UV coating
UV coating is the most important UV curable formulations. Major domestic production enterprises in Shunde Heygey Chemical Company, Dongguan Wang Tak Chemical Company, Hunan this Anya Daxin Materials, Suzhou Ming Polymer Technology Materials, Inc., Heng paint (Huiyang) Ltd., Hunan Jinhai Chemical Company, Guangdong, China Resources Coatings Company, Guangzhou Wang Yu paint company, Jiang Yin Yuwei Polymer Chemical Company, Nanjing peaceful Xin Chemical, Panyu Pearl Chemical Corporation. 2005 total production of various UV coating 25024t, 2.2 times that of 2000; production value of 914.07 million yuan, 2.2 times that of 2000; exports 2270t, earning $ 10 million. The main products UV wood and furniture coatings production 13543t, UV Varnish on paper 5812t, uv plastic coatings 2342t, UV-PVC coating 1757t, UV motorcycle paint 666t, UV Appliance Paint 322t, UV coatings for handset 281t, optical coatings 100t.
UV inks
UV inks, including printing inks and the printed circuit board with a variety of UV inks. Major domestic production enterprises Hangzhou China ink chemical company, Shenzhen Miramar ink coating company, Zhejiang Mino ink coating company, Panyu Pearl Chemical Company, Zhongshan benefits of ink coating company, Panyu Guangdong International Trust and screen printing materials company, capacity of Shenzhen Electronic Materials company, Fuji-based research (Kunshan) Co., Beijing, Rio Tinto Technology Corporation. 2005 UV inks output reached 11039t, 5.3 times that of 2000; output value of 831.28 million yuan, 4.3 times that of 2000; export 253t, earning more than 200 million U.S. dollars.

DVD with UV adhesives which yield 200t, UV adhesives gear 46t, UV adhesives crafts 45t, UV optics and glass binder 45t, Medical UV adhesives 13t, LCD and instrument UV adhesives 11t.
UV equipment
Such as UV energy meter, UV intensity meter and other manufactured with the use of UV-related equipment, related technology from abroad in recent years, the development of many well-known domestic enterprises, the Shenzhen Municipal Bureau of speed technology company that was founded in 2007 in which a , is engaged in production and sales of UV equipment, UV equipment and service integration professional company focused to provide customers with the most reliable quality, outstanding high-tech products, but can contract instrument maintenance, calibration, and other services. There are several other related not introduced.
In China Photographic Society of Professional Committee of Statistics of radiation curing 122 production enterprises, more than one thousand tons of annual output in 2005 has 27, an increase of 6; has four annual output more than 5000t, while in 2004 only two; annual In 2000 - 5000t with 10 in 2004 to 8, there are more than 10 million yuan output value of 75, an increase of 7; annual output value exceeding 11 billion yuan, while in 2004 only eight, of which annual output value exceeding There are 6 200 million, an increase of 3. 122 manufacturing enterprises, 64 enterprises passed the ISO quality system certification, accounting for 52.5 percent, an increase of 5. There are 12 companies applied for various patents 74, an increase of 33, including raw materials, 20, UV formulations 44, the device 10.
Of radiation curing industry in recent years has yielded a rapid development, but with Europe, America, Japan and other developed countries, there is still a certain gap, mainly for small-scale enterprises, research and development capacity is weak, less high-end products, especially those with independent intellectual property products, branded products less; particularly affected by the international market oil prices impact, chemical raw material price increases resulting decline in economic efficiency of enterprises, seriously affect the research investment and expand production. Meanwhile, we should see that the radiation curing industry in line with China's economic and sustainable scientific development concept, the development of better prospects. Therefore, the industry must redouble our efforts to learn from each other and take the road of independent innovation, the radiation curing industry bigger and stronger, not only do radiation curing producing countries, but also to become a radiation-curable production of power.
