N-vinylpyrrolidone NVP

NVP: At room temperature, it is a colorless or light yellow transparent liquid with a slight odor, melting point 14℃, easily soluble in water and other organic solvents, and its chemical properties are active and easy to hydrolysis and polymerization. NVP monomer is the active diluent of photocurable or electron beam curable coatings, widely used in pharmaceutical, cosmetics, coatings photocuring agent, ink, binder, glue raw material.

CAS number: 88-12-0

Molecular formula: C6H9NO

CTFA name N-vinyrrolidone

Plastics and adhesives

Plastic: This monomer can be added to the formulation of UV-curable coatings to form a flexible and rigid plastic film. The addition of NVP to radiation medical formulations can improve the elongation and viscosity of high-light and low-light coatings. Adhesives: Stringent emission requirements and the need for high curing rates have prompted the industry to develop a wide range of curing adhesives.

Timber

Enhancing product performance, improving productivity and reducing the pressure on environmental pollution are the main reasons for the use of scatter coatings in the furniture industry to be investigated. The addition of NVP to anti-ultraviolet coatings used in the wooden flooring industry can provide comparable physical properties to wax-free flooring.

papermaking

UB and EB curing coatings used in paper or paperboard generally require lower viscosity and high reactivity. NVP meets these standards by improving fluidity and measurement levels, while maintaining good curing properties.

metal

UV coatings for metals are generally formulated using cationic vinyl ether/epoxy chemical or heterocyclic systems, and the function of NVP is to cross-link with the functional groups of vinyl ether or acrylic acid to form an excellent active diluent in these systems.

Printing ink

The packaging market uses EB and UV curing technologies to speed up production and reduce energy consumption. Cured inks with NVP solvent have excellent properties and less odor, and occupy an important share in the screen ink market.

corpuscle

Electrical equipment manufacturers rely on rapid processing and cryogenic processing of UV coatings using NVP to protect cables and electrical components as well as printed circuit boards.
