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 photo resist in the production of LCD materials;
(3) As solvent in pharmacy;
(4) Cleaning of precision instruments and circuit board. Specification: | Items | electronic grade | Unit | Testing method | Purity | 99.90min | % | GC | Moisture | 0.02max | % | Karl fischer method | Chroma | 10max | APHA | Colorimetry |
