Products Description
What is Octamethyltrisiloxane ?
Octamethyltrisiloxane is a colorless liquid with low viscosity and low surface tension. Its CAS number is 107-51-7, its chemical formula is C8H24O2Si3, and its molecular weight is 236.53. Its density at 25 degrees Celsius is 0.82 g/mL (literature value), its melting point is -82 degrees Celsius (literature value), its boiling point is 153 degrees Celsius (literature value), and its flash point is 99 degrees Fahrenheit. Its solubility in water at 23 degrees Celsius is 34 micrograms per liter, and its vapor pressure at 25 degrees Celsius is 5.3 hPa. It is slightly soluble in chloroform, slightly soluble in methanol, and soluble in dimethyl sulfoxide (DMSO). Octamethyltrisiloxane has good chemical stability and is insensitive to acids, bases, oxidants, and most organic compounds. The compound has a low surface tension and can spread quickly on the surface to form a thin and uniform coating. It is also volatile, has good diffusivity, and can be mixed quickly with other compounds in many applications.
