| Other Standards Regulations and Guidelines | The subchronic (14-week), whole-body inhalation study (6 h/day, 5 days/week) in F344 rats was used as the critical study for the derivation of the Workplace Environmental Exposure Level (WEEL). The No-Observed-Adverse-Effect Concentration (NOAEC) of 100 ppm (605 mg/m3) was used as the point of departure (PoD). Adjustment factors for subchronic to chronic extrapolation and intra-individual variability were applied to the NOAEC to develop the health-based WEEL value of 10 ppm as the 8-hour time-weighted average (TWA). |

シランカップリング剤
使用
VTMS may be used to provide superhydrophobicity to different materials like TiO2, talc, kaolin, magnesium oxide nanoparticles, ammonium phosphate and PEDOT. It modifies the surface by capping the material and creates a protective layer that is water resistant and can be used in major coating industries.
一般的な説明
Vinyltrimethoxysilane (VTMS) is a silane coupling agent with silicon and hydroxyl groups that can be used to enhance the wettability and improve the superhydrophobic characteristics of different composites.
