1. Coatings field: Waterborne polyurethane is widely used in waterborne printing inks, wood coatings, metal coatings, automotive coatings, architectural coatings and other fields because of its small curing shrinkage rate, good acid and alkali resistance, wear resistance, weather resistance and chemical stability. 2. Adhesive field: Waterborne polyurethane adhesive has shear vi...
Protective film resin Automobile coating resin High resilience waterborne polyurethane resin 1.Typical properties Appearance: Milky white liquid Protective film resin Automobile coating resin Ph: 7.0-9.0 Automobile coating resin Solid content: 40±1% Charge: Anionic High resilience waterborne polyurethane resin Viscosity (25℃): 300-800cP Elongation (%): >200...
Aqueous matte resin matte aliphatic aqueous polyurethane dispersion is a high performance solvent-free anionic aliphatic matte aqueous polyurethane, dull, soft to touch, with excellent hydrolysis resistance, heat resistance and bending resistance. Product performance Appearance Milky liquid Application With excellent flexibility and adhesion, it can be used alone or mixed with other em...
"If there are small bubbles in the complex, opaque and foggy, it will not only affect the appearance quality, but also affect the peeling strength of the complex, reducing it, which is a very bad phenomenon." 1.The surface tension of the base film is too small, the infiltration is poor, the glue is not uniform, and the space without glue is empty and bubbles are generated. The solution is to use a...
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...
Leather surface treatment agent Matte resin is a surface treatment agent, mainly used to add a matte effect to the leather surface. The principle is to form a layer of tiny particles on the surface of the leather material, and the refracted light is dispersed, making the surface appear matte. Automotive interior leather market demand analysis As a high-grade and beautiful material, leather has a w...
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-...
Rubber mold, silicone mold, shoe mold, latex pillow mattress mold, anti-stick easy mold Teflon spray, good model flon coating, non-stick mold surface treatment process The role of mold coating Molds are common tools in the manufacturing industry and are used to make a variety of products. In order to capture the service life and production efficiency of the mold, people often coat the surface of t...
The most important difference between non-stick cookware and ordinary cookware is that the surface is coated with a layer of non-stick paint, and the Teflon non-stick cookware commonly used on the market is to coat the main raw material of fluorinated resin such as polytetrafluoroethylene coating on the metal surface such as aluminum, copper or iron, and through sintering. Properties of NI-PTFE co...
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 ...
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...
