Tetraethyl orthosilicate 40 Description

CFS-062, Tetraethyl orthosilicate 40 is the ethyl polysilicate with a minimum SiO2 content of 40%. It is also named Tetraethoxysilane hydrolysate or Ethyl silicate 40 and known as abbreviated TEOS 40 or Si-40. CFS-062 is mainly used as in important intermediate for a wide range of applications. It is the equivalent of Dynasylan® SILBOND® 40.

Tetraethyl orthosilicate 40 Application

CFS-062 is an important material for sol-gel processing. It can be used as a crosslinking agent, a binder or a drying agent in adhesives and coatings, especially suitable for anti-corrosion coatings, zinc-rich coatings, chemicals-resistance coatings and heat-resistance coatings.
CFS-062 can be used to deposit silicic acid and improve the bonding to various inorganic substrates such as metals, glass, fibers, inorganic fillers and pigments. It can improve mechanical properties as well as chemicals and thermal stability of the composites.
CFS-062 can be used for the synthesis of cold curing silicone rubbers.
CFS-062 can be used to replace CFS-104(Tetraethyl orthosilicate, or TEOS) with higher SiO2 content to reduce costs.

Tetraethyl orthosilicate 40 Packaging

CFS-062 is offered in 25L PE pails, 200L PVF steel drums and 1000L IBC totes.
Please contact Co-Formula team for any special packaging request.

Tetraethyl orthosilicate 40 Storage

CFS-062 should be stored in a cool, well-ventilated place, and avoid exposure to humidity.
CFS-062 should be stored in its original containers and used up as soon as possible after opening.
When stored in a strictly sealed and unopened container, CFS-062 has a shelf life of 12months.
