N-Vinylpyrrolidone (NVP)
Applications:
Primarily used in rapid processing and low-temperature processes for protecting cables, electrical equipment, printed circuit boards, etc.
Applied to enhance elongation and viscosity in low-gloss coatings, improve wood performance, reduce environmental pollution pressure, and maintain curing properties in paper production.
Mainly utilized in metal diluents, cured inks, and cured adhesives.
