Description of key information
Physical state: crystalline solid, but used in a non-solid form (liquid)
Key value for chemical safety assessment
- Physical state at 20°C and 1013 hPa:
- 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.
