CAS No. 4420-74-0 Mercaptopropyltrimethoxysilane, Silane Coupling Agents

HENGDA-M4133

Chemical name: 3-Mercaptopropyltrimethoxysilane

1. It is widely used in natural and synthetic rubber, as a reinforcing agent and crosslinking accelerator., suitable for NR, EPDM, SBR, polysulfide rubber, styrene-butadiene rubber, nitrile rubber, neoprene and polyurethane rubber, etc.
2. It can be used in composite materials (eg. resin glass fiber composites), coatings, inks glues and sealing materials, etc.
3. It is often used to treat inorganic fillers such as glass fiber, SiO2, quartz, talc, mica, act as an activator, coupling agent, crosslinking agent, and reinforcing agent in polymers such as rubber and silicone rubber.
4. The mercapto functional group gives it special effects as an antirust agent on metal surfaces, used to treat the surface of gold, silver, copper and other metals to improve their corrosion resistance, oxidation resistance and improve its bonding performance to polymer materials.

Hengda Chemical, headquartered in Gaizhou City, Liaoning, is 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 aminosilane coupling agents for the composite material project. The institute synthesized a γ -aminosilane coupling agent in 1965 and named it KH-550 (corresponding to A-1100). KH-550 was put into production in the chemical plant in Gaizhou County (the predecessor of HENGDA Chemical).

Hengda Chemical recently invested RMB350 million yuan to build a production base in Shandong. The new factory is located in Bohai Industrial Park-a provincial chemical industry park in Shouguang City, Shandong, to expand the product chain of organosilane coupling agents. It has built 6 DCS automatic production lines with an annual output of 30, 000 tons of silane coupling agent.

The production lines in the new factory are equipped with DCS automatic remote-control operating system, SIS safety instrument system and other safety facilities, the ISO9001 quality management system standards are implemented throughout the process to ensure stable quality. Environmental protection treatment facilities such as waste gas collection and treatment system and sewage treatment system have been built.

Qingdao Hengda New Material Technology Co., Ltd. Was established in 2017 as a marketing center for Hengda Chemical to carry out domestic and foreign businesses, achieving sales of RMB800 million yuan (120 million US dollars) in 2022.

Hengda Chemical mainly specializes in producing HENGDA-E8133(KH-550/A-1100)and amino and bisamino silane coupling agents, covering Amino silane and Methacrylate silane, Epoxy silane, Vinyl silane, Mercapto silane, Alkyl silane, Ethyl Silicate, Chlorine silane, Isocyanate silane, Phenyl silane, Ureido silane and Sulfur silane, There are twelve series silane coupling agents and Cross-Linking Agent. They are widely used in glass fiber, electronics, wind power, daily necessities, chemical industry, coatings, adhesives, oilfield drilling, textiles, rubber and casting, etc. To improve the quality and performance of applied products.

The products are sold all over the China, and exported to North America, Europe, Japan, South Korea, Australia, South America, the Middle East, India, Southeast Asia, Russia, etc., well received by users.

Relying on advanced production equipment, complete testing methods and quality management system (ISO9001), Hengda Company provides customers with high-quality products and services and establishes long-term friendly cooperative relations with customers at home and abroad, taking the customers′ needs as a matter of primary importance.
