First, material selection and preparation To make the resin crack effect, you first need to prepare the resin and pigment. Resin selection of high transparency, high hardness, wear resistance products, pigments can choose mineral pigments or metal pigments, you can also add a small amount of color pigments to prepare a rich color. Second, color mixing Mix the paint into the resin one by one and st...
Different processing methods will cause different fault manifestations, the following we mainly analyze the causes of paper thermit sealing delamination phenomenon under the gravure and solvent-free composite processing methods. The YBB paper aluminum-plastic composite film standard does not specify the composite strength index of the paper aluminum layer in the paper aluminum-plastic composite fi...
Water-based ink is referred to as ink, and flexible water-based ink is also known as liquid ink, which is mainly made of water-soluble resins, organic pigments, solvents and related additives by composite grinding processing. Water-based ink is especially suitable for tobacco, wine, food, beverages, medicines, children's toys and other packaging and printing products with strict sanitary condition...

Card film, also known as plastic film, is a plastic film product coated with adhesive and OPP and PET as the substrate, which is widely used in the storage and protect...
The high adhesion base coating improves the adhesion of the inkjet coating on PP paper Prevent ink from penetrating into PP composite paper substrate Fast drying speed to meet the needs of production line Good weather resistance, no yellowing Easy to use, safe and environmentally friendly Anhui sinograce company's PP composite paper digital inkjet coating adhesive base | Inkblot coating base ...
Enhance the adhesion of UV ink and UV varnish on paper products! The tape won't come off Fast drying speed to meet the needs of production line Good affinity with UV varnish and UV ink Excellent strength and toughness Water-based UV base oil for high adhesion paper products Anhui Sinograce Chemical waterborne UV primer for high adhesion paper products is a high-performance waterborne coa...
Insufficient or uneven amount of glue due to insufficient amount of glue produced by the white spot can be observed in the composite machine. In the dry composite process, the coated adhesive must be able to fill the bumps and bumps on the surface of the ink and film to avoid appearance defects such as obvious white spots. When the water-based adhesive dry composite is used to produce lightweight ...
The final state of waterborne polyurethane is a solid film. During the process from emulsion to solid film, accompanied by the evaporation of water and the concentration of water dispersion, the latex particles are close to each other. Before the solid content reaches 74%, the dispersion particles can move in the continuous phase of water. Under the influence of water/air interfacial tension, the ...
Due to the hydrophobic properties of waterborne polyurethane resin, it is difficult to dissolve in water or disperse uniformly, and the high reactivity of isocyanate groups to water, the direct synthesis of waterborne polyurethane faces many challenges. Therefore, to achieve the preparation of waterborne polyurethane, the primary strategy is to cleverly integrate hydrophilic functional groups (suc...
Water based polyurethane emulsion has soft properties, so that it has good adhesion when attached to the surface of the object; At the same time, it can maintain a certain strength and does not crack. It is especially suitable for articles in high temperature, humid and chemically corrosive environment. This substance also has superior wear resistance and film smoothness, so it can form a uniform ...
Waterborne Polyurethane (WPU) is a polyurethane system using water as a solvent or dispersion medium. In recent years, with the increasingly strict environmental regulations and the improvement of people's environmental awareness, waterborne polyurethane, as an environmentally friendly material, has received extensive attention and research. First, the characteristics of waterborne polyuretha...
Paper aluminum-plastic composite film in the actual application of medical packaging powder, granule packaging products compared to the plastic aluminum-plastic packaging commonly used in the market now has the following advantages: (1)The mechanical strength of the paper is high, the rigidity is good, and the ability to maintain the bag after forming is strong, which improves the cleanliness of t...
Aluminum foil can also be printed with water-based ink. As a non-absorbent substrate, aluminum foil poses a major challenge to water-based ink printing. However, some aluminum foil products that require food-grade printing cannot be printed with oil-based inks, so water-based inks have become the best choice. However, due to the poor absorption of aluminum foil to water-based ink, many inexperienc...
There are several main reasons for water-based emulsion breaking: 1.Large temperature changes, water-based emulsion is easy to separate into water phase and oil phase at high temperature, and easy to crystallize at low temperature. 2.The selection of emulsifier is improper, and the type and dosage of emulsifier are different, which has a great impact on the stability of emulsification. The choice ...
Before the textile coating, it is necessary to pretreat the textile surface to ensure the adhesion and quality of the coating. Common surface treatment methods are: cleaning, degreasing, polishing and so on. Cleaning can be done with hot water or solvents, degreasing can be done with alkaline or acid degreasing agents, and polishing is done by mechanical removal of surface hair. The choice of coat...
