According to the different raw materials and equipment, the coating process can be divided into two kinds of coating process and pre-coating process. That is to say, the film used in the coating process is now coated, and the adhesive used is generally solvent-based and emulsion type, prepared according to need. However, the film used in the pre-coating process is pre-coated, and the adhesive used...
There are many factors affecting the quality of the film, in addition to paper, ink layer, film, adhesive and so on In addition to the objective factors, it is also affected by subjective factors such as temperature, pressure, speed, and glue amount. If these factors are not handled well, various laminating quality problems will occur. There are snowflakes on the product 1.The amount of glue is to...
Water-based adhesives for printing are very common, which mainly include water-based pasting adhesive, laminating adhesive, water-based sealing adhesive and so on. Water-based laminating adhesive Water-based film adhesive has been widely used in recent years for its high brightness, low cost, easy operation and water-based environmental protection. Water-based film adhesive is mainly divided into ...

Acrylic paint is a fast drying paint made from pigments suspended in acrylic polymer emulsions and plasticizers, silicone oils, defoamizers, stabilizers, metal soaps. Acrylic paint is water-soluble, but becomes resistant to water when dried.Depending on the amount of paint diluted with water, or modified with acrylic gels, media, or pastes, the final acrylic paint can resemble watercolor, gouache,...
In the production process of water-based polyurethane to add a certain type of additives, it is necessary to pay attention to its role in the various stages of storage, construction, application, and consider and evaluate its role and impact in the next section. For example, when the water-based polyurethane paint is operated with wetting and dispersing agents, it plays a certain role in storage a...
The main difference is that the nature is different, the production process is different, and the characteristics are different, as follows: First, the nature is different 1.Flexo printing Flexo printing is a direct printing method known as flexo printing because of the use of elastic, raised image plates. 2.Gravure printing Gravure refers to gravure printing, first the printing plate on the exces...
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...

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...
In the use of pesticides, only a few cases are the direct use of the original drug, and most of the cases are mixed with other additives and solvents to improve its use value and reduce the cost of use. Surfactant is a kind of additives that can give greater play to the value of pesticides and reduce the cost of pesticides. It plays the role of emulsification, foaming/defoaming, dispersi...
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 hardness and softness of the water-based acrylic resin can be adjusted according to specific needs, but it is usually biased towards the harder side. First, the characteristics and application of water-based acrylic resin Water-based acrylic resin is an environmentally friendly water-based resin, with non-toxic, easy to clean, dry fast and other characteristics, widely used in furniture, packa...
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 ...
①The residual ink is converted into gray black ink According to the principle of color science, the complementary color of the ink mixed together, its hue will become gray black (red + green, yellow + blue-purple). Therefore, we can use this principle to deploy the complementary ink into gray-black ink by deploying the special color ink, and add it to the black ink in a certain proportion to use i...
In the process of UV flexographic printing, the viscosity of the ink is one of the key factors that affect the printing quality and effect. Choosing the right viscosity UV flexographic ink is crucial to ensure printing quality and efficiency. When adjusting viscosity, it is usually necessary to consider many factors such as printing equipment, printing materials, image details and the expected pri...
First, water-based lotion Aqueous emulsion is a colloidal dispersion system with water as the continuous phase and oil or other non-aqueous substances as the dispersing phase. It is a stable dispersion system formed by tiny oil droplets coated with surfactants. Water-based emulsion has many significant advantages, such as its low viscosity, easy to brush, easy to clean, non-toxic and harmless. The...
