Applications of 5089-70-3
| Industry | Application | Process |
|---|---|---|
| Rubber Industry | Acts as a coupling agent between silica (white carbon black) and the rubber matrix to enhance mechanical properties and abrasion resistance of vulcanized rubber | Mixed with silica, natural rubber, or synthetic rubbers (e.g., SSBR, BR) during rubber compounding; interfacial covalent bonding is achieved via high-temperature vulcanization |
| Coatings & Inks | Functions as a performance additive to improve adhesion and water resistance of organic coatings on inorganic substrates (e.g., glass, metals, ceramics) | Incorporated as an additive into coating formulations; undergoes hydrolysis and condensation during film formation to establish Si–O–M covalent bonds (M = metal/glass substrate) |
| Composites | Enhances interfacial bonding between reinforcing fibers (e.g., glass fiber, carbon fiber) and organic resin matrices (e.g., epoxy, unsaturated polyester) | Applied via fiber surface pre-treatment: fibers are immersed in a dilute aqueous ethanol solution containing the silane, followed by hydrolysis and drying prior to resin impregnation and curing |
| Adhesives | Improves adhesive strength and resistance to hot/wet conditions for both inorganic fillers (e.g., calcium carbonate, talc) and bonded substrates | Added directly as a formulation component into adhesive systems (e.g., epoxy adhesives, acrylic adhesives); participates in crosslinking and bridges organic–inorganic phases during cure |
