Fumion FAA-3-SOLUT-10 Technical Specification Sheet

Delivery and Handling:

Keep solution package closed / sealed when unused. Open only for direct use and process immediately after opening. Store and handle in a clean and dust-free area. Always wear protective gloves and safety goggles when handling the solution. The fumion® solution contains NMP and a polyaromatic polymer with quaternary ammonium functional groups (counter ion bromide).

Shake before use. Admixture of alcohol or water to the fumion® solution may precipitate the ionomer. However, diluting the solution with polar organic solvents such as NMP, DMAc and DMF is feasible without precipitation. Recommended storage conditions: Store in delivery containers (closed), avoid direct exposure to sunlight and humidity. Storage temperature for long term storage: 5 °C (keep cool), short term storage for some weeks at 15 - 35 °C possible. Expected shelf life: A shelf life of 4 months at 25 °C (solution tends to gelation).

If you have any concerns about storage, chemical stability, pre-treatment or before proceeding, please feel free to contact us for further information.

Please note that a current lead time of two to three weeks is to be expected.
