3,3,3-Trifluoropropylmethyldimethoxysilane Usage And Synthesis

Chemical Properties

Colorless clear liquid

Uses

3,3,3-Trifluoropropylmethyldimethoxysilane is mainly used in superhydrophobic coatings and surface treatment of inorganic fillers. It can be used in cosmetics and display or semiconductor devices production.

Toxics Screening Level

The ITSL can be calculated from this acute inhalation value used as a surrogate for the LC50 in the equation in R232(1)(f).The initial threshold screening level (ITSL) for methanesulfonamide is 44 μg/m3 (annual averaging time).
