Tetra methyl ortho silicate (TMOS) is a colorless, flammable, and highly toxic liquid from the alkoxy silane family. It has low viscosity, a pungent odor, and hydrolyzes with moisture to produce SiO₂ and methanol. As a silane coupling agent, it dissolves in alcohols and common solvents and is the main, most widely used, and least expensive compound in the silane family, applied across many industries.

This substance is flammable and its vapors are toxic.
Tetra methoxy silane or methyl silicate should be stored in the main container in a sealed state in a dry and humid environment at a temperature of 10-30 ° C to prevent evaporation and hydrolysis. In case of contact with skin, wash immediately with plenty of water. See a doctor if swallowed. This substance is flammable and its vapors are toxic.
Tetra methoxy silane can be stored in plastic or metal tanks. This material should be kept away from flame or spark sources. This product is offered in 20 and 200 kg plastic tanks. Due to the absorption of moisture, barley should be kept in the main containers as a seal.
Production of silica aerogel and as a solvent for resins and silicone adhesives
Production of sol–gel
Production of pure SiO₂ powder
Production of silica foam
This substance is colorless and liquid. It causes severe irritation, burning, dryness, and inflammation of the skin. It causes irritation to the digestive system and respiratory tract. Acids, oxidizers, and water react strongly with it.
Contact with the eyes causes severe eye irritation.
Contact with the skin causes dryness, cracking, and skin inflammation. This substance can also be absorbed through the skin.
Inhalation causes irritation to the respiratory system and prolonged exposure may cause difficulty in breathing.

Store in the original sealed container in a dry, low-light environment at 15–40 °C to prevent evaporation and hydrolysis.
Avoid contact with skin; wash immediately with water if contact occurs.
In case of ingestion, seek medical attention.
Keep away from flames, sparks, and heat sources, as the product is flammable and its vapors are toxic.
The product can be stored in plastic or metal containers, typically in 20 kg or 200 kg drums, but must remain sealed to prevent moisture absorption.
