SiSiB SILICONES is a leader of silicone gel manufacturers, and has been producing silane coupling agents since 1989. SiSiB is a leading manufacture of silanes and silicones, such as alkyl silanes, allyl silanes, silylating agent, etc. It started producing Silane Coupling Agent in 1989. Silane coupling agents are predominately used as mediators, binding organic materials to inorganic materials. The silane coupling agent will improve the electrical and mechanical strength properties of materials in wet or dry conditions. Organo silanes or organofunctional silanes are also a very important pharmaceutical and chemical industry, most notably as derivatizing and protecting reagents, intermediates in organic synthesis, reducing agents, surface modifiers, adhesion promoters, crosslinking agents. SiSiB silane siloxane concrete sealers also play an important role in silane siloxane chemistry industry. Silane Coupling Agent Mechanism Silane coupling agents are generally illustrated as X-Si-(OR)3. Silicone (Si) is the center of the silane molecule which contains an organic functional group (X) [ex: vinyl, amino, chloro, mercapto, epoxy silanes, etc.], with a second functional group (R) [ex: methoxy, ethoxy, etc.]. The functional group (R) will attach to an organic resin while the functional group (R) attaches to an inorganic material or substrate to achieve a "coupling" effect. Silane coupling agents are predominately used as mediators, binding organic materials to inorganic materials. As a result, silanes will improve the electrical and mechanical strength properties of materials in wet or dry conditions. The inorganic group (R) of the silane molecule will hydrolyze to produce silanol, which forms a metal hydroxide or siloxane bond with the inorganic material. The organic group (X) of the silane molecule will react with the organic material to produce a covalent bond. As a result, the organic material and the inorganic material are tightly bound together after heating. This unique property of silane coupling agents is utilized widely in the application of the silane coupling agents for the surface treatment of glass fiber products, performance improvement of fiber-reinforced plastics by the direct admixture to the synthetic resin, improvement of paints and other coating materials and adhesives, modification of surface properties of inorganic fillers, surface priming of various substrate materials, etc. How Silane Coupling Agent Is Used To Treat The Inorganic Fillers? Wet Method By mixing slurry of the inorganic materials in a dilute solution of the silane coupling agent, a highly uniform and precise surface treatment of the inorganic material can be obtained. Dry Method A high shear, high speed, mixer is used to disperse the silane coupling agent into the inorganic materials. The silane is generally applied either neat or as a concentrated solution. When compared to the Wet Method, the Dry Method is most often preferred for large-scale production, treating a large amount of filler in a relatively short time and generating relatively little mixed waste; however, it is more difficult to obtain uniform treatment with this method. Spray Method Spray the silane coupling agent on high temperature filler that was just taken out from furnace. The method may omit dry procedure and make the process simplify, but pay attention to perflation and ignite. You may have doubt that is silicone good for waterproofing?

Phenyl Functional Silicone, Phenyl Silicone Oil, Phenyl Modified Silicone, Diffusion Pump Fluid, silicone diffusion pump oil, Heat Transfer Fluid, Heat Transfer Oil Compared to the same viscosity of dimethyl silicone fluid, phenyl methyl silicone fluid has higher coefficient of viscosity-temperature, lower freezing point and higher flash point. The most commonly used high temperature silicone fluids are phenyl silicone fluids. When the phenyl group in the polysiloxane replaces the methyl group, oxidation resistance, thermal stability, and shear resistance are all improved. The phenyl group is usually introduced by a phenylmethylsiloxane or a diphenylsiloxane. phenyl methyl silicone oil with high phenyl content by SiSiB, a relaible silicone producer, is used as heat exchange fluid, dielectric coolants, base silicone diffusion pump oil for high temperature fluid and chromatographic stationary phases. The higher the phenyl content, the better the high temperature thermal stability. Refractive index also increases with phenyl concentrations. Silicone fluids with low phenyl content are used at lower temperatures and are usually used as lubricants for key equipment. SiSiB provides a wide range of phenyl silicone fluids with different viscosities. Low-viscosity phenyl fluids, SiSiB® PF8704 diffusion pump fluid, CAS No. 3982- 82-9, 1,1,5,5-Tetraphenyl-1,3,3,5-tetramethyltrisiloxane , , is designed for high vacuum pump; SiSiB® PF8705 diffusion pump fluids, CAS No.3390-61-2, 1,1,3,5,5- Pentaphenyl trimethyltrisiloxane, is designed for ultra-high and ultra-clean vacuum. SiSiB® PC19816 (Phenyl Trimethicone) has good compatibility which can improve the performance of a variety of cosmetic formulations. It is often used in cosmetics and beauty products functioning as an anti-foaming agent, hair conditioning agent and skin-conditioning agent. Phenyl Silicone Fluids Recommendations SiSiB® PC19816 SiSiB® PC19816 is a phenyl-modified polymethylphenylsiloxane which is co- soluble with ethanol and mineral oils. It is used in the formulations to improve the functions of cosmetic ingredients and used as a waterproof additive to reduce the viscosity of the formulation so that many effects can be achieved. INCI Name: Phenyl methicone. SiSiB® PC19826 SiSiB® PC19826 is a phenyl-modified polymethylphenylsiloxane which is co- soluble with ethanol and mineral oils. It is used in the formulations to improve the functions of cosmetic ingredients and used as a waterproof additive to reduce the viscosity of the formulation so that many effects can be achieved. INCI Name: Phenyl Trimethicone. SiSiB® PF8250 SiSiB® PF8250 is polyphenylmethyldimethylsiloxane, which is similar to Dow's DC-510, Shin-Etsu's KF-50. It has low viscosity, low freezing point, heat resistance, relatively high flash point, expansion coefficient, superior electrical performance (anti-corona, the average high pressure). SiSiB® PF8255 SiSiB® PF8255 is polyphenylmethyldimethylsiloxane, which is similar to Dow's DC-550, Shin-Etsu's KF-54. It has a good miscibility with other organic resins, suitable for skin protection and soften, and is used for high-temperature heat carrier or as insulation oil, high-temperature heating oil bath and base oil. SiSiB® PF8704 Silicone Diffusion Pump Fluid SiSiB® PF8704 is a single component fluid designed for high vacuum applications, which is equal to Dow's DC-704, Shin- Etsu's HIVACF-4. Its low vapor pressure and thermal stability make it popular in processes such as vacuum coating, metallurgical work.
