Siwin-9221
Dimethyldimethoxysilane
Description:
As an organosilicon compound, dimethyldimethoxysilane possesses both Si-C and Si-O bonds. The presence of these bonds endows it with good chemical stability and reactivity. Under certain conditions, it can undergo hydrolysis reactions, reacting with acids, bases, or other compounds containing active hydrogen to form the corresponding silanols or silicates. In addition, dimethyldimethoxysilane can also be used as a silane coupling agent, reacting with inorganic fillers (such as silica, aluminum hydroxide, etc.) and organic substrates (such as plastics, rubbers, etc.) to enhance the interfacial adhesion and durability between them..

Application
Silicone resin modifier:Dimethyldimethoxysilane can be used as a modifier for silicone resins to improve the performance and processing characteristics of the resin.
Silicone vulcanizate structure control agent and chain extender: In silicone vulcanizates, Dimethyldimethoxysilane acts as a structure control agent and chain extender, which can improve the machining properties, prolong the storage time of the vulcanizate, and can replace hydroxyl silicone oil.
Filler treatment agent: Dimethyldimethoxysilane is widely used in the treatment of silicone rubber and white carbon black. As a filler treatment agent, it enhances the overall performance of the material.
Synthesis of various macroporous silica aerogels: Dimethyldimethoxysilane can be used to synthesize various macroporous silica aerogels, and dielectric silicone rubbers with high dielectric constants can also be prepared through Dimethyldimethoxysilane.
Preparation of phthalocyanine-loaded hollow silica nanoparticles: In the preparation of phthalocyanine-loaded hollow silica nanoparticles, Dimethyldimethoxysilane is used for near-infrared photodynamic and photothermal synergistic therapy.
