N-vinyl pyrrolidone (NVP)


Chemical formula C6H9NO Molecular weight 111.14 Melting point: 13.5 ° C Boiling point: 148 ° C (13.33 kPa) Water soluble: miscible with water, ethanol, ether and other organic solvents Appearance: colorless liquid

1. Plastic

The monomer can be added to the formulation of a UV-curable coating to form a flexible and rigid plastic film. Adding NVP to the radiation medical formula can increase the elongation and viscosity of high gloss and low gloss coatings.

2. Wood

Enhancing product performance, increasing productivity and reducing pressure on environmental pollution are the main drivers of the investigation of the use of scatter-like coatings in the furniture industry. The addition of NVP to the UV-resistant coatings used in the wood flooring industry provides the physical properties of wax-free flooring.

3. Papermaking

UB and EB cured coatings used in paper or board generally require lower viscosity and higher reactivity. NVP meets these criteria by improving fluidity and measurement levels and maintains good cure characteristics.

4. Metal

UV coatings for metals are typically formulated using a cationic vinyl ether/epoxy chemical or heterocyclic system. The function of NVP is to crosslink with vinyl ether or acrylic functional groups to form an excellently active diluent in these systems.

5. Ink

The packaging market uses EB and UV curing technology to speed production and reduce energy consumption. Excellent performance and low odor curing inks play an important role in the screen ink market.

6. Electronic

Electrical equipment manufacturers rely on UV coatings for rapid processing and low temperature processing to protect cables and electrical components as well as printed circuit boards.

7. Adhesive

Strict emission requirements and the need for higher cure rates have prompted the industry to develop a wide range of cured adhesives.
