The current situation of the powder coatings market and future technology trends

China Paint Online News News
In 2015, china's economy entered the new normal background, the domestic economy as a whole remained stable, while the economic downturn pressure increased, into the transition and upgrading stage, investment growth slowed down, supply and demand structure continued to optimize. Environmentally friendly coatings are in line with China's industrial structure policy, such as the "Industrial Structure Adjustment Guidance Directory" (2015) to environmentally friendly coatings as an incentive to develop industries. Powder coatings with environmental protection, energy saving, high performance and other characteristics, widely used in home appliances, furniture, real estate, automotive, infrastructure construction, 3C, anti-corrosion and other downstream industries, to meet its appearance, weather resistance, anti-corrosion and other performance of different requirements. Data show that in 2015, the cumulative production of paints nationwide was 17.1757 million tons, up 4.2% YoY, while the main business revenue was 418.484 billion yuan, up 7.30% YoY, of which the total production of powder coatings in China was 1.8335 million tons, up 8% YoY. At present, the domestic powder coating market is still dominated by small and medium-sized enterprises. Data from the top 20 companies in powder coating production in 2015 show that nearly half of enterprises' output showed a downward trend year-on-year in 2014.
powder coating technology is developed with the development of application market. The demand for powder coatings in different market areas is very large. Decades with the continuous expansion of the domestic application market, home appliance powder coatings, pipe anti-corrosion powder coatings, aluminum profile powder coatings, radiator powder coatings, anti-theft door powder coatings, highway guardrail powder coatings, insulation powder coatings and other products continue to emerge professional manufacturers, for China's powder coating technology to the high-end development of solid foundation. At the same time, the production equipment has made great progress, basically meet the needs of powder coating development. From the initial single screw development to double screw, and even multi-screw, from the lower screw speed level to a higher speed level, from the 10-wheeler to ACM grinding, are condensing the hard sweat of every worker. In addition, spraying equipment to meet the requirements of powder construction, the formation of a large number of specialized production of powder electrostectrectr From the beginning of all the introduction of foreign pipelines to the present spray line of localization, but also for the rapid development of powder coating laid a foundation.
powder coating technology development trend:
1) low temperature cured powder coating: powder coating is usually more demanding curing conditions, generally need to bake at 180 degrees C-200 degrees C for 10-15 minutes, baking temperature is higher, longer time, low efficiency, and low temperature cured powder coating baking temperature is about 150 degrees C. Reducing the curing temperature of powder coatings can not only speed up the production of automatic production lines and improve production efficiency, but also make powder coatings can be applied to composite materials, wood, plastics and other thermal substrates. Therefore, the realization of low temperature curing can effectively save energy, improve work efficiency and expand the application field, which is one of the important development directions of powder coating.
2) Thin coating powder coating: coating thickness is an important factor in determining the appearance of powder coating. At present, china's powder coating standard film thickness of 60-80 m, for some products that only need 30-40 m coating thickness, thick coating film performance surplus, increase costs. Therefore, thin coating is one of the important development directions of powder coating.
3) Powder coating for coils: With the increasingly stringent environmental requirements of the country and cost-effective factors, coil coating powdering will gradually be recognized by people, become the development trend of coil coating.
4) Functional powder coating: Functional powder coating refers to surface coating materials with special functions and special uses. It can not only play a traditional protective and decorative role, but also give materials a variety of special functions, such powder coating can be a fine structure with a matte color of high wear, scratch-resistant coating, can also be a rough surface structure, but the substation surface bump defects have a better masking performance of the coating. China's functional powder coating technology water than foreign advanced level still has a large gap, is one of the direction of future attack.
5) Art powder coating: Art powder coating is a special art decorative paint varieties. Fine art texture powder coating suitable for indoor and outdoor complex environments can mask substrate defects or enhance the image of the sprayed substrate. Fine art powder coating has higher performance requirements for the aesthetics, uniform stability and reproducibleness of pattern patterns.
6) Heavy anti-corrosion powder coatings: heavy anti-corrosion coatings to prevent corrosion-oriented, with excellent performance and acid resistance, alkali resistance, solvent resistance, heat resistance corrosion resistance, mainly used in oil pipelines, ships, construction rebar, storage tanks and so on.
7) Hydration powder coatings: Disperse powder coatings in water and add additives that are filtered to form a suspended liquid that has little effect on the performance of the final coating.
8) imitation plating effect powder: high imitation plating products on the powder production and use of very high requirements, a little negligence, will produce paint film defects. At present, Bonding technology, metal powder, powder appearance defects make imitation plating effect powder and the actual plating products still have a certain distance, but due to the increasingly stringent national environmental protection, environmental protection technology products will have a broader market space.
present, foreign powder coating production enterprises occupy 80% of China's high-end market share, domestic enterprises are mostly in the low-end market processing melee, even large powder coating enterprises and foreign enterprises there is a large gap. At present, the global powder coating market annual growth rate continues at about 8%-15%, powder coatings will become the mainstream direction of the coating industry, domestic powder coatings should seize the opportunity of national development, quickly open the market, promote the healthy development of the industry.
