Traditional surface coatings block concrete pores physically. However, these barriers degrade under ultraviolet exposure, freeze-thaw cycles, and continuous mechanical stress. Modern civil engineering relies on penetrative organofunctional silanes to alter the substrate's surface energy chemically.
By coating capillaries with a microscopic, chemically bonded hydrophobic film, silanes prevent liquid water ingress while preserving concrete's vapor permeability. This balance allows internal moisture to evaporate, preventing localized blistering, structural spalling, and sub-surface steel rebar corrosion.
With more than a decade of research, Shandong Boctok Chemical Co. has developed next-generation organosilicone formulations designed to extend the lifespan of municipal infrastructure, high-rise building envelopes, and marine engineering structures.
Modern engineering projects require durable, high-performance waterproofing systems. Our silane materials are engineered to meet global standards and custom specifications.
As governments prioritize infrastructure maintenance over new construction, silanes play a vital role in protecting bridges, highways, and tunnels from water damage and deicing salts.
Global procurement teams prioritize solvent-free, water-based silane emulsions to comply with strict regional VOC limitations and green building certifications, including LEED and BREEAM.
From reactive monomeric silanes like trialkoxysilanes to polymeric siloxanes, we deliver precise active content percentages (up to 99% purity) for specialized concrete conditions.
Established in 2012, Shandong Boctok Chemical Co. functions as the core sales, marketing, and distribution center for Boctok™ domestic and global operations. Under our specialized BOCTOK brand, we serve Russia and global industrial markets with high-performance silicones, petroleum resins, and agricultural chemicals.
Our organosilicone portfolio includes twelve series of silane coupling agents and crosslinkers: aminosilane, methacrylate silane, epoxy silane, vinyl silane, mercaptosilane, alkyl silane, ethyl silicate, chlorosilane, silane isocyanates, phenyl silane, ureidosilane, and serosilane.
We also specialize in high-hydrogen silicone oil, dimethicone, vinyl silicone oil, polyphenylmethyldimethylsiloxane, phenyl silicone oil, silanol silicone oil, and OH polymer. In addition, our resin and rubber solutions cover alkoxy silicone oil, methyl MQ resin, vinyl VMQ resin, and room-temperature vulcanized methyl silicone rubber.
Our Tier II business specializes in high-quality petroleum resins, produced in partnership with key manufacturers in Zibo, Fushun, and Nanjing. Utilizing raw materials from SINOPEC and PetroChina, we produce C9 hydrogenated resins, C5 hydrocarbon resins, C5 modified C9 resins, dicyclopentadiene (DCPD), and methyl cyclopentadiene dimer.
These advanced polymers are widely used in adhesives, hot-melt road marking paints, coatings, and rubber formulations by global partners, including Fortune 500 companies.
We supply intermediates and active raw materials for the production of crop protection products, including pesticides, fungicides, insecticides, seed treatments, herbicides, and plant growth regulators.
By integrating silicone surfactant technology with active intermediates, we improve product spreading, rainfastness, and delivery efficiency in agricultural applications.
High-purity silanes, crosslinkers, and specialized functional fluids for modern compounding industries.
Targeted intermediates and adjuvant materials designed for crop protection formulations.
Silanes operate through a two-step chemical process: hydrolysis and condensation. When applied to concrete, masonry, or brick, the alkoxy groups of the silane react with ambient moisture in the substrate to form reactive silanol intermediates ($Si-OH$), releasing alcohols as byproducts.
These silanols then react with hydroxyl groups ($OH$ groups) on the surface of silicious building substrates. Through a condensation reaction, they form stable siloxane bonds ($Si-O-Si$), chemically bonding the active hydrophobic compound to the substrate's mineral matrix.
This molecular network repels liquid water while allowing water vapor to pass through. By keeping water out and letting vapor escape, the treatment protects against structural damage from freeze-thaw cycles and chemical degradation.
Boctok recently invested US$65 million to build a modern production plant in the Bohai Industrial Park, a provincial-level chemical industry zone in Shouguang City, Shandong Province. This facility expands our production chain of silane coupling agents with six automated DCS production lines, achieving an annual capacity of 30,000 tons.
Our production lines are equipped with Distributed Control Systems (DCS) and Safety Instrumented Systems (SIS). These remote control technologies maintain precise temperature and pressure profiles to ensure batch-to-batch product consistency.
We apply ISO9001 standards throughout the manufacturing process. From raw material intake to final packaging, every step is documented and verified to meet international quality baselines.
The facility features integrated waste gas collection and treatment infrastructure alongside a dedicated wastewater processing loop. These systems thermal-oxidize VOC emissions and neutralize discharge liquids to minimize environmental impact.
Boctok chemicals are sold throughout China and exported to North America, Europe, Japan, South Korea, Australia, South America, the Middle East, India, Southeast Asia, and Russia. We have established regional logistics and distribution networks to ensure timely delivery.
We support regulatory compliance across export destinations, including EU REACH preregistrations, Russian GOST standards, and material safety documentation. Our logistical partners handle bulk delivery requirements, including ISO tanks and heavy-duty drums, to ensure safe transport.
Whether you require bulk silanes for road marking paint, specialized agricultural adjuvants, or silane coupling agents for cross-linked polyethylene (XLPE) power cabling, Boctok provides consistent chemical quality and technical support.
