High-purity alkoxysilane monomers and crosslinkers meticulously engineered to enhance adhesion, optimize surface characteristics, and crosslink polymer matrices.
Alkoxysilanes represent the core chemical interface that links inorganic surfaces (such as metals, glass, and mineral fillers) with organic matrices (including rubbers, engineering thermoplastics, and thermosets). As a premier global supplier of organosilicon solutions, Shandong Boctok Chemical Co. (founded in 2012) specializes in the production, distribution, and customization of diverse chemical classifications. Our sales peaked at US$280 million in 2023, reflecting our role in supporting key global supply chains.
Under our specialized brand, BOCTOK, we have developed target-market dominance in regions like Russia and the CIS, alongside high-growth markets in North America, Europe, East Asia, and the Middle East. Through advanced chemical processes, we convert basic silicones into specialized silane coupling agents and crosslinkers, encompassing twelve series of functional silanes, including aminosilane, methacrylate silane, epoxy silane, vinyl silane, mercaptosilane, alkyl silane, ethyl silicate, chlorosilane, silane isocyanates, phenyl silane, ureidosilane, and serosilane.
Understanding the hydrolysis profiles, volatile organic compound (VOC) emissions, and target applications of alkoxy crosslinkers.
The reactivity of alkoxysilanes relies heavily on the hydrolysis of their alkoxy groups (typically methoxy $-OCH_3$ or ethoxy $-OC_2H_5$) to silanol groups ($-SiOH$), which then undergo condensation to form siloxane linkages ($-Si-O-Si-$). Methoxy silanes undergo rapid hydrolysis, releasing methanol, which is highly suited for ambient temperature, fast-curing industrial coatings, adhesives, and sealants. Ethoxy silanes hydrolyze at a more moderate rate, releasing ethanol, making them highly desirable in applications where toxicity, odor, and VOC restrictions are paramount, such as in cosmetics, indoor construction sealants, and food-contact packaging.
Our state-of-the-art facilities in China produce high-purity silanes, ensuring low content of free chlorosilanes. This minimizes acidic sub-products and guarantees consistent, long-term formulation stability. By customizing the organic functional groups (e.g., vinyl, amino, epoxy, alkyl), we fine-tune the compatibilization between polymers and mineral substrates, resolving challenging interface adhesion tasks across structural composites.
Boctok serves as an integrated chemical platform spanning three major chemical categories to support multi-industry client networks.
Covering silane coupling agents, crosslinkers, silicone oils (dimethicone, high-hydrogen, vinyl, silanol, and alkoxy silicone oil), silicone resins (MQ and VMQ), and room-temperature vulcanized (RTV) or high-consistency rubbers. Essential for optimizing surface adhesion and enhancing polymer performance.
Sourced from high-grade raw monomers from SINOPEC and PetroChina. We produce C5 hydrocarbon resins, C9 hydrocarbon resins, C5/C9 copolymerized resins, and hydrogenated DCPD resins across three modern facilities in Zibo, Fushun, and Nanjing. Ideal for hot melt adhesives, rubber compounding, and road marking paints.
Manufacturing highly active pesticide intermediates, plant growth regulators, fungicides, insecticides, seed treatments, and herbicides. We emphasize eco-friendly formulations, matching advanced delivery systems to ensure effective crop protection and yield stability.
Global procurement centers require consistency, transparency, and regulatory compliance. Our recent US$65 million investment in the Bohai Industrial Park, Shouguang City, Shandong Province, establishes a new standard for advanced silane synthesis. Equipped with 6 fully automated Distributed Control System (DCS) production lines, our facility is engineered to run seamlessly, with an annual output of 30,000 tons.
Our automated facility utilizes high-precision fractional distillation columns and high-efficiency reactors to deliver structural silanes with narrow purity tolerances, enabling seamless integration into automated customer plants.
