In the field of high-performance organosilicon chemistry, Methyltrimethoxysilane (MTMS, CAS No. 1185-55-3) stands out as a foundational crosslinking agent, coupling agent, and surface modifier. Known for its trifunctional alkoxysilane structure, MTMS enables the creation of highly hydrophobic, heat-resistant, and chemically stable matrices. By bridging the gap between inorganic materials (such as glass, metals, and minerals) and organic polymers, it is widely used in coatings, sealants, electronics, and composites.
As a global leader in high-performance chemicals, Shandong Boctok Chemical Co. was established in 2012. Our sales reached US$280 million in 2023, reflecting our commitment to advanced manufacturing standards, stable supply chains, and customer service. The BOCTOK brand is highly recognized worldwide, with a strong focus on serving the Russian market alongside other major global regions.
Our organosilicon portfolio covers twelve distinct series of silane coupling agents and crosslinkers. These include: aminosilane, methacrylate silane, epoxy silane, vinyl silane, mercaptosilane, alkyl silane, ethyl silicate, chlorosilane, silane isocyanates, phenyl silane, ureidosilane, and serosilane.
Additionally, Boctok focuses on high-quality silicone derivatives such as high-hydrogen silicone oil, dimethicone, vinyl silicone oil, polyphenylmethyldimethylsiloxane, phenyl silicone oil, silanol silicone oil, OH polymer, alkoxy silicone oil, methyl MQ resin, vinyl VMQ resin, room-temperature vulcanized (RTV) methyl silicone rubber, 110 methyl vinyl silicone rubber, and 120 methyl phenyl rubber.
In addition to our silicone range, Boctok has invested in a key hydrocarbon resin manufacturer in China. We currently operate three dedicated production plants in Zibo, Fushun, and Nanjing. Utilizing reliable and abundant hydrocarbon feedstocks from major state-owned enterprises SINOPEC and PetroChina, our production lines deliver high-performance C9 hydrogenated resins, C5 hydrocarbon resins, C5 modified C9 hydrocarbon resins, C9 hydrocarbon resins, dicyclopentadiene (DCPD), and methyl cyclopentadiene dimer.
These advanced petroleum resins are widely utilized by Fortune 500 enterprises for structural adhesives, road markings, coatings, and rubber compounds. Furthermore, Boctok is active in the agrochemical industry, manufacturing intermediates and active ingredients for insecticides, fungicides, seed treatments, herbicides, and plant growth regulators.
Methyltrimethoxysilane is a key organosilane with the chemical formula CH₃Si(OCH₃)₃. Synthesized through the esterification of methyltrichlorosilane with methanol, the reaction yields three methoxy leaving groups attached to a silicon atom with an active methyl group. This molecular structure gives it a dual nature: the hydrolyzable methoxy groups react with water to form silanols, while the non-hydrolyzable methyl group provides hydrophobic properties and thermal stability.
Upon hydrolysis, MTMS releases methanol as a byproduct and forms highly reactive methylsilanetriol intermediates. Under acidic or basic conditions, these intermediates undergo condensation to form siloxane (Si-O-Si) linkages. This process creates a three-dimensional silicone network that binds tightly to polar surfaces and inorganic substrates:
Boctok Chemical
1. Hydrolysis: CH₃Si(OCH₃)₃ + 3H₂O ==> CH₃Si(OH)₃ + 3CH₃OH
2. Condensation (Self): n[CH₃Si(OH)₃] ==> [CH₃SiO₁.₅]n + 1.5nH₂O (Polymethylsilsesquioxane Network)
3. Condensation (Substrate): CH₃Si(OH)₃ + Substrate-OH ==> Substrate-O-Si(OH)₂CH₃ + H₂O
This hydrolysis-condensation reaction is crucial for industrial applications. It makes MTMS an excellent choice for water-repellent treatments, anti-corrosive coatings, structural glass sealants, and moisture-cure crosslinkers in room-temperature vulcanizing (RTV) silicone rubbers. Modern synthesis focus is on reducing free methanol content, improving stability, and ensuring clean reaction pathways.
Our commitment to sustainable production, advanced automation, and consistent product quality.
Boctok recently invested US$65 million to construct a new manufacturing facility in Bohai Industrial Park, Shouguang City, Shandong Province. This investment expands our silane coupling agent production capabilities, ensuring stable supply chains and competitive lead times.
The facility features 6 fully automated production lines managed by a Distributed Control System (DCS) and a Safety Instrumented System (SIS). These systems monitor critical reaction parameters, such as feed rates, temperatures, and pressures, to maintain consistent product quality and safe operations.
With a yearly capacity of 30,000 metric tons of silane coupling agents, our operations are optimized to handle high-volume demands. The plant is certified to ISO9001 quality management standards to ensure compliance with strict procurement criteria.
