my country’s silane coupling agent production maintains steady growth and the industry’s technical barriers are high

Silane coupling agent, also known as silane treatment agent and silane primer, is a special structural low-molecular organic silicon compound with both hydrophobic and hydrophilic functional groups. It can be used as a chemical agent for glass fiber reinforced plastics. Silane coupling agents have unique physical and chemical properties and are widely used in products such as tackifiers, sealants, and surface treatment agents. According to different constituent materials, silane coupling agents can be divided into three types: epoxy silane coupling agents, sulfur-containing silane coupling agents and amino silane coupling agents.

The silane coupling agent industry has high technical barriers. The purity and quality of intermediates can directly affect its performance, but it is difficult to control during the production process. At present, the main synthesis methods of silane coupling agents in the world include dehydrohalogenation reaction method, direct synthesis method, Grignard reagent method, alcoholysis method, hydrogen silicon addition method, etc. The direct synthesis method is the mainstream preparation method of silane coupling agents. It refers to the direct reaction of halogenated hydrocarbons and silicon powder under heating conditions using copper powder as a catalyst to obtain the finished product; the Grignard reagent method uses silane and Grignard reagent as raw materials. Then add organic solvent to prepare the silane coupling agent. This method is mostly used in laboratories and is not suitable for large-scale production.

According to the “2022-2027 China Silane Coupling Agent Industry Market Supply and Demand Status and Development Trend Forecast Report released by the Industrial Research Center , In recent years, functional silanes have become an important industrial raw material, and the industry’s prosperity has continued to increase. my country is the world’s largest producer of functional silanes, accounting for nearly 60% of the world’s production capacity. Silane coupling agents are the mainstream functional silane products, accounting for 80.0% of the market. Driven by market demand, my country’s silane coupling agent production continues to grow. In 2021, my country’s silane coupling agent output reached 216,000 tons, a year-on-year increase of 16.7%.

Silane coupling agents can improve the actual bonding strength of polymers and inorganic substances and are mainly used in textile chemicals, glass fiber composite materials, rubber products, wires and cables, sealants and other fields. With the rapid development of the construction industry, the output of fiberglass composite materials in my country continues to grow. In 2021, my country’s glass fiber composite material output reached 5.812 million tons, a year-on-year increase of 13.7%. With the rapid development of downstream industries, the market space for silane coupling agents continues to expand.

There are many silane coupling agent manufacturers in my country, and the market competition is fierce. Nanjing Yudeheng Fine Chemicals, Jiangsu Chenguang Coupling Agents, Dongguan Hongbai Chemicals, etc. are the leading silane coupling agent companies in my country. Driven by the technological innovation of local enterprises, my country’s silane coupling agent industry has begun to develop in a high-quality direction.

Industry analysts said that as a representative product of functional silanes, silane coupling agents have been widely used in many fields due to their unique properties. my country is a major producer of silane coupling agents, and its output has maintained a steady growth trend for a long time. However, at present, the silane coupling agent industry has high technical barriers, and local companies urgently need to increase investment in research and development to drive the localization rate of high-end products to continue to increase.
