Polyurethane adhesive is a kind of high-grade adhesive, with excellent flexibility, impact resistance, chemical resistance, wear resistance, and the most important is its low temperature resistance. Because of its series of advantages, polyurethane adhesives are widely used in the following fields. 1. Carpentry industry With the improvement of people's awareness of environmental protection, the wo...
Polyurethane (polyurethanes, abbreviated PU) is a kind of polymer with -NHCOO-repeat structural unit as the main chain. Isocyanate (monomer) is polymerized with a hydroxyl compound.Due to the strong polarity of the carbamate group, insoluble in non-polar groups, with good oil resistance, toughness, wear resistance, aging resistance and adhesion. Materials suitable for a wide temperature range (-50...
1.Excellent adhesion The polymer structure of water-based acrylic emulsion contributes to the flow and wettability of molecular chains on the substrate surface, making the coating and substrate molecules in close contact, to achieve high adhesion. 2.High load-bearing capacity of the makeup filler can significantly reduce the cost Waterborne acrylic emulsion has excellent fillability, the total sol...
Acrylic acid Important organic synthesis raw materials and synthetic resin monomer Acrylic resin is an important organic synthesis raw material and synthetic resin monomer, is a very fast polymerization rate of ethylene monomer.Is the simplest unsaturated carboxylic acid, consisting of a vinyl group and a carboxylic group. Most of them are used to manufacture methyl acrylate, ethyl ester, butyl es...
Application Acrylic emulsion is a kind of emulsion with wide applicability for construction. It can be used as a new chemical material for repairing steel structure concrete of hydraulic construction, port construction, highway, bridge, metallurgical chemical industry (urea chloro gangue) and other industrial civil buildings, such as seepage prevention, corrosion prevention and antifreeze. Cl...
Polyurethane is the short form of polyurethane (PU). It is a block polymer formed by addition polymerization. It is a polymer compound with flexible and elastic polyether or polyester as soft segment and rigid and hard carbamate as hard segment. It contains a considerable number of ammonia ester bonds. Waterborne polyurethane has been successfully applied in the textile printing and dyeing industr...
The addition of wetting dispersant has obvious effect on the foam of some water-based ink.For example, polyacrylic acid wetting dispersants foam more than other types of wetting dispersants.Generally speaking, wetting dispersant foam with low dispersion capacity is also less. If diisobutyl sulfonate is based on disate, there is little foam at its content of 0.1-0.25%. The use of thickeners will ma...
Water based adhesive Water-based adhesive refers to the water-soluble polymer dissolved into appropriate concentration of aqueous solution, or insoluble polymer dispersed into micro-particles (emulsion) in water with the help of surfactant in the general term of adhesives;In simple terms, adhesives made of materials that can be dispersed or dissolved in water are aqueous adhesives and are often re...
Environmental protection pressure has prompted some traditional solvent-based products to gradually withdraw from the market and replace them with water-based, high solid content, powder products, etc.Waterborne polyurethane, as an important member of waterborne products, is facing unprecedented development opportunities with its unique excellent properties.In addition to the leather industry, it ...
Pressure sensitive adhesive (PSA) is a self-adhesive material, only need to apply a small pressure, can form a van der Waals force on the surface of the two objects, and the adhesive is firmly bonded, this pressure sensitive bonding performance is its basic feature, is also different from other adhesives typical characteristics. PSA can be divided into solution type, emulsion type, photocuring typ...
Water-based pressure-sensitive adhesive is a type of adhesive that uses water as a solvent and is pressure-sensitive, that is, it can adhere quickly to the surface when slight pressure is applied. Due to its environmental protection, non-toxic, cost-effective, adjustable viscosity and other advantages, it has gradually become the mainstream product in the pressure sensitive adhesive market. Accord...
Advantages and disadvantages of the same type of defoamer Organic defoamer such as mineral oils, amides, low alcohols, fatty acids, fatty acid esters and phosphate esters has been studied and applied earlier, belonging to the first generation of defoamer, which has the advantages of easy access to raw materials, high environmental performance and low production cost.The disadvantages are low defoa...
1 Fluorescent ink: Fluorescent ink is made of fluorescent material dissolved in the corresponding resin. The particles of fluorescent pigments are generally thicker, the types of bonding materials are more, different bonding materials will produce different fluorescence, in the use of fluorescent ink should ensure that it has sufficient concentration, the ink layer on the printing product is thick...
Let's take a look at the characteristics of water-based acrylic emulsion! 1.Excellent adhesion The polymer structure of the aqueous acrylic emulsion contributes to the flow and wettability of the molecular chains on the surface of the substrate, making the coating and the substrate molecules in close contact to achieve high adhesion. 2.The high bearing capacity of the filler can significantly redu...
Pigment printing The printing method of coating printing is that the non-water-soluble substance particles with color or special effect are adhered to the fiber/fabric surface with a polymer adhesive to form the desired pattern. Paint printing characteristics 1.the process is simple and convenient, wide applicability to fibers; 2.Complete chromatography, bright color; 3.Clear outline and distinct ...
