Uses:

As a high-selective polar solvent and nitrogen heterocycle compound, NMP has such advantages as non-toxicity, high boiling point, low corrosion, high solubility, low viscosity, low volatility and good stability and high selectivity.

N-Methyl-pyrrolidone(electronic grade) is mainly used in such fields as:
(1) As solvent of poly(1,1-difluoro-Ethene); or electrode's accessory material of lithium ion battery.
(2)As remover liquid of photoresist; in the production of LCD materials;
(3)As solvent in pharmacy;
(4)Cleaning of precision instruments and circuit board.

Storage and transportation:

Store in cool and airy place; keep away from fire and heat; handle with care; avoid leakage.
