Handling information
High stability allows catalyst handling on air. Catalyst solution should be used within 2 h from its preparation.
As a result of improving the catalyst production method, the currently offered product (AS2186) no longer contains nitromethane in its structure. The previous version (AS2086) with nitromethane is still available from distributors, but this factor does not affect the product's properties.
Storage information
Long-term storage (>1 week):
Store under inert gas in a cold place (recommended temp. 2 - 8 °C).
Short-term storage (<1 week):
Store under inert gas at ambient temperature.
