N-Vinyl-2-pyrrolidone description and usage Description
— a colorless or slightly yellow transparent liquid;
— soluble in water or other organic solvents;
— easy to hydrolyze and polymerize;
N-Vinyl-2-pyrrolidone Usage
–As important monomers of homopolymers and copolymers; most of their copolymers and homopolymers have good film strength, dye compatibility, rigidity and viscosity;
–Plastic industry: used in UV-curing coating formulations to form flexible and rigid plastic films; used in radiation medical formulations to provide elongation and viscosity of high gloss and low gloss coatings;
–Electronics industry: for UV coatings, protecting cables and electrical components and printed circuit boards by performing fast processing and low temperature processing;
–Wood industry: The addition of NVP to the UV-resistant coatings used provides the physical properties of wax-free floors.
–Metal industry: formulated with a cationic vinyl ether / epoxy chemical or heterocyclic system to form an excellent reactive diluent;
–Other industries: Widely used in the fields of paper, ink and adhesive
