(2) if the client app...
At present, two-component waterborne polyurethane has been widely used in leather, textile dyeing AIDS, adhesives, foam materials, coatings and other fields. With the continuous development of two-component waterborne polyurethane scientific research, it is gradually replacing solvent polyurethane as the medium to occupy the dominant position in the market. One: leather China's leather resources, ...
Anhui Sinograce Chemical Co., Ltd Polyurethane condoms, known as condoms, are made of polyurethane condoms, similar to latex condoms. Polyurethane was applied to condom production in Japan, until the emergence of China's Nakagawa 001, which broke Japan's monopoly on the production field. Because the common latex condoms on the market are thicker and polyurethane has good ...
Plasticizer is widely used in industrial production of polymer materials auxiliaries, also known as plasticizers. All substances added to polymer materials that increase polymer plasticity are called plasticizers. The use of plasticizer can improve the properties of polymer materials, reduce production costs and improve production efficiency. is a class of important chem...
Water-based wood lacquer can be used to apply. The characteristics of the brush method is simple, easy to master, fast coating speed, and can eliminate the brush method commonly seen bubbles and brush marks and other shortcomings. This is because the paint left on the surface of the wood is very thin and the pressure of the brush is high, which makes the air in the wood grain and micro hole easy t...
Water based wood lacquer is mainly made of waterborne acrylic acid and polyurethane and refined by strict production process standards. It is suitable for the protection of indoor wood and wood products, and can play the role of decoration, protection and service life extension.Waterborne wood lacquer uses water as diluent, does not contain benzene and other harmful substances, non-toxic...
What are the uses of waterborne acrylic emulsions? Waterborne acrylic emulsion is used as finishing agent for silk fabrics and leather Water based acrylic emulsion is used as finishing agent and treating agent for photographic printing paper Waterborne acrylic emulsion has good sealing performance on wood grease and tannic acid, used as transparent sealing primer for wood,...
According to the current development trend of waterborne polyurethane coating, green polyurethane coating technology is mainly divided into two categories: waterborne polyurethane coating and solvent-free polyurethane coating.Among them, solvent-free polyurethane coating mainly contains polyurethane hot melt adhesive coating and light curing polyurethane coating.Waterborne polyurethane (WPU) is a ...
With the development of The Times, people's invention is more and more magical, super hydrophobic coating is one of them, the use of the product can make the surface of the pollutants or dust can be gravity, rain or wind and other external forces automatically removed or degraded.What factors will affect the coating hydrophobicity, let us know about it. 1 hydrophobic principle The wettability of w...
Cotton fabric is loved by everyone because of its good application characteristics such as soft touch, comfortable wear, moisture absorption and air permeability, but it also has defects such as poor elasticity and wrinkling after washing.In order to improve the shape retention of cotton fabric and to make it easy to maintain, it is usually treated with a hands-off finish.Etherified 2D resin finis...
PCL is a fully degradable polymer with good biocompatibility. When introduced into waterborne polyurethane, it can make waterborne polyurethane have shape memory.Shape memory waterborne polyurethane has attracted wide attention for its shape memory function, temperature sensitivity and moisture permeability. PCL3000 PCL4000 was used as the soft segment, and toluene diisocyanate was used as the har...
When waterborne polyurethane is used as adhesive, it must be mixed generally. Based on waterborne polyurethane, crosslinking agent, thickening agent, filler, plasticizer, pigment and other additives can be added. Other types of waterborne resin and water can be added.In order to obtain higher resistance to water Heat resistance and bonding strength, at present a lot of waterborne polyurethane syst...
Waterborne polyurethane adhesive is a kind of high-grade adhesive, with excellent flexibility, impact resistance, chemical resistance and wear resistance, the most important is its low temperature resistance.It has adsorption and chemical bonding effect on many kinds of materials. It can not only bond porous materials, but also bond smooth surface materials. It is widely used. Polyurethane adhesiv...
Water-based plastic composite ink is a product with water as the solvent. From the perspective of printing mode, water-based ink is not suitable for offset printing at present. Its main application fields are flexographic printing gravure printing and screen printing. Printing costs are related to the raw materials selected by ink manufacturers, such as the size of the molecular weight of the resi...
