Product Name:3-Isocyanatopropylmethyldiethoxysilane
English Name:3-Isocyanatopropylmethyldiethoxysilane
CAS No.:33491-28-0
Aliases:3-(Diethoxymethylsilyl)propyl isocyanate, Diethoxymethylsilylpropyl isocyanate, 3-Isocyanatopropyl(diethoxy)methylsilane
Molecular Formula:C9H19NO3Si
Physical Properties:Colorless to light yellow transparent liquid with a pungent odor. Boiling point approximately 210-215°C, flash point approximately 85°C, density approximately 0.98 g/mL at 25°C, refractive index approximately 1.422. Soluble in organic solvents such as alcohols, ketones, and aromatic hydrocarbons. It hydrolyzes readily in contact with water or moisture, releasing carbon dioxide, and should be stored sealed and dry.
Uses:Mainly used as a silane coupling agent to improve the interfacial adhesion between inorganic fillers and organic polymers, widely applied in coatings, adhesives, and sealants. It also serves as an organic synthesis intermediate for preparing isocyanate-containing silane-terminated polymers, polyurethane-modified silicone oils, and functional silane derivatives.
