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...
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 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 ...
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...
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...
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...
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...
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...
The grinding fineness of paint is one of the important qualities of color paint, which has a great impact on film forming quality, film gloss, durability, storage stability of paint, etc., and is one of the routine testing items of paint production. The fineness of the paint refers to the size of the particle size or the uniformity of the dispersion of the pigment or the bulk pigment, and the unqu...
The main reason for water-based ink drying 1.Water-based ink: water-based carton ink, non-woven ink, paper towels, paper cups and paper bags and other packaging printing; 2.Water-based polishing oil series: water-based polishing oil, polishing oil, high gloss, wear-resistant, matte, waterproof, antifreeze and other environmental protection water-based products. Water-based ink drying is mainly cau...
