Application of photoinitiator and UV coatings in bamboo, wood and plastics

Compared with traditional solvent-based thermal curing technology, UV light curing technology has many advantages such as fast curing speed, instant film forming, no volatile solvent, small environmental pollution, high safety, low energy consumption, small footprint, compact design, suitable for assembly line operation, low production cost, excellent coating performance and so on.

Photoinitiator is the key material in the photocuring system, which is formulated with active diluent, oligomer, auxiliaries and other raw materials, and then applied to the end user. Although the amount of photoinitiator is small, it plays an important role in the photocuring system.

At present, the main application fields of photoinitiator downstream are PCB inks, UV coatings and microelectronics industry, in which the output of UV coatings is rising year by year. In 2018, the output of UV coatings in China reached 107,800 tons, with a year-on-year growth of 21.1%.

At present, UV coatings in China are mainly used in bamboo and plastic, that is, in the field of wood coatings, packaging coatings more applications. UV coatings are rarely used in optical fiber coatings for industrial maintenance and protection.

The application of UV coatings has not really covered the large amount of coating architectural decorative coatings field. Therefore, the international UV coating production accounted for the total production of paint average level of 2.8%-3.2%, and China's development is more late, in recent years accounted for only 0.4-0.6%.
