Discover our core industrial silane portfolio. These functional organosilane compounds provide vital adhesion promotion, crosslinking, and surface modification capabilities across electronic, aerospace, and chemical formulations.
Founded in 2012, Shandong Boctok Chemical Co. has grown to become a dominant global force in high-purity organosilicon synthesis and hydrocarbon resin distribution. Operating as the primary marketing, technical support, and global sales center for Boctok™ domestic and overseas chemical supply lines, we realized an annual sales volume of US$280 million in 2023. Our dedicated BOCTOK brand focuses comprehensively on serving the Russian Federation, CIS nations, Eastern Europe, and global industrial markets with high-specification raw materials.
Our organosilicon supply portfolio spans twelve distinct series of silane coupling agents and crosslinkers. These include: aminosilanes, methacrylate silanes, epoxy silanes, vinyl silanes, mercaptosilanes, alkyl silanes, ethyl silicates, chlorosilanes, silane isocyanates, phenyl silanes, ureidosilanes, and specialized serosilanes. We complement our silane lines with premium silicone oils, high-hydrogen fluids, MQ resins, and room-temperature vulcanized (RTV) rubbers tailored for wire and cable, electronics, paint formulation, and mechanical castings.

Boctok has invested significantly in physical and chemical infrastructure to scale production while ensuring international safety and quality standards.
Industrial capabilities and commercial metrics driving our high-purity silane and resin divisions globally.
High-purity silanes act as essential molecular bridges, combining organic polymers with inorganic mineral fillers, glass substrates, and metal surfaces. In the modern global economy, these coupling agents are critical to accelerating structural performance, reducing environmental footprints, and ensuring system durability.
High-performance wind turbines rely on glass-fiber reinforced epoxy blades. Our aminosilanes and methacrylate silanes modify the surface of glass fibers, establishing covalent linkages with epoxy resins. This significantly increases tensile strength and prevents delamination under cyclical marine winds.
Our vinyl silane series provides moisture-curable crosslinking in Cross-linked Polyethylene (XLPE) power cables. This chemical framework permits power cables to maintain electrical and mechanical integrity at sustained temperatures exceeding 90°C, reducing dielectric losses.
With electronic devices shifting toward higher power densities and smaller microchips, epoxy silanes and vinyl silanes are used in Epoxy Molding Compounds (EMC). They couple silica fillers with the epoxy resin matrix, reducing thermal expansion differences and avoiding stress-induced micro-fractures.
Silanes such as epoxy, amino, and mercapto silanes function as wet-adhesion promoters in high-performance acrylic, polyurethane, and epoxy coatings. They prevent moisture migration to the substrate-polymer interface, protecting metallic structures against electrochemical corrosion.
Complementing our core organosilicon offerings, Boctok's Tier II business focus lies in advanced petroleum resins. We have invested in a leading hydrocarbon resin manufacturing group in China, operating three production hubs located in Zibo, Fushun, and Nanjing.
By leveraging reliable, direct-pipeline raw hydrocarbon streams from SINOPEC and PetroChina, our advanced polymerization units yield high-quality C5 hydrocarbon resins, C9 hydrocarbon resins, C5 modified C9 hybrid resins, C9 hydrogenated resins, and pure dicyclopentadiene (DCPD). These resins are critical formulation components for pressure-sensitive adhesives, hot-melt markings, and performance tires, used widely by global Fortune 500 companies.
Our dedicated Agrochemical Division produces high-purity chemical intermediates and active raw materials for the synthesis of crop protection solutions, including pesticides, fungicides, selective herbicides, plant growth regulators, and seed treatments.
Rigorous testing profiles across GC, MS, and FTIR instrumentation guarantee purity metrics exceed 99% for critical silane runs.
Equipped with high-volume DCS automation lines to handle bulk order demands, contract customization, and stable long-term supply.
Technical support specialists and field chemists assist with product compatibility and formulation optimization.
Direct supply routes and dangerous goods logistics networks ensure timely transport and port clearances globally.

Boctok chemicals and raw materials serve multiple downstream industries, including advanced polymers, protective coatings, electronics, and agricultural active formulations.
As downstream industries demand higher performance and more sustainable profiles, organosilicon development must evolve. Boctok Chemical's research and development roadmap focuses on three main areas:
Traditional monomeric alkoxy silanes release alcohols (VOCs) during hydrolysis. Our R&D team is scaling water-soluble, low-VOC silane oligomers that deliver equivalent coupling performance while keeping VOC levels well below international regulatory limits.
To support the high requirements of the semiconductor industry, we are expanding our metal-ion filtration systems. This target aims to supply electronic-grade amino, epoxy, and chlorosilanes with trace metal levels below 1 ppb, suitable for ultra-thin gate dielectric coatings.
We are optimizing raw materials sourcing and closed-loop chlorine recycling in chlorosilane synthesis. This chemical path reduces manufacturing waste, lowering the carbon footprint of our commercial silane lines.
Operating a chemical manufacturing and export business requires strict compliance with international safety and environmental frameworks. Boctok has recently invested US$65 million to construct a modern production complex within the Shouguang Bohai Industrial Chemical Park in Shandong Province. Spanning 6 automated DCS lines with an annual output capacity of 30,000 tons of silane coupling agents, this facility runs advanced safety instrumented systems (SIS) alongside full ISO9001 compliance.
To support global supply chains, we maintain registrations under relevant chemicals legislations, including REACH compliance for European distribution. Our logistics teams coordinate with international shipping lines and customs services to provide reliable delivery. In addition, our regional office network provides technical assistance, product recommendations, and custom logistics management for clients across the CIS and Eastern Europe.
Our organosilicon agents, silicone polymers, and petroleum resins are distributed across diverse industrial applications, supporting structural integrity and chemical performance.
