Stability

• Atmospheric moisture and carbon dioxide reacts with KHMDS to produce potassium hydroxide and potassium carbonate. Hexamethyl disilazane is liberated from these reactions. The solution becomes cloudy and develops color. KHMDS solution should be stored in a cool place away from heat, sparks and flame.

Technical Details & Test Data

Sampling Instructions

• The product is packed under dry nitrogen with positive pressure of nitrogen inside the drum.
• The quality of the product deteriorates very fast if exposed to atmosphere even for a brief period.
• While sampling, please ensure that the sample is taken out under dry nitrogen in a Pre-weighed stoppered bottle and analysis is done immediately.
• After sampling, close the container securely after putting positive nitrogen pressure in the drum. This is very important so that the product does not deteriorate on storage.
