One,Overview Paper-plastic composite can make the surface of paper printed matter more bright, smooth and color more bright and full of three-dimensional sense, but also play a role in moisture, anti-fouling, anti-counterfeiting, folding resistance, wear resistance and so on.It has been widely used and rapidly developed in printing and packaging industry at home and abroad. The market demand for p...
Non-stick coating refers to the coating formed after coating with low surface energy, easy to clean and other characteristics of the coating, which is widely used in all kinds of food contact, hardware products, mechanical parts, chemical equipment, electrical equipment. Non-stick pans are also the most widely recognized non-stick paint application scenarios. 1. non-stick coating has fluorine resi...
First, environmental performance VOC content Needless to say, water-based wood paint is perfect in this respect, water-based wood paint is based on water as a solvent with ultra-low VOC content, and will not produce pungent odor during construction. Nitrocellulose paint and polyester paint add organic solvents, and their products contain benzene, toluene, xylene and its derivatives, whic...
Organic pigment is the most basic material to provide color to the ink, but as the ink attached to the surface of the substrate, the color shown to the consumer often produces more or less deviations from the color of the pigment itself. The reason is that in the ink, the pigment particles do not exist alone, but are dispersed in the connecting material medium. Microcosmic, the best wetting disper...
Anti-viscosity is an important physical property index of printing ink.Gravure printing is a kind of printing method with high ink supply, good reproducibility and fast printing speed. Most of the inks used are solvent-based volatile drying inks.After the ink is transferred to the substrate through the printing plate, it passes through the drying channel, and the organic solvent is quickly volatil...
The resins that can be used for water-based gravure inks are acrylic resin, polyurethane resin, alkyd resin, etc. Each resin has different characteristics and application occasions, and needs to be selected according to the actual situation. First, water-based gravure ink overview Water-based gravure ink is an environmentally friendly ink, compared with traditional ink, its volatility is small, no...
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...
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-...
PTFE coatings (polytetrafluoroethylene) are non-stick, fluoropolymer containing high temperature coatings, they have a single coating system or a double coating system of primer and top coat, and have a variety of properties. The Teflon spray process is an important surface treatment that gives objects outstanding properties. With the right preparation, spraying procedures and techniques, Teflon s...
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...
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...
Teflon is the abbreviation of polytetrafluoroethylene, this material has the characteristics of acid and alkali resistance, resistance to various organic solvents, almost insoluble in all solvents, so it has the title of "non-stick coating". With the development of thermal spraying technology, Teflon coatings can be applied to stainless steel, copper, aluminum, magnesium and various alloy metal ma...
Main properties of Teflon coating Teflon high-performance special coating is a fluorine coating based on polytetrafluoroethylene matrix resin, the English name is Teflon, because of the pronunciation, it is usually called Teflon, Teflon, Teflon, Teflon, etc. (all are translations of Teflon). Teflon coatings are a unique, high-performance coating that combines heat resistance, chemical inertia, exc...
