Description

ApplicationCross-linkable solid polymeric electrolyte.
 Product becomes cross-linked with 800-1,000 mJ/cm2 UV exposure after drying at 110 °C for 10-15 min; or at 140-150 °C for 1 min.
Packaging25, 100 mL in glass btl
Preparation NoteTreat with 0.5M Sulfuric acid for 20 min to strengthen after cross-linking.
 To cast a film:
1. Concentrate solution to 600 centapoise viscosity (typically 6-9 wt.% polymer).
2. Preheat the casting surface to 35 °C. A clean, flat PTFE-coated glass surface is recommended.
3. Secure a silicone release liner to the casting surface.
4. Place a small drop of the polymer solution on the release liner.
5. Draw the polymer solution down the release liner.
6. Dry the film for 30 min. For controlled evaporation it is recommended to cover surface with aluminum foil that has been perforated with small pinholes.
