    2.Instructions for use:
    2.1. Recommended dosage of Sinodur® 2520 LFP system: 1.8%-2.5%; Note: PVDF is mainly used to bond positive electrode material particles, and the dosage is mainly determined based on the density and specific surface area of the positive electrode material.
    2.2. Instructions for use When using wet bonding, quickly mechanically stir for 3-4 hours. If the equipment stirring rate is slow or the stirring is uneven and cannot completely dissolve, the stirring time can be increased by 0.5-1.0 hours appropriately. After the PVDF is completely dissolved, proceed to the pulping process. When dry pulping, mix the positive electrode material, carbon black, and PVDF for 0.5-1 hour, add solvent kneading for 20-40 minutes, then high-speed stir for 3-4 hours, adjust the slurry viscosity output according to coating requirements.
    2.3. Product storage This product is recommended to be stored in dry and ventilated conditions, avoiding light and heat.
    2.4. Others For other special usage and storage conditions, please communicate with our relevant personnel in a timely manner.
