Dynasylan SILBOND Pure - Description
Dynasylan SILBOND Pure is a clear, low-viscosity liquid that is essentially pure tetraethyl orthosilicate monomer (99.0%). Dynasylan SILBOND Pure is used as a building block for zeolites and catalyst carriers, crosslinking agent, chemical intermediate, clear-coat component, and in any other application requiring pure TEOS monomer.

Dynasylan SILBOND Pure is immiscible with water, so hydrolysis requires the use of a co-solvent such as ethanol. Suitable catalysts are mineral acids or ammonia, or even acetic acid and amines.
Partial hydrolysis gives hydrolysates of Dynasylan SILBOND Pure whose shelf-life depends on the amount of water and solvent used. The amount of water determines the activity of the hydrolysate. Activity and shelf-life are inversely proportional. The correct choice for the amount of water can give hydrolysates, which have a shelf life of up to a year (from the time of manufacture).
