solid

Additional information

Methylsilanetriyl triacetate is manufactured as a low melting crystalline solid; it has a melting point of 40 - 43°C and a boiling point of 206 - 220°C. However, the substance is used in a non-solid form and is moisture sensitive. The commercial material of the substance as supplied within the EU is as a liquid.
