Anwendungen
BeschreibungTrimethoxy (methyl) silane is an organosilicon compound. It can be used as a crosslinker in the preparation of polysiloxane polymers. It can also be used as an acid scavenge used in the formation of substituted azulenes from allenylsilanes and tropylium tetrafluoroborate. It can also be used as the precursor for synthesis of flexible silica aerogels.
VerwendenMethyltrimethoxysilane(MTMS) in combination with iron nitrate altered the pore structure dramatically. As the Crosslinking agent of RTV silicone rubber and glass fiber surface treatment agent and talk to agents outside of reinforced plastic laminated products in order to improve the mechanical strength, heat resistance, moisture resistance. Methyltrimethoxysilane is used as an acid scavenger, for example in the formation of substituted azulenes from allenylsilanes and tropyl-ium tetrafluoroborate.
