Uses:
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 radiation medical formulations 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.
Packaging and storage:
200kg/plastic drum, sealed, protected from light, low temperature, stored under neutral or weak alkaline conditions; when handling, lightly load and unload, keep the package intact and prevent leakage. When swaying, storing too long or photoelectrically illuminating, NVP can be semi-polymerized, so distillation should be carried out before use to prevent polymerization.
Remarks:
· Dissolved in water, methanol, ethyl acetate, ethanol, dichloromethane, hydrocarbons (hydrocarbon
· Stored in a sealed, dark, low temperature, neutral or weakly alkaline condition
· NVP is poisonous and slightly odorous. It is corrosive to rubber and leather. Do not splash into the eyes or touch the skin.
· NVP can be semi-polymerized when shaken, stored too long or photo-irradiated, so it should be distilled before use to prevent polymerization.
