          What are the advantages of UVLED coatings cured by UV curing equipment?
          Add Time:2023-12-07
            I believe many people know that UVLED curing machines are used to cure inks,resins,UV adhesives,etc.So what are the advantages of these UVLED coatings?Why use these coatings?Let's take a look below!
            UVLED coating has the characteristics of rapid curing,low-temperature curing,safety and environmental protection,and excellent film-forming performance,which helps to solve many problems in the glossy processing of printed materials and fills many shortcomings of traditional polishing.Its main characteristics are as follows:
            1.VU varnish,which meets safety and environmental protection standards,should belong to solvent-free varnish with a solid content of 100%.After being exposed to light,it is completely converted into effective film-forming substances and has no VOC(organic volatile compounds)emissions.This helps to prevent air pollution,improve the working environment,and reduce the risk of fire.
            2.The production efficiency can be quickly cured in a high-temperature room,which is higher than the general polishing method.Currently,the general curing speed is 50-150m/min,and***can reach 300-500m/min.
            3.UVLED polishing has a wide range of applications.In addition to paper printed products,it can also adapt to various printing carriers,such as aluminum foil,gold and silver cardboard,vacuum aluminum coating,laser film,plastic,synthetic paper,metal,wood,and more.
            4.Excellent film-forming performance:UVLED not only has high glossiness and smoothness,but also after UV curing,it forms a strong and tough network structure,which has excellent wear resistance,water resistance,heat resistance,scratch resistance,chemical resistance,and solvent resistance,which is difficult to compare with other glossy coatings.
            5.The UVLED polishing device saves much less energy and space compared to the heating and drying channels for solvent polishing,and also saves a lot of energy consumption.It is very suitable for online polishing and automated assembly line operations.
            6.Stable coating performance:Due to the absence of volatile solvents in VU polishing,it is not easy to cause viscosity changes during the coating process,so the coating stability is good and the dosage is relatively low.
            7.The resin used in solvent based glossy coatings to avoid product adhesion is mostly thermoplastic resin,which is greatly affected by factors such as temperature,humidity,coating thickness,and drying conditions,which can easily cause varying degrees of adhesion in the product.However,if the light curing coating meets the requirements,there is no need to worry about adhesion problems.After polishing,it can be stacked or processed at will.
            8.UVLED polishing can replace plastic composite and plastic film composite technology has been widely used in many neighboring areas both domestically and internationally.It can completely avoid the phenomena of edge warping,foaming,wrinkling,delamination,etc.that often occur in the lamination process.It can also recycle paper and reduce environmental pollution caused by the inability to regenerate lamination products.
