UVLED coating glazing has the characteristics of fast curing, low temperature curing, safety and environmental protection, and excellent film forming properties. It helps to solve many problems in the gloss processing of printed products and fills many deficiencies in traditional glazing. Its main features are as follows:
1) The safety and environmental protection standard VU varnish should be a solvent-free varnish with a solid content of 100%. That is, it is completely converted into an effective film-forming substance after being exposed to light, and there is no VOC (organic volatile) emission, which helps prevent atmospheric pollution and improve operations Environment to reduce the risk of fire.
2) High production efficiency It can be cured quickly in the greenhouse, which is more efficient than the general glazing method. At present, the general curing speed is 50-150m / min, and the fastest can reach 300-500m / min.
3) Wide range of application In addition to paper printed matter, UVLED glazing can also be adapted to many substrates, such as aluminum foil, gold and silver cardboard, vacuum aluminum coating, laser film, plastic, synthetic paper, metal, wood and other printing carriers.
4) Excellent film forming performance UVLED glazing not only has a high degree of gloss, flatness and smoothness, but also has a strong body network structure after being cured by ultraviolet light, so it has excellent wear resistance, water resistance, heat resistance and resistance Scratch, chemical resistance and solvent resistance, which is difficult to compare with other glazing coatings.
5) Energy-saving and floor space The area of ​​UVLED glazing device is much smaller than that of the heating drying tunnel for solvent glazing, and the energy consumption is much less. It is very suitable for online glazing and automated assembly line operations.
6) Stable coating performance Since VU glazing does not contain volatile solvents, it is not easy to cause changes in the viscosity of the coating process, so the coating stability is better and the dosage is less.
7) It can avoid product adhesion. The resin used in solvent-based glazing coatings is mostly thermoplastic resin. Due to factors such as temperature, humidity, coating thickness and drying conditions, it is easy to cause blocking phenomena of varying degrees of products, and light curing Only if the light conditions of the coating meet the requirements, there is no need to worry about adhesion problems. After coating, it can be stacked or arbitrarily processed.
8) UVLED glazing and plastic film replacement technology can be used in many neighborhoods at home and abroad, it can completely avoid the warpage, blistering, wrinkling, delamination and other phenomena that often occur in the coating process, and The paper can be recycled to reduce the environmental pollution caused by the non-regeneration of the film-covered products.
