Uses of N-Methylpyrrolidone (NMP)


N-Methylpyrrolidone (NMP) Instruction:

N-Methylpyrrolidone (NMP) is an organic substance with the chemical formula C5H9NO, a colorless to light yellow transparent liquid with a slight ammonia odor, miscible with water in any proportion, soluble in various organic solvents such as ether, acetone and esters, halogenated hydrocarbons, aromatic hydrocarbons, etc., and almost completely mixed with all solvents.


N-Methylpyrrolidone (NMP) Storage Method:

Store under dry inert gas, keep the container sealed and store in a cool, dry place.

N-Methylpyrrolidone Handling Precautions:

Avoid exposure: special instructions need to be obtained before use. Avoid contact with skin and eyes. Avoid inhalation of vapors and fumes. Keep away from sources of ignition. -Smoke and fire are strictly prohibited. Take measures to prevent static build-up.

N-Methylpyrrolidone Storage Precautions:

Store in a cool place. Keep containers tightly closed and store in a dry, ventilated place. Opened containers must be carefully resealed and kept in an upright position to prevent leakage. Air-filled storage,moisture-sensitive.

NMP Personal Protective Equipment:

Eye/Face Protection: Safety glasses with protective edge shields meet EN166 requirements. Use equipment tested and approved by official standards such as NIOSH (USA) or EN 166 (EU) for eye protection.
Skin protection: Wear gloves to take gloves must be inspected before use.
Body protection: impermeable clothing, the type of protective equipment must be selected according to the concentration and amount of hazardous materials in the particular workplace.
Respiratory protection: If the hazard assessment shows that an air-purifying gas mask is required, use a full-face multi-purpose gas mask (US) or an ABEK-type (EN14387) gas mask cartridge as an alternate for engineering control. If a gas mask is the only means of protection, use a full facepiece air-fed gas mask. Respirators use respirators and parts that have been tested and passed government standards such as NIOSH (US) or CEN (EU).
