| Hazard Information | Back Directory | [Hazard]
A poison by ingestion. A moderate eye irri-tant. | [Description]
Methyldimethoxysilane, reactive silane containing both Si-H and methoxy functional groups. The SiH group can be utilized for hydrosilylation to form methoxysilyl functional materials. Modification by hydrosilylation can bring the benefit of moisture cure or crosslinking by reactive methoxy groups. | [Chemical Properties]
Colorless clear liquid | [Uses]
Modifications by hydrosilylation reaction. | [Flammability and Explosibility]
Highlyflammable | [Toxics Screening Level]
The ITSL for methyldimethoxysilane is 92 μg/m3 based on an annual averaging time. |
