Oxidation causes yellowing epoxy systems as well as an important culprit ultraviolet light, the main source is sunlight, and therefore, especially in the face of produced products require customers to use outdoors, we would recommend the product to add a certain amount of UV-absorbing agent Boshan acrylic resin, can effectively absorb ultraviolet light, delaying yellowing. Furthermore, the resin used in conjunction with UV and antioxidant, can play a synergistic effect, play one plus one is greater than 2 results. 2013, the domestic industry with an unsaturated polyester resin production were concentrated in Jiangsu, Guangdong, Fujian, Shandong, Zhejiang, Hebei and other places. Jiangsu continues to lead the country, production reached 1.02 million tons; followed by Guangdong, production exceeded 300,000 tons; Fujian production exceeded 250,000 tons; small scale enterprises in Zhejiang Province, the EIA discontinued more production decline in recent years. 2013, unsaturated polyester resin foreign production in China reached 19 million tons, applications focused on high-end market. The largest domestic production Yabang paint companies still Zibo acrylic resin, the annual 240,000 tons, followed by days, Fukuda, Hua Xun, Ze source, FangXin etc., total output 650,000 tons breakthrough. From the industry as a whole with an unsaturated polyester resin technology trend analysis, Jiangsu and Shanghai is still the country's largest research and development, manufacturing OEM base. Jiangsu foreign SMC / BMC resin, resin wind power, desulfurization resin, shipbuilding resins, structural resins still leading the country, and promote the technological upgrading of the entire industry of Jiangsu. Jiangsu Province as the country's OEM base, the main export varieties of low-cost terephthalic resin and air dry DCPD resin, two OEM resin can reach more than 10 million tons. In recent years, national attention to environmental protection, vinyl ester resins growth accelerated, Jiangsu, Shanghai, and small enterprises reached more than 20, preliminary statistics, the national output of 4.3 million tons. It is worth noting that, in order to reduce costs north of acrylic resin, there have been a number of modified vinyl ester resin on the market, its poor corrosion resistance, short life cycle and cracking phenomenon has damaged the customers and markets.
