Description
Liquid; [Reference #1] Colorless liquid; [Alfa Aesar MSDS]
Sources/Uses
Used as a coupling agent for filled composites and industrial goods (textile goods); Used in closed systems to prevent loss due to rapid hydrolysis; [Reference #1]
Comments
Rapidly hydrolyzed producing 3 moles of methanol for every mole of silanetriol; Methanol is expected to cause any toxicity observed; Not a skin sensitizer in guinea pigs; A repeated-dose inhalation study produced no adverse effects at concentrations up to 100 ppm; Clinical observations in a micronucleus assay of mice include ataxia, tremors, prostration, myoclonic jerks, and vocalization; No reproductive or developmental toxicity observed in an inhalation study of rats at concentrations up to 100 ppm; [Reference #1] Reacts with water evolving methanol; A skin and strong eye irritant; [Alfa Aesar MSDS] See "Methyl alcohol."
