Product Information
Product code:D-120
Chemical name::TETRA PROPOXY SILANE
Molecular Formula:C12H28O4Si
Molecular Weight:264.43
CAS No.:682-01-9
Properties
D-120(also known as propyl orthosilicate) can be used as a crosslinking agent in silicone rubber, and can also be used as a modifier in organic and inorganic resins, and the propoxy group in propyl orthosilicate replaces the ethoxy group in ethyl orthosilicate, so its hydrolysis rate is slower than ethyl orthosilicate.
Technical Data
Note: the above data is for reference only, cannot be as a technical specification.
Reactivity
D-120 is difficult to hydrolyze, and it is difficult to hydrolyze water without acid-base catalyst after contact with water. The addition of hydrolytic catalysts (inorganic/organic acids, ammonia or amines) can accelerate the hydrolysis reaction, resulting in the formation of silanol and higher condensation products.
Application
D-120 is mainly used as a crosslinking agent for RTV-2 silicone sealant .
D-120 can be used as intermediate of sol-gel process.
