protective, but the flexibility of this paint is relatively poor. epoxy paint

Generally, it has excellent properties, including excellent adhesion, chemical resistance, corrosion resistance and water resistance, and good thermal stability. Disadvantages are poor weather resistance, easy powdering and poor paint film fullness.

polyurethane paint

Because of its unique chemical structure, it has many superior properties. First, the physical and mechanical properties are good, and the coating is hard, flexible, bright, plump, wear-resistant and has strong adhesion. Secondly, its coating has good oil resistance, acid resistance and chemical resistance, and has a wide range of applications, including one-component coatings and two-component coatings. However, many domestic polyurethane coating products contain more TDI free monomers harmful to human body, and the paint film is easy to yellow.

Fluorocarbon coating

It is the general name of a series of coatings with fluorine-containing resin as the main film-forming substance.

It is a new coating modified and processed on the basis of fluororesin. Its main feature is that the resin contains a large number of F-C bonds, and the bond energy is 485KJ/mol, ranking first among all chemical bonds. Under the action of heat and light (including ultraviolet rays), F-C is not easy to break, so it shows long-term weather resistance and chemical medium corrosion resistance, so its stability is the best among all resin coatings. This basically determines that it has better performance than other types of coatings, so it is known as the "king of coatings" in the industry. As a high-tech functional coating and a brand-new protective material for surface decoration, its weather resistance, chemical resistance and many other properties are superior to the popular high-grade coatings such as polyurethane, silicone and acrylic resin, and its outdoor service life is as long as 20 years. Fluorine resin has a series of varieties such as room temperature curing and low temperature baking, and has the ability of coating repair and regeneration. The construction method is basically the same as that of general coatings. Fluorine coatings have been widely used in construction, chemistry, electrical and electronic, machinery, aviation, aerospace, household items and other fields. According to relevant professionals, the biggest difference between industrial paint and household paint lies in the different environmental protection requirements, and there are also obvious differences in construction technology.
