Fumion FAA-3-SOLUT-10 is an anion exchange ionomer that acts as a binding agent to hold the platinum, membrane, and gas diffusion layer together when using Fumatech anion membranes. Fumion FAA-3 solution comes in a brown, transparent N-methyl-2-pyrrolidone (NMP) solvent solution. The solution is ready to use and requires no additional additives.
• Ionomer Type: Anion Exchange Ionomer
• Polymer Type: Polyaromatic Polymer
• Appearance / Color: Brown, Transparent Solution
• Solvent: N-methyl-2-pyrrolidone (NMP)
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.
