Qingdao Hengda Zhongcheng Technology Co., Ltd.
In 1965 Silane coupling agent KH‐550 is produced in Gaizhou factory
Silane coupling agent HENGDA-E8133(KH‐550, A‐1100) put into production in Gaixian Chemical Plant (the predecessor of HENGDA Chemical) in 1965.
• 1992-TECHNICALS EXPERTS BRING MASS PRODUCTION OF SILANE COUPLING AGENTS.
In 1992, under the background of reform and opening up, we undertook the original technical backbone, hired senior experts in the industry to re-form technical team of silane coupling agent, and established Gaizhou Hengda Chemicals Co., Ltd.
2000- EXPORT TO EUROPE
In July 2000, Hengda Chemical expanded its product range, realizing the mass production of new Methacrylate and Amino silanes including HENGDA-M2133 (equivalent to A-174), HENGDA-M8253 (equivalent to A-1120, A1122) ，HENGDA-M8252 (equivalent to A-2120) and many other silane coupling agents.
In July 2011, Hengda Chemical expanded its product range
In July 2011, Hengda Chemical expanded its product range, realizing the mass production of new Methacrylate and Amino silanes including HENGDA-M2133 (equivalent to A-174), HENGDA-M8253 (equivalent to A-1120, A1122) ，HENGDA-M8252 (equivalent to A-2120) and many other silane coupling agents.
Qingdao Hengda New Material Technology Co., Ltd was established.
In November 2017, Hengda Chemical planned to integrate the upstream and downstream of the industrial chain and invested USD 52 million to build Shandong Plant with annual capacity 30,000 tons. In December, Qingdao Hengda New Material Technology Co., Ltd was established.
planning: Phase II project of 100,000 tons coupling agents
This project will engage in cyclic utilization of the by-product hydrogen chloride to produce silane coupling agents, achieving environmental protection and a circular economy.
