Question 1

What are the main applications of NMP in the coatings industry?

Accepted Answer

NMP is the preferred solvent for high-performance polymer coatings including polyamide-imide (PAI), polyimide (PI), polysulfone, and PVDF coatings for wire enameling and heat-resistant applications. It is also used as an active ingredient in solvent-based paint strippers due to its powerful penetrating and solvating capability.

Question 2

Is NMP subject to regulatory restrictions in Europe?

Accepted Answer

Yes. NMP is classified as a reproductive toxin (Repr. 1B, H360D) under EU CLP Regulation. Under REACH SVHC/Authorisation list restrictions (effective 2020), industrial use requires occupational exposure controls with a DNEL of 14.4 mg/m³ (8h TWA, inhalation) and 4.8 mg/m³ for women of childbearing age. Formulation customers should review their downstream use obligations.
