Tetra methyl ortho silicate - COUPSYL® TMOS

Tetra methyl ortho silicate, also known as tetra methoxy silane, is a member of the alkoxy silane family and is a component of organosilicon. It is a flammable, colorless liquid with a medium boiling point and low viscosity. It also has a pungent odor and is very toxic. Tetra methoxy silane, which is the smallest member of the alkoxy silane family, has four methoxy groups . As a silane coupling agent dissolves in alcohols and most common solvents and is hydrolyzed in contact with moisture to form SiO2 powder and methanol alcohol.

Tetra methyl ortho silicate is the main and cheapest substance in the silane family. It is the most widely used chemical in this family And is used in most different industries.

Physical and chemical properties

Application of Tetra methyl ortho silicate - COUPSYL® TMOS

The following are some of the main uses of Tetra Methoxy silane.

Production of silicate aerogels

As a solvent for resins and silicone adhesives

Production of sol-gel

Production of pure SiO2 powder Production of silica fume

Production of erosil silicate

As a coupling agent in various composites and polymers

Maintenance method

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.

Packaging and shipping

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.
