Dynasylan® HMDS - Hexamethyldisilazane acts as efficient silylating agent in the pharmaceutical industry, as adhesion promoter in the microelectronic industry and as hydrophobation agent, e.g. for fillers. Dynasylan® HMDS is a clear colourless liquid.
Typical Applications
Dynasylan® HMDS is the most commonly used reagent for silylation of protic organic and inorganic materials.
The main applications are:
The main applications are:
- Blocking and protection of hydroxylic groups in natural products
- Stabilization for further modification, formation of volatile products
- Blocking and protection of functional groups in organic intermediates
- The silylated derivatives exhibit improved chemical stability than the basic products and enable chemical reactions which otherwise would not be possible
- Derivatization of protic compounds for analytical in vestigations
- The silylated derivatives are volatile and can be detected by gas chromatography
Benefits at a glance
- Hydrophobation product for e.g. Aerosil products
- Easy and fast hydrophobation
- Silylating agents in the pharmaceutical industry, adhesion promoters in the electronic industry, hydrophobation of fillers
- HMDS is used as a coating material in the semiconductor industry before applying a photoresist. When HMDS is deposited on a surface, it leaves methyl groups behind. These then bond with the OH molecules on the silicon surface and help develop a strong adhesion when a photoresist is applied
