Direct supply of high-purity silane coupling agents, organosilicon monomers, and specialized biochemical agents optimized for heavy industrial applications.
Shandong Boctok Chemical Co. was founded in 2012 as a centralized global marketing and sales operation for Boctok™ domestic and overseas business units. Empowered by decades of combined technological research, the company achieved an outstanding annual sales volume of US$280 million in 2023. Representing our core footprint, the BOCTOK brand specializes in delivering superior performance chemical solutions to the Russian market while meeting the stringent demands of European and international enterprises.
Boctok operates across three high-impact manufacturing divisions. Our tier-one core business covers 12 diverse series of silane coupling agents and crosslinkers. These formulations encompass aminosilane, methacrylate silane, epoxy silane, vinyl silane, mercaptosilane, alkyl silane, ethyl silicate, chlorosilane, silane isocyanates, phenyl silane, ureidosilane, and serosilane. Furthermore, we specialize in 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 methyl silicone rubber, 110 methyl vinyl silicone rubber, and 120 methyl phenyl rubber.
Alkyl silanes represent a cornerstone of advanced surface modification and structural protection chemistry. Synthesized by linking non-polar hydrocarbon chains to hydrolyzable alkoxy groups, these compounds possess a unique dual functionality: the silicon-functional alkoxy groups (such as methoxy or ethoxy) bond covalently to inorganic substrates, while the organic alkyl chain (ranging from methyl up to octyl groups) extends outward to create a low-surface-energy barrier.
This hydrophobic network prevents liquid water infiltration while allowing vapor transmission (breathability). In building preservation, alkyl silanes protect concrete structures from freeze-thaw degradation, efflorescence, and chloride-ion penetration. In polymeric compounding, they act as critical surface treatments for mineral fillers like silica, kaolin, and aluminum trihydroxide (ATH), enhancing filler dispersion, reducing viscosity, and boosting the overall physical and mechanical integrity of the composite system.
Procurement directors in aerospace, automotive, electronics, and heavy civil construction face escalating demands for materials that comply with strict regulatory frameworks without sacrificing performance. Key challenges include maintaining consistent alkyl silane purity, securing long-term pricing agreements, and ensuring stable cross-border supply chains. Under high-humidity and high-shear environments, even minor variations in silane purity can lead to coating failures, compromised structural durability, or delamination in microelectronics packaging.
As regulatory frameworks shift to restrict volatile organic compounds (VOCs), the global market is transitioning toward water-borne silane emulsions and high-purity monomeric silanes. Manufacturers must provide detailed EHS documentation, REACH compliance certifications, and reliable batch-to-batch tracking data to meet the demands of international supply chains.
Shandong Boctok Chemical leverages two key corporate business units to deliver integrated chemical solutions:
The next generation of organosilicon technology is focused on environmental compatibility and high-temperature performance. Boctok's research and development roadmap focuses on three main areas:
Developing oligomeric alkyl silanes that minimize ethanol/methanol emissions during hydrolysis, satisfying the strictest international building air quality requirements.
Merging the heat and UV resistance of MQ resins with the mechanical properties of epoxies to create high-durability coatings for marine environments.
Synthesizing targeted organosilicon polymers to act as controlled-release agents, improving the efficiency of active pesticide ingredients.
High-capacity automated systems built to meet global industrial standards and minimize environmental impact.
We recently invested US$65 million to establish a modern manufacturing facility in the Bohai Industrial Park, Shouguang City, Shandong Province. This project adds 6 fully automated DCS production lines with an annual capacity of 30,000 tons of silane coupling agents.
Our production lines are equipped with automated Distributed Control Systems (DCS) and Safety Instrumented Systems (SIS) to ensure process safety, consistent quality, and strict alignment with ISO9001 standards.
We minimize industrial emissions by routing production waste streams through dedicated gas collection scrubbing systems and multi-stage wastewater treatment units, ensuring compliance with environmental regulations.
Every product batch undergoes testing in our central laboratory to confirm compliance with global purity and reactivity standards before dispatch.
Our automated production facilities enable us to scale production runs efficiently and meet high-volume global demands.
Our dedicated technical and commercial support team is available online to address specifications, logistics, and integration questions.
Strategic warehousing, partnerships with global logistics hubs, and direct links to coastal ports ensure prompt order dispatch and delivery.
Our materials portfolio is divided into two primary structural chemical classifications to simplify international procurement:
Comprehensive organosilicone series, specialized resins, rubber precursors, and structural additives.
Raw materials, catalysts, and formulation intermediates for global agricultural applications.
Our products serve as critical process aids and protective additives in various global manufacturing fields.
Supporting critical manufacturing steps, surface treatments, and advanced materials engineering globally.
Answers to common questions regarding organosilicon specifications, industrial applications, and procurement logistics.
Alkyl silanes contain hydrolyzable alkoxy groups that react with surface moisture or hydroxyl groups on inorganic substrates (such as concrete, stone, or silica) to form silanol intermediates. These intermediates then condense to form durable siloxane bonds (Si-O-Si). The non-polar alkyl group extends outward, lowering the substrate's surface energy to provide hydrophobic properties without sealing the pores or restricting vapor transmission.
Our Shouguang facility features fully automated Distributed Control Systems (DCS) and Safety Instrumented Systems (SIS). These systems monitor temperature, pressure, feed rates, and reaction times in real time to maintain process consistency. Each batch undergoes quality control testing (such as gas chromatography and refractive index measurements) in our lab before packaging.
Vinyl silanes, such as Vinyltrimethoxysilane (VTMO) and Vinyltriethoxysilane (VTEO), are widely used in the production of crosslinked polyethylene (XLPE) for power cables and hot water pipes. These silanes are grafted onto the polyethylene backbone, allowing moisture-induced crosslinking that enhances the polymer's thermal stability, mechanical properties, and environmental stress crack resistance (ESCR).
Reactive silanes are sensitive to moisture and must be stored in dry, tightly sealed containers under a nitrogen blanket. When exposed to atmospheric moisture, they undergo hydrolysis, releasing alcohols (methanol or ethanol) and forming oligomers. Most of our high-purity silanes have a shelf life of 12 to 24 months from the manufacturing date when stored in their original unopened packaging below 25°C.
Specialized silanes, advanced silicones, and high-performance MQ resins designed for challenging industrial and chemical processes.
