Fumed Silica in adhesive application

Fumed Silica in adhesive applications in the adhesives and sealants, the fumed silica as a reinforcing agent and additives primarily played rheology control, anti-settlement, to prevent the flow of hanging and the reinforcing effect. Fumed silica of small particle size, surface area, surface Si-OH (Si-OH) and its aggregates more than three-dimensional branching structure, by making hydrogen bonds or van der Waals forces between the silica and polymer molecules, chlorine dioxide silicon molecules produce a strong effect, to reinforcement effect. Fumed Silica in adhesive and sealant systems uniformly dispersed, they can aggregate to form a silica network, aggregates through the surface of silicon-OH (Si-OH) and the polymer molecules to form hydrogen bonds, so that the flow system nature of restrictions, the viscosity increased, and thus play a role in thickening the same time, under the action of shear force, hydrogen bonding and silica networks were damaged, leading to decreased viscosity, which happened thixotropic effect, ease of construction, once the shear stress removed, silica network and the foryoga mation of hydrogen bonds again. So as to effectively prevent the product during storage and use of the settlement process in the flow of hanging. In the solvent-based PU adhesive for shoes to add a suitable fumed silica not only help improve the PU adhesive bond strength, but also can significantly extend the storage stability of the glue. (Reflected in viscosity and stability), the larger the current domestic shoe manufacturers have used PU glue, PU glue is generally used in models HL-150, HL-200, hydrophobic model: HB-215 to add the ratio is generally 0.5 ~ 1.5%. The national industry - the nation's largest fumed silica (fumed silica) factory in Guangzhou Ji Bi Sheng (GBS) Technology Co., Ltd. is now the largest production of fumed silica (white carbon black) enterprise. Produces fumed silica with hydrophilic and hydrophobic, hydrophilic product: HL-150, HL-200, HL-300, HL-380, hydrophobic products: HB-215, HB-220 (dimethyl-2 chlorosilane treatment) and (6-methyl Disilazane processing) HB620 and HB630, etc. more than 10 models products. It can be widely used (sealed lamp plastic, silicone rubber, electronic plastic, but also oxygen glue, anaerobic adhesive, polyurethane rubber, neoprene (all-purpose adhesive), and other adhesives; applied to silicone rubber, liquid silicone rubber, composite insulator, glass fiber reinforced composite yoga material / resin adhesive, clothing, silicone grease, silicone paste, cable filling paste, gel batteries, defoamers, paint, ink, rubber and other fields. Guangzhou Kyrgyzstan will Sheng Corporation (white carbon black) product quality is stable, can replace the imported (Germany Wacker, Degussa, Cabot United States, Japan and Germany Hill) and other company's products, product cheap, cheaper than imports the same product more than 30%. Ji Sheng company will provide our clients with high quality GC 2 silica products, perfect technology and thoughtful service, is willing to cooperate sincerely with you to achieve win-win situation.
