Tianshui Chenguang Fine Chemical CO.ltd, established in June, 2003, is a joint-stock chemical enterprise. With 10 million yuan registered capital, 3200 square meters’coverage area, 4 production lines and 55 million design investment, Chenguang has the production capability of 1500 tons of photoinitiators and pharmaceutical intermediat annually.Photoinitiators are mainly used in electronics,printing,ink,dope,painting and other similar industry. They can quickly cure by absorbing ultraviolet light and control the curing-time according to the different wave length of absorbed ultraviolet, which usually ranges from 200nm to 470nm. Because of no pollution, it is a vital developing stage of the environmental protection for chemical engineering , and it has wide applying range. For example, during the production line of mass automobiles, photoinitiators are added when spraying paint, that is to say, adding ultraviolet irradiator after the spray-paint stage,then they’ll completely solidify within 5 seconds without roasting. It has high adhesive and has bright reflect,which has been widely used all over the world.The apparent coatings on our common cell phones are all making use of photoinitiators in order to finalize in a short time.They are also used in other high adherence and high bright procedures.Under the support from civil policy and local government,Chenguang will fully implement the tactic of “strong industrial province” from Ganshu province, aim to innovation and deeply promote the strategy of "science and technology enterprises," "talent thriving enterprise", and "brand promoting enterprise". We will actively carry out scientific and technological research and development and projects,and strive to build our company as the Northwest&＃39;s largest chemical production base for photo-nitiators, pharmaceutical intermediates with first-class equipment and management.
