Discover our flagship range of high-performance silicon compounds, silane coupling agents, and specialty formulations engineered for global industrial requirements.
Ethyl silicate, chemically recognized as Tetraethyl Orthosilicate (TEOS) with the molecular formula Si(OC₂H₅)₄, serves as a crucial cornerstone within modern organosilicon chemistry. Its unique structure, featuring four hydrolyzable ethoxy groups attached to a central silicon atom, makes it the ideal agent for generating high-purity silica ($SiO₂$) networks. Upon controlled hydrolysis and subsequent polycondensation, it forms stable silanol bonds that crosslink with inorganic substrates, delivering unmatched thermal stability, chemical resilience, and structural reinforcement.
Globally, the industry is witnessing a structural shift. Historically localized to specialized metallurgy and basic binders, the demand for ethyl silicate silanes has surged across high-tech domains. These include semiconductor wafer processing, optical coating systems, refractory binders, and weather-resistant zinc-rich anti-corrosive coatings. Because it generates non-corrosive ethanol as a byproduct during curing rather than acidic derivatives, it is heavily favored in environments requiring sensitive substrates and clean processes.
By leveraging advanced synthesis routes, manufacturers like Shandong Boctok Chemical Co. can precisely control the degree of polymerization, providing both monomeric TEOS (typically referred to as Ethyl Silicate 28 based on its $SiO₂$ yield) and oligomeric variations like Ethyl Silicate 40. This flexibility allows global procurement departments to secure materials tailored precisely to their specific industrial viscosity, flash point, and hydrolysis speed requirements.
Bridging the gap between raw hydrocarbon resources and global technical consumption through advanced organosilicon manufacturing.
Shandong Boctok Chemical Co. was founded in 2012 as a marketing and sales center for Boctok™ domestic and overseas businesses and achieved sales of US$280 million in 2023. The BOCTOK brand specializes in serving the Russian market.
Boctok has three main product categories, the first core business of organosilicone covers twelve series of silane coupling agents and crosslinkers, including aminosilane, methacrylate silane, epoxy silane, vinyl silane, mercaptosilane, alkyl silane, ethyl silicate, chlorosilane, silane isocyanates, phenyl silane, ureidosilane and serosilane. Boctok also focuses on silicon oil, silicon resin, and silicon rubber, covering high-hydrogen silicone oil, dimethicone, vinyl silicone oil, polyphenylmethyldimethylsiloxane, phenyl silicone oil, silanol silicone oil and OH polymer, alkoxy silicone oil, methyl MQ resin, vinyl VMQ resin, room-temperature vulcanized methyl silicone rubber, 110 methyl vinyl silicone rubber, 120 methyl phenyl rubber. They are widely used in glass fiber, electronics, wind energy, daily necessities, chemical industry, coatings, adhesives, XLPE electric cables and hot water pipes, oil field drilling, textiles, rubber and molding, etc. to improve the quality and performance of the applied products.
Boctok's Tier II core business is petroleum resins. We have invested in a key hydrocarbon resin manufacturer in China. We currently have three operating hydrocarbon resin factories located in Zibo, Fushun, and Nanjing. Taking advantage of reliable and abundant raw materials from SINOPEC and PetroChina, our advanced production facilities, and our decades of marketing experience, our products are widely used by customers, including many Fortune 500 companies, in both domestic and overseas markets. These products include C9 hydrogenated resins, C5 hydrocarbon resins, C5 modified C9 hydrocarbon resins, C9 hydrocarbon resins, dicyclopentadiene, and methyl cyclopentadiene dimer.
Boctok also focuses on the agrochemical industry. It produces intermediates and raw materials for the production of pesticides, fungicides, insecticides, seed treatments, herbicides, plant growth regulators, and more. This diverse portfolio guarantees structural supply integration that mitigates volatility across raw materials and finished products.
Boctok's products are sold throughout China and exported to North America, Europe, Japan, South Korea, Australia, South America, the Middle East, India, Southeast Asia, Russia, etc., enjoying the well-deserved trust of customers worldwide who rely on consistent delivery and robust product verification.
Explore how our investments in safety automation and large-scale manufacturing structures guarantee supply consistency to the global market.
As global industries demand higher levels of product compliance, reliability, and traceabilty, Shandong Boctok Chemical Co. has undergone an extensive modernizing phase. We recently invested US$65 million to build a brand new manufacturing complex situated in the Shouguang Bohai Industrial Park, a certified, high-grade provincial chemical park in Shandong Province. This facility scales our capability significantly by adding 6 fully automated DCS (Distributed Control System) production lines, pushing our annual capacity of high-purity silane coupling agents to 30,000 metric tons.
These DCS configurations allow for live monitoring of physical reaction properties, minimizing product variance across batches. Alongside DCS, the integration of Safety Instrument Systems (SIS) ensures that critical production lines fail-safely in volatile environments, preserving both workforce and manufacturing assets. Every phase conforms tightly to ISO9001 quality management standards, meaning that from incoming petrochemical silane feedstocks to packaged export drums, our process is tightly controlled and documented.
Operating inside a high-standard chemical park demands top-tier ecological balance systems. We have constructed dedicated, eco-focused processing units, including advanced closed-loop waste gas collection systems and on-site chemical wastewater treatment systems. These actions ensure that our manufacturing process meets strict environment protection standards, removing supply interruption risks associated with localized regulatory clampdowns.
How global procurement officers can leverage China's advanced manufacturing footprint to maximize quality while reducing operational risks.
Our products undergo meticulous physical and chemical laboratory testing, utilizing chromatography and spectral instrumentation to confirm that chemical purities, hydrolysis indices, and flashpoints fall within specification limits. Every dispatch includes complete Certificates of Analysis (COA) to match global customs and internal factory inspection demands.
Our Shouguang industrial site provides scalable capabilities. We can adapt from single-ton specialized orders to bulk isotanks. This flexible capacity allows us to service international distributors, regional compounders, and massive multi-national industrial customers simultaneously.
Boctok relies on integrated road, rail, and sea logistics channels. Operating with immediate access to primary industrial seaports in Northern China, we coordinate swift customs processing and transport routes. This setup reduces transit times, ensuring that downstream manufacturing plants maintain minimal inventory buffers.
From structural sealants to agrochemical synthesis, our materials are adapted to perform under diverse and demanding industrial circumstances.
