1H,1H,2H,2H-Perfluorodecyltriethoxysilane is a fluoro-functional silane compound with the internal product code Siwin-F032. Assigned CAS registry number 101947-16-4, it serves as a raw material for release coating formulations and low surface energy surface modification processes. The product features a long perfluoroalkyl chain combined with triethoxysilyl groups, enabling both chemical bonding to inorganic substrates and low surface energy performance derived from fluorinated molecular segments.
This product is developed for commercial procurement and industrial formulation use, targeting manufacturers of release liners, functional coatings, and surface treatment materials. Its molecular structure provides consistent surface energy reduction across a range of applied systems, supporting stable performance in batch production.
As a fluoro silane coupling agent, 1H,1H,2H,2H-perfluorodecyltriethoxysilane acts as a surface modifier that forms covalent bonds with hydroxyl-containing substrates such as glass, silica, paper, and metal oxides. The ethoxy groups hydrolyze under appropriate moisture conditions to form silanol groups, which react with surface hydroxyl groups to create durable chemical attachment. The perfluorinated alkyl segment orients toward the air interface, delivering low surface energy, water repellency, and oil repellency to the treated surface.
The product is compatible with solvent-based, solvent-free, and emulsion-based formulation systems, supporting multiple industrial processing methods including dip coating, spray coating, and roll coating.

1H,1H,2H,2H-perfluorodecyltriethoxysilane is primarily used as a raw material for release coating formulations applied to paper, PET film, and BOPP film substrates. When incorporated into release layer formulations, it reduces the surface energy of the substrate surface, enabling clean release of pressure-sensitive adhesives, epoxy resins, and other viscous materials. This application serves the label manufacturing, protective film production, and composite material processing industries, where consistent release force control is required for production efficiency.
The product can be used as a standalone surface treatment component or blended with other silane and polymer additives to adjust release force levels and coating durability.
The fluorinated alkyl structure of the product provides both water and oil repellent properties when applied to inorganic surfaces. It is used for surface modification of glass, ceramic, and metal materials to reduce liquid adhesion and contamination retention. In architectural glass and optical component manufacturing, the silane treatment forms a thin, transparent modification layer that lowers surface wettability without affecting light transmittance.
For powder materials such as silica and talc, the product functions as a surface treatment agent to improve powder dispersion in fluoropolymer systems and reduce system viscosity during processing.
In industrial coating formulations, 1H,1H,2H,2H-perfluorodecyltriethoxysilane acts as an additive to enhance coating surface properties. It improves the anti-fouling performance of topcoats by reducing the adhesion of dirt, oil, and aqueous contaminants. It also supports anti-corrosion coating systems by improving the bonding between organic coating resins and metal substrates, reducing the risk of coating delamination under humid and corrosive environments.
The product is compatible with most solvent-based acrylic, epoxy, and polyurethane coating systems, and can be added directly during the formulation mixing process.
Siwin-F032 is available in multiple packaging specifications to accommodate different order volumes for industrial clients and commercial users:
25 L plastic drum: 25 kg net weight per drum, suitable for small-batch formulation testing and trial production
200 L iron drum with PTFE lining: 200 kg net weight per drum, standard for regular batch production
1000 L IBC container: 1000 kg net weight per container, designed for bulk commercial procurement and large-scale manufacturing
Custom packaging specifications can be arranged upon request to match specific production and logistics requirements.
The product should be stored in a cool, dry, and well-ventilated warehouse, with ambient temperature maintained between 5℃ and 30℃. Containers must remain tightly sealed when not in use to prevent moisture contact, which may cause hydrolysis of the ethoxy groups and affect product performance. Direct exposure to sunlight and heat sources should be avoided during storage and transportation.
Under proper storage conditions, the product has a shelf life of 12 months from the date of manufacture. Material safety data sheets are available upon request for handling, personal protection, and emergency response guidance.
The standard purity grade of Siwin-F032 is no less than 98% as measured by gas chromatography. Each batch is tested and accompanied by a certificate of analysis that reports actual purity values and key physical parameters for incoming quality verification.
This fluoro silane is compatible with substrates that contain surface hydroxyl groups, including paper, glass, silica, ceramic, and most oxidized metal surfaces. It can also be used to treat inorganic fillers and pigments to improve their compatibility with fluoropolymer and non-polar resin systems.
When stored in original sealed containers at 5℃ to 30℃ and protected from moisture and direct sunlight, the product maintains its specified performance for 12 months from the production date. Post-shelf-life material can be retested for key parameters to confirm suitability for use.
The product can be used in water-based systems when properly pre-hydrolyzed or formulated with appropriate emulsifiers. For water-based formulation development, technical support is available to recommend suitable hydrolysis conditions and addition procedures.
