Tetrakis(2-butoxyethyl) orthosilicate (TBEOS) is a colorless, transparent liquid that acts as a crosslinking agent for silicone sealants. It is a silicon ester and contains an oxygen bridge from a silicon atom to an organic group. TBEOS is an excellent crosslinker for room-temperature vulcanizing silicone sealants.
No public registered data
There are no publicly available data on the toxicity of Tetrakis 2-butoxyethlyl orthosilicate. This compound has a vapor pressure of 1.88 mm Hg(3) and is not expected to adsorb to sediment or suspended solids. Consequently, it may be volatile and vaporize from water and moist soil surfaces.
The chemical TEOS is an ester of orthosilicic acid and is found naturally in small amounts. This substance has several alternative names, including silicon tetraethoxysilane. The ECHA has no publicly registered data for Tetrakis 2-butoxyethyl orthosilicate. However, there is some limited information on this substance.
It is a colorless, odorless liquid with a flash point of 125degF. It is less dense than air and water, making it a vapor that is easily diluted. Tetraethylorthosilicate was studied in rats at a dose of 0.333 g/kg daily, and was found to accumulate in the glandular and muscle layer of the stomach.
No public registered data on the types of manufacture
Currently there is no public information available from the ECHA on the types of manufacture of Tetraki’s butoxyethyl orthosilicate. However, it is an organosilicon substance and is used in several products. It is found in a wide range of applications, including adhesives, sealants, and polymers. Releases of this substance into the environment can occur through industrial use and through the formulation of mixtures and materials.
No public registered data on the routes by which Tetrakis 2-butoxyethyl orthosilicate is most likely to be released to the environment
There is no public registered data on the routes by which Tetrikis 2-butoxyethyl-octasilicate is most likely to be released into the environment. In the absence of such data, it can be assumed that the chemical is primarily released to the environment by combustion. The chemical’s release potential is low as it readily degrades into ethanol and silicic acid. The half-life of TEOS is about 25 days.
TEOS, or tetrakis-2-butoxyethyl silicate, is a colorless, odorless liquid. It is the most common alkoxide of silicon. TEOS reacts with ethanol and EtOH, which is a volatile coproduct of diethyl ether.
The chemical CAS:41051-80-3 is most effective when the hydrogen is dissolved in an organic solvent, such as oil or fuel. It can be blended into base fuel. It is also suitable for fuel additives. It has been used in the production of plastics, synthetic rubber, and lubricants. The chemical is a highly reactive, volatile organic compound and can degrade in a variety of environments.
No public registered data on the routes by which this chemical is most likely to be released to the environment. The substance is a liquid and requires appropriate containment and good work practices. The tonnage per use is given below, which corresponds to tonnage at the site for widespread uses. The exposure assessment is based on the hazard conclusions of CSA section 7.
