N-Vinylpyrrolidone properties

N-Vinyl-2-pyrrolidone NVP CAS 88-12-0 is a colorless liquid, easy to poly synthesis of polyvinyl. It can be mixed with water, ethanol, ether and other organic solvents, easy to copolymer with other ethylene compoundsa clear to slightly yellow liquid, crystallization under 13℃. It’s easy to hydrolyze and polymerize itself but It can remain as liquid at room temperature for extended periods. Usually,stabilized with NaOH or TMHPO as polymerization inhibitor.

Specification of N-Vinylpyrrolidone

Appearance       Colorless to slightly yellow liquid

Application of N-Vinylpyrrolidone

Plastic

The monomer can be added in the UV curing coating formula, forming flexible and rigid plastic film. NVP is added in the radiation medical formula can improve the highlights and the extension of low light coating rate, viscosity, etc.

Wood

Enhance the product performance, improve productivity and reduce the pollution to the environment pressure, is the use of scattering conformal coating in furniture industry need to investigate the main factors. Ultraviolet resistant coatings used in the wooden floor industry add NVP no wax the floor can provide equivalent physical properties.

Paper

Used in paper or cardboard UB and EB curing coating, general requirements with low viscosity and high reactivity. NVP by improving the liquidity and measurement standard and meet these standards, and maintain good curing characteristics.

Metal

Metal with UV coating using cationic vinyl ether/epoxy chemical formula or heterocyclic system composition, the function of NVP is and vinyl ether or acrylic acid functional groups linked these system form a good active diluent.

Printing ink

Using EB and uv curing technology, packaging market to speed up production speed and reduce energy consumption. Good performance and less odor curing ink on silk screen printing ink occupied the important share in the market.

Electronic

Electrical equipment manufacturers rely on UV coating fast processing and low temperature process to protect the cables and electrical components and printed circuit board.

Adhesive
