Frequently asked questions
What is ethyl silicate-40 (ETS-40 / TEOS) and what is it used for?
Ethyl silicate-40 (ETS-40, tetraethyl orthosilicate / TEOS) is a silicate binder raw material containing 40-42% silicon dioxide by mass. It is mainly used to obtain the binder for ceramic shell moulds in investment casting and refractory applications, as well as in heat-resistant coatings and binder production.
In what packaging is ETS-40 supplied, and is it ex-stock?
ETS-40 is supplied in steel drums, containers and rail tank cars; in drums it is stored in enclosed areas not exceeding 30°C and has a shelf life of 12 months from manufacture. KORKİMYA offers ex-stock delivery and fast shipping, shortening lead times compared with importing from China.
Is ETS-40 KKDİK-registered and is a Turkish SDS provided?
Yes. KORKİMYA supplies ethyl silicate-40 as KKDİK-registered and provides a Turkish Safety Data Sheet (SDS) with every shipment. It ships under UN 1292, and a certificate of analysis (CoA) and technical data sheet (TDS) are available on request.
How can I get a sample and a quote for ETS-40?
