Daken Chemical Limited  is a hi-tech company specialized in the area of R&D, production and sale of high end organosilicone productions. We have a group of scientific researchers with rich experience in this area. Daken concentrates on the exploit and manufacturing of kinds of new organosilicone monomers and intermediates. Our products cover organohalosilanes, organic amino silanes, organic hydrogen silanes, organoalkoxysilanes, chain-alkyl silanes, alkynylsilanes and fluoroalkyl silane, ect.

Exploit of organic silicon monomers：

There are a wide variety of organic silicon monomers on the market at present. Market application is available for more than 1800 kinds of moAnomers, which is increasing every year. As one of domestic leaders in the field of special type monomers development, by now, Daken Chemical  has developed more than 500 kinds of special monomers, including some custom=made items. We have around 300 monomers in stock, which mainly cover the application in all fields.
