Explore our highly requested commercial silanes optimized for coating crosslinking, glass fiber treatment, and adhesion promotion.
Shandong Boctok Chemical Co. was founded in 2012 as a centralized global marketing and sales center for Boctok™ domestic and overseas chemical operations. Over more than a decade of robust expansion, our chemical solutions have served high-end industries globally, reaching a milestone consolidated sales revenue of US$280 million in 2023. Our brand represents structural excellence, highly competitive logistics networks, and tailored localization, focusing on developing the industrial raw materials market with custom configurations.
How our organofunctional silanes solve fundamental adhesion, durability, and corrosion challenges across diverse substrates.
Silane coupling agents act as chemical bridges between organic polymer matrices (such as acrylics, epoxies, polyurethanes, and polyesters) and inorganic substrates (glass, metals, silica, and mineral fillers). The hydrolyzable alkoxy groups react with moisture to form silanols, which condense with metal hydroxides on the substrate surface. Meanwhile, the organofunctional group copolymerizes with the resin, establishing covalent chemical bonds that withstand mechanical stress, thermal expansion, and moisture ingress.
By incorporating silane crosslinkers like Tetraethoxysilane (TEOS) or specialized trialkoxysilanes into liquid coating systems, formulators can design ambient-cure or moisture-cure mechanisms. This crosslinking process significantly increases crosslink density, improving hardness, chemical resistance, anti-graffiti properties, thermal stability, and scrub resistance. It transforms simple thermoplastic coatings into high-performance thermosetting networks.
Three main structural product lines engineered to serve modern global industries.
Covers 12 functional series of silane coupling agents and crosslinkers, including aminosilanes, methacrylate silanes, epoxy silanes, vinyl silanes, mercaptosilanes, alkyl silanes, ethyl silicates, chlorosilanes, silane isocyanates, phenyl silanes, ureidosilanes, and serosilanes. Further includes premium dimethicone, vinyl silicone oils, MQ/VMQ resins, and room-temperature vulcanized rubbers.
Tailored synthesis of raw materials and active pharmaceutical/agrochemical intermediates. We supply the active ingredients necessary for producing high-stability pesticides, fungicides, seed treatments, systemic herbicides, and organic plant growth regulators used globally.
Sourced via reliable, premium raw material streams from SINOPEC and PetroChina. We operate three specialized hydrocarbon resin manufacturing hubs in Zibo, Fushun, and Nanjing, offering high-purity C5 and C9 petroleum resins, hydrogenated resins, and DCPD derivatives for adhesives and paints.
The demand for organosilicones in the industrial coating market is growing rapidly due to stricter environmental laws on volatile organic compound (VOC) emissions. Modern architectural and industrial coatings are transitioning towards waterborne, high-solid, and UV-curable formulations. Under these conditions, silane additives are essential to maintain performance.
Our recently established manufacturing facility in the Bohai Industrial Park, Shouguang City, Shandong Province (representing a strategic investment of US$65 million) extends our silane production chain. Featuring 6 automated DCS lines, the site yields an additional 30,000 tons of silane coupling agents annually. This capacity allows Shandong Boctok Chemical Co. to provide stable global supply, minimizing the logistics bottlenecks currently affecting the chemical sector.

Answers to common formulation questions from our technical support team.
A: For additive applications, we generally recommend starting with 0.5% to 1.5% silane by weight, calculated based on the total resin solids or the dry weight of pigment/fillers. If used for surface pre-treatment, prepare a diluted 0.1% to 1.0% aqueous alcoholic solution.
A: N-β-(Aminoethyl)-γ-aminopropyltrimethoxysilane (CAS 1760-24-3) features a diamino structure containing one primary and one secondary amine group. This design provides higher reactivity and thermal stability, making it ideal for phenolic, epoxy, melamine, and polyurethane thermoset coatings.
A: Organofunctional silanes are sensitive to atmospheric moisture. We package our silanes under dry nitrogen gas in air-tight drums. Keep containers tightly sealed and store them in a cool, dry, and well-ventilated warehouse.
A: Yes. Our R&D team works with paint and coatings manufacturers to produce custom silane oligomers. These oligomers offer lower VOC emissions, reduced flash points, and enhanced storage stability compared to monomeric silanes.
