Company Introduction

HENGDA Chemical, headquartered in Gaizhou City, Liaoning Province. We are the first silane manufacturer in China since 1965.



In the early 1960s, the Institute of Chemistry of the Chinese Academy of Sciences supported the research of amino silane coupling agents for fiberglass composite project. The institute synthesized a -amino silane coupling agent in 1965 and named it KH-550 (equivalent to A-1100). KH-550 was put into production in GAIXIAN Chemical plant (the predecessor of HENGDA Chemical).



Due to the strong demand in the market and with the trust of customers, HENGDA invested USD 52 million build a new production plant which is located in Bohai Industrial Park, a provincial chemical industry park in Shouguang City, Shandong Province, to expand products range.
