Description

Tetramethyl-cyclotetrasiloxane is a good impregnant of photoelectric material. It is used to manufacture of modified siloxane with defined hydrogen content and chain quantity. It is also used in production of silicone polymers and acts as a precursor for the deposition of polysiloxane, cyclic siloxane, silicon dioxide, oxycarbide thin films with low dielectric constant for microelectronics and semiconductors.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.

Anwendungen
Tetramethyl-Cyclotetrasiloxan ist ein gutes Imprägniermittel von photoelektrischem Material. Es wird zur Herstellung von modifiziertem Siloxan mit definiertem Wasserstoffgehalt und Kettenmenge verwendet. Es wird auch in der Produktion von Silikonpolymeren verwendet und dient als Vorstufe für die Abscheidung von Polysiloxan, zyklischem Siloxan, Siliziumdioxid und Oxycarbid-Dünnschichten mit niedriger dielektrischer Konstante für Mikroelektronik und Halbleiter.

Löslichkeit
Mischbar mit den meisten organischen Lösungsmitteln. Nicht mit Wasser mischbar.

Hinweise
Nicht kompatibel mit Oxidationsmitteln, Basen und Säuren. Kühl lagern.
