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...
PET label primer Cost-effectively improve the printability of PET labels Excellent adhesion with PET label substrate Good affinity with all kinds of ink Good weather resistance, no yellowing Easy to use, safe and environmentally friendly PET label primer is a water-based coating designed to improve the printability of PET label paper with advanced material technology and formulation technology. Du...
The OPP,PET film substrate | is an environmentally friendly coating using advanced material technology, which can significantly enhance the adhesion of EVA on difficult PET substrates and improve the product quality of PE card film. 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...
Waterborne polyurethane (WPU) is a water-based dispersion material, and its unique low viscosity characteristics often bring construction challenges such as flow hanging and penetration. In order to solve these problems and improve its construction performance, self-leveling performance and storage stability, the addition of thickener has become a key step. The thickener not only endows the water-...
First: the treatment of the substrate First, the substrate (aluminum, stainless steel or other metal substrate) is baked at high temperature (360℃×30 minutes ~380℃×10 minutes) to carbonize the grease or degreaser cleaning for the first step of degreasing. Step 2: Roughening the surface Available corundum sand 80#~120#, pressure 0.4~0.6mpa, sandblasting, so that the surface roughness of the substra...
In the face of different needs of different industries, rollers also need to do the corresponding coating treatment, so as to improve or compensate the relevant performance of the roller. So what are the surface coating technologies for rollers? 01 Coating treatment The coating treatment of the drum includes zinc plating, chromium plating, nickel plating, etc. The different coating treatment can i...
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...
Teflon coating is one of the commonly used protective coatings in metal thermal spraying processing technology services, with good non-stick, wear resistance, corrosion resistance, high temperature resistance and other characteristics, can be applied to carbon steel, stainless steel, aluminum, copper, magnesium and various alloys and other metal materials. It can also be applied to non-metall...
1.Ink The three primary color inks have different degrees of color bias, which will affect the color bias of the whole picture to different degrees. However, a small amount of color bias can be corrected from the ink preparation. When printing to grasp the gray balance of the ink used, the same amount of yellow, product, green do not produce neutral gray, they produce lighter, more turbidity with ...
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...
The viscosity of waterborne polyurethane emulsion has different distribution range, and the viscosity of waterborne polyurethane emulsion has different requirements when applied in different fields. In addition to adjusting the viscosity by adding thickening agents, it can also affect the viscosity of waterborne polyurethane emulsion from the molecular structure, including the content of hydrophil...
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...
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...
