trimethoxyethoxyvinylsilane GPS Safety Summary - Evonik ...

Exposure
Human / Environment
There is no exposure to humans from Trimethoxyethoxyvinylsilane via the
environment, as the substance is highly reactive and, thus, immediately
hydrolyzes. Manufacturing occurs under controlled conditions, with releases
to air and waste water according to the existing legal and regional
permissions. Releases to the environment during use and handling are
limited by use of appropriate measures as mentioned in the Safety Data
Sheet and described under Risk Management Recommendations. Due to the
reactive nature of Trimethoxyethoxyvinylsilane when in contact with water, or
indeed with silanols, under the conditions used to prepare silicone polymers
and resins, it can be assumed that they are completely consumed in the
hydrolysis/condensation process,
In those cases where Trimethoxyethoxyvinylsilane in sealants is used in
professional applications, the Silane has invariably hydrolyzed and
condensed to form Siloxane oligomers and polymers and there is no
exposure from the end product.
