NMP is used to produce fine chemicals from mass-produced chemicals.

Applications in the electronics field have expanded in recent years.  NMP's high polarity and high solvency power along with our high purity, high-grade production technology enable the high performance needed in this field.

NMP can dissolve organic and inorganic compounds equally well or better than chlorofluorocarbon solvents.  Therefore NMP is used in various industrial fields as a cleaning or release agent.

NMP is replacing 1,1,1-trichloroethane in metal cleaning applications due to the world-wide environmental pollution problems associated with chlorinated solvents.

1) Electronics:Wax, flux removal

Electronic parts cleaning

Semiconductor parts cleaning

Solvent for lithium battery manufacturing

Semiconductor photo-resist thinner

Color filter photo-resist thinner

2) Automotive:Mold cleaning,Metal (parts) cleaning

3) Chemical:Extract agent (acetylene, BTX, butadiene)

Synthetic resin surface coating solvent

Reaction solvents (PPS, polyimide, etc.)

Equipment washing

4) Pharmaceutical and Agricultural Chemicals:Water-soluble solvent etc.


N-methylpyrrolidone (NMP) is hygroscopic, if moisture content is to be controlled,

keep storage containers tightly closed or under a dry nitrogen atmosphere. 

NMP is a strong degreaser, in the event of skin contact wash immediately with water.
