Function and market prospect of powder coatings (1 of 4)

More and more coating users appreciate the advantages of powder coating, such as no pollution, stable storage, easy transportation, resource saving and high efficiency. With the support of demand, the types of powder coating are becoming more and more, with a wide range of applications. Powder coating can be seen from small-scale parts to the coating of various large-scale equipment. Shopping malls predict that by 2026, the scale of global powder coating shopping malls is expected to reach US $15 billion, with a compound annual growth rate of 6.8%.

It is worth noting that China's powder coatings mainly include epoxy, polyester and epoxy / polyester powder coatings. The proportion of high-grade acrylic, polyurethane and fluorocarbon powders is very small, less than 1%. Foreign funded production enterprises account for 80% of China's high-end powder coating shopping malls. Most domestic powder coating enterprises lack innovation and relatively backward technical level. The powder coatings produced are mainly general powder coatings. Now, there is a situation of oversupply in general powder coating shopping malls, the competition in shopping malls is aggravating, and the enterprises lacking central competitiveness are eliminated by shopping malls. This promotes the transformation and promotion of enterprises, focusing on high-end powder shopping malls and developing functional powder coatings with special functions to meet the appearance coating of specific uses.

Functional powder coatings refer to powder coatings that are suitable for specific occasions and have special functions. Based on the traditional protection and decoration effect, it gives the coating a variety of special properties, including insulation, anti-corrosion, waterproof, high temperature resistance, radiation protection and so on. According to the function, it can be divided into anti-corrosion, weather resistant, heat-resistant, hydrophobic and antibacterial powder coatings. With the development of powder coatings, new powder coatings such as anti mosquito and anti graffiti are emerging. Functional powder coatings cover all aspects of human life. For example, anti-corrosion powder coatings cover the fields of pipeline equipment, power equipment, highway transportation, marine equipment and military equipment. However, the development of functional powder coatings in China is relatively slow. Except for decoration type, anti-corrosion type and weather resistant powder coatings, other functional powder coatings are not developed. Based on this background, this paper mainly introduces six functional powder coatings: heavy-duty anti-corrosion powder coating, weather resistant powder coating, antibacterial powder coating, high-temperature resistant powder coating, hydrophobic powder coating and self-healing powder coating.

Heavy duty anticorrosive powder coating

Every year, the direct loss caused by corrosion accounts for about 2% ~ 4% of GDP, and the damage exceeds the total loss of natural disasters and various incidents. In order to avoid the corrosion of parts, people choose to apply anti-corrosion coating on the surface to block the touch between the data and the external environment, protect the metal data inside the coating and ensure the long-term use of parts.

According to the data, anticorrosive coatings are divided into general anticorrosive coatings and heavy anticorrosive coatings: General anticorrosive coatings with a service life of 5 ~ 10 years; Compared with general anti-corrosion coatings, heavy-duty anti-corrosion coatings have good adhesion, resistance to the penetration of corrosive media, or chemical resistance to corrosive media, and the film itself has strong durability, so as to provide corrosion resistance for the coated materials. The service life can reach more than 30 years, and the anti-corrosion effect can be improved by 4 ~ 5 times. Common anti-corrosion powder coatings are divided into general modified anti-corrosion coatings, fusion bonded epoxy powder coatings and epoxy zinc rich powder coatings.
