The water-based varnish is mainly composed of water-based resin, solvent and auxiliary agent. Among them, the resin is the most important component, which affects and controls the gloss, adhesion, abrasion resistance, water resistance, scratch resistance, etc. of the varnish coating film. Various properties. The solvent of water-based varnish is mainly water, and the leveling property is good, and it is colorless, non-toxic and tasteless, which is unmatched by other solvents. However, compared with general solvents, water has strong paper fiber wettability, low volatility, slow drying speed, and volatility is greatly affected by environmental humidity. The additives mainly improve the coating properties of water-based varnish and the film-forming properties after glazing. The commonly used additives mainly include solvents (mainly alcohols), leveling agents, substrate wetting agents, thickeners, Wax emulsion, adhesion promoter.
Water-based varnish is colorless, odorless and VOC-free, so it is especially suitable for printing on food packaging with high hygienic requirements. It has high transparency and can be preserved on the surface of printed materials for a long time. Under strong sunlight, water-based varnish will not be ubiquitous. Yellow and discolored. Water-based varnish has strong abrasion resistance, fast film formation speed, rapid drying, and can be completed in a few seconds. The drying equipment is simple (mainly infrared lamp tube and exhaust fan), and the initial investment is small. Water-based varnish is suitable for a variety of processing methods, surface finishing effect is good, can be directly at the water and oil interface for flash powder, flocking, bronzing, bumping, indentation and other second processing.
Printing companies use water-based varnish, not only to use its beautification function, but also because it has a good protective effect, can significantly improve the water resistance, abrasion resistance, light resistance, chemical resistance and anti-fouling of printed materials. Performance, so that prints reduce losses during production, transportation, storage and other processes. In addition, water-based varnish can also achieve some special functions, such as heat and oil resistance, which can be in direct contact with food, and the pizza box is baked at 204 ° C for 30 minutes without change. Another example is the bottoming function. When printing UV gold and silver ink with poor adhesion, it can be ground with water varnish and then printed with UV gold and silver ink to enhance the adhesion strength of the ink.
