七、QUALITY SPECIFICATION OF N-vinylpyrrolidone
1、Plastics: the unit can be added to the recipe for UV curing coatings, formed of flexible and rigid plastic film. Add NVP in radiation medicine formula can improve further rate as the high light and low light coating, viscosity, etc.
2、Wood: enhanced product performance, increase productivity and reduce pressure on environmental pollution, is scattering coatings used in the furniture industry to investigate major motivations. Wooden flooring industry in the use of UV coatings can add NVP provides no wax floor equivalent of physical characteristics.
3、Paper: paper and cardboard used in the UB and EB cured coatings, General requirements of low viscosity and high reactivity. NVP through improved liquidity and measurement standards to meet these standards, and maintains good curing characteristics.
4、Metal: UV coatings for metal in general using cationic vinyl ether/oxide composition formula in chemistry or heterocyclic, NVP or acrylic and vinyl ether functional group is the function of linking these systems form a good reactive diluent.
5、Inks: packaging using UV and EB curing technology in the market, to speed up production and reduce energy consumption. Better performance and less smell of ink in screen printing inks cured occupy a substantial share of the market.
6、Electron:electrical equipment manufacturer relies on rapid processing and low temperature process of UV coating to protect the cables and electrical components and printed circuit boards
7、Adhesives: strict emission requirements and must be a high cure rate contributed to the industrial development of a series of wide range of curing adhesives.
