Applications of Hexamethyl Disilazane in Paints and Coatings Industry

For protective paint coatings to be effective for a longer duration of time, they must have good adhesion properties. Adhesion is a widely used term in the field of chemistry and there are several domains that define it differently. When used in reference to paint systems, adhesion is defined by three main properties: adsorption, chemical, … Continue reading

HMDS Applications in the Semiconductor Electronics Industry

Hexamethyl Disilazane is a commonly used pharmaceutical intermediate which is instrumental in the success of various manufacturing processes carried out in large pharma industry. However, not many people know the fact that, HMDS is used heavily in the semiconductor electronics industry as CVD/ALD precursors and photoresist adhesion promoters mainly for ultra-low K dielectrics, low temperature … Continue reading

Silylating reactions using hexamethyldisilazane (HMDS) as an alternative in the analysis of ambers

From the Old ages, the Amber’s unique physical properties have been exploited in the production of tools, ornaments and works of art. The use of derivatisation reagents that transform the polar pyrolysis products into less polar and more volatile compounds, improves the analytical performance and the detection limits of the technique. Tetramethyl ammonium hydroxide (TMAH) … Continue reading

An alternative SEM drying method using hexamethyldisilazane (HMDS) for microbial cell attachment studies on sub-bituminous coal

The use of hexamethyldisilazane (HMDS) as a drying agent was investigated in the specimen preparation for scanning electron microscopy (SEM) imaging of bacterial surface colonization on sub-bituminous coal. The ability of microbes to biofragment, ferment and generate methane from coal has sparked interest in the initial attachment and colonization of coal surfaces. HMDS represents an … Continue reading

Mechanism of Silation of Silica with Hexamethyldisilazane

The silation of silica with hexamethyldisilazane (HMDS) was examined over the temperature range 150−450 °C. The products and sequence of the reactions at the silica surface were determined. The major products are hexamethyldisiloxane (HMDSO) and ammonia, with lesser amounts of nitrogen and methane. No methane is produced during reactions below 300 °C. Ammonia is the … Continue reading

Hydrophobic plasma polymerized hexamethyldisilazane (HMDS) thin film

Hexamethyldisilazane (HMDS) plasma polymerized thin films obtained using low frequency power supplies can be used to make adsorbent films and turn surfaces hydrophobic. The aim of this work was to verify the hydrophobicity and adsorption properties of HMDS thin films (with and without the addition of oxygen, resulting in double or single layer films) obtained … Continue reading
