Trimethylethoxysilane (CAS 1825-62-3) — Frequently Asked Questions
What is Trimethylethoxysilane (TMES)?
Trimethylethoxysilane ((CH₃)₃SiOC₂H₅, CAS 1825-62-3) is an alkoxysilane — a moisture-sensitive organosilicon reagent commonly used as a silylating agent and surface modifier.
What are the main uses of TMES?
It is primarily used as a silylating agent, surface modifier for hydrophobicity, in silicone synthesis, deactivating agent in chromatography, and in coatings and adhesives.
What are the key physical properties?
Typical properties: colorless liquid, mild odor, low boiling point, and it is moisture sensitive. Exact numbers (bp, density, vapor pressure) depend on grade — always check the product datasheet.
Is TMES moisture sensitive / does it react with water?
Yes. TMES hydrolyzes on contact with water, producing silanol and ethanol. Handle and store it under dry, inert atmosphere (e.g., N₂) to avoid hydrolysis.
Is Trimethylethoxysilane flammable?
Yes, it is flammable with a low flash point. Treat it as a flammable organic liquid — keep away from ignition sources and follow the SDS guidance for fire precautions.
What are the health hazards of TMES?
Exposure can cause irritation to eyes, skin, and respiratory system. Inhalation, ingestion or skin contact should be avoided; use appropriate PPE.
What personal protective equipment (PPE) is recommended?
Use chemical-resistant gloves, safety goggles, protective clothing, and work in a well-ventilated area. Use respiratory protection if necessary (see SDS).
How should TMES be stored?
Store in a cool, dry, well-ventilated area away from moisture and incompatible substances. Keep containers tightly sealed, preferably under inert gas.
How is TMES packaged and transported?
Supplied in moisture-tight containers (glass bottles or lined metal drums). Transport must follow dangerous-goods regulations — consult SDS for UN number and packing instructions.
What should I do in case of a spill?
Evacuate the area, ventilate, and avoid breathing vapors. Absorb with inert material and collect for hazardous waste disposal. Refer to SDS for details.
What are recommended disposal methods?
Dispose as hazardous chemical waste per local regulations. Do not release to environment. Consult SDS for approved methods.
Can Aure Chemical supply Trimethylethoxysilane?
Yes — contact Aure Chemical sales for available grades, packaging options, COA, SDS and shipping support. Provide required documentation for safe logistics.
Where can I find the authoritative safety information?
Always consult the product Safety Data Sheet (SDS) and applicable local regulations. The SDS contains definitive info on classification, UN number, PPE, first aid, and transport instructions for the exact grade and batch.
