Application of WS Varnish

WS Varnish was put into operation at Xinxiang Yinghui, marking a new stage in packaging and printing lacquer technology for environmentally friendly recycling, low cost and high quality. WS Varnish, WS Varnish allows us to see the coating of ancient varnish products to glazing technology, and to glazing the coating to “two in one” (ie to make the base oil and then UV varnish. ) A qualitative leap between new glazing oil technologies. 

With the improvement of glazing level, especially the reduction of coating cost, especially from room temperature curing, to UV curing, to the current high temperature (200 ~ 250 °C) room temperature curing coating and chlorine dioxide content shall not exceed 1.1 The technical barriers in the field of packaging and printing will surely set off the attention and research and application innovation of WS Varnish products. In order to make the packaging and printing industry colleagues better use WS Varnish, the authors introduce the following characteristics of their applications:

WS-1 Varnish is UV Varnish. This product is based on epoxy acrylate resin, and is a mixture of photoinitiator, polymerization inhibitor, leveling agent and cheap organic solvent. The product overcomes the defect of poor adhesion of traditional UV coating in the wet coastal areas, dry areas in the northwest and the rainy season in the Central Plains, and is also about 10% to 30% lower than the cost of UV varnish on the market. Packaging and printing operators can achieve the same adhesion as UV oil and base oil without special treatment methods. 

WS-6-2 Varnish is a relatively simple glazing product currently used. It only needs a UV coating to overcome the tedious process of using UV oil in the past and the power consumption and consumption of two oiling and polishing. Varnish, manpower, and defects in the glazing site. In addition, after using WS62, the glossy packaging and printing products can be recycled and reused, while at the same time overcoming the major drawback of the conventional UV-coated packaging that is difficult to reproduce. 

WS-2 Varnish is based on the traditional bottom oil and is made entirely of domestically produced materials, especially benzene-free, chlorine-free, non-carcinogenic and pure green varnish. The method of use is the same as traditional varnish. However, due to the high content of low viscosity resin WS2, Varnish high viscosity, need to polish the packaging and printing products without the need for coating, just infrared at room temperature or about 40 °C hair dryer can be. Overcame the long-time UV light oil when the UV damage to the operator's vision and the first scratch and then the UV light oil cumbersome production process. In addition, the product is alcohol soluble or water soluble, giving packaging and printing companies greater choice. 

WS-3 Varnish is a low-priced varnish for printing and printing of gold and silver cardboard products. If operators add a solvent or oil with a boiling point of 200-350°C, they can be applied on offset or screen printing. If the operator adds a solvent having a boiling point of 100-200° C., a glazing may be performed on the flexible letterpress; if the operator adds a solvent having a boiling point of 50-150° C., a glazing process may be performed on a gravure printer. The use of hand-coating or glazing is even easier. 

WS-3-4 Varnish is a thermosetting resin made of natural rosin resin. This varnish is widely used in daily plastic products to make up for the lack of smoothness in plastic injection molding or extrusion casting. It also changes The resistance to acids, alkalis, alcohols, and heat resistance of plastic products has increased the range of use of plastic products, and has also increased the added value of plastic products. 

WS-3-5 varnish is synthesized with three kinds of environment-friendly resins. The product is widely used in aluminum-plated plastic film, such as candy, food, medicine, chemical building materials and other commodity packaging. Since the varnish can be used after the color paddle or after the dye, it is generally used as a higher-grade printing ink and transparent ink. The packaging and printing manufacturer can use the ink for self-use without having to invest in the ink, or can be used with the device. Reducing the working capital of printed materials, and greatly reducing the cost of ink costs and the amount of inventory consumed in the inks that they have formulated. 

WS-3-6 Varnish A new product targeted at the packaging and printing of metallic foils (such as pure aluminum foil) and does not contain any carcinogenic raw materials. It is divided into low-priced WS-6-1 and medium-priced WS-6-2 and high-temperature, acid, alkali, and alcohol-resistant WS-6-3 Varnish. When the package printer operates, it only needs the usual 30. Hot air or infrared rays at -45°C can cure the film to a light-cured state and will not pull the gloss and ink off the tape.
