Note: 1. Compression Ratio: The ratio of the cross-sectional area of the resin in the extrusion cylinder (S1) to the cross-sectional area of the resin at the die opening (S2), i.e., R.R = S1/S2.
4. Applications
- Dry-process/wet-process battery electrodes (binder), electronic components, chemical pipelines, non-stick coatings
5. Usage Instructions
- Direct Use or Dilution: Can be applied as-is or diluted with deionized water.
- Mixing Process: Add to powder in reactor—high-speed stirring won’t break emulsion.
- Slurry Control: Adjust water content to achieve desired viscosity.
- Final Steps: Sieve, degas, and discharge slurry after dispersion.
- Storage: Store at low temperature; optimal temperature: 19°C
