Water based polyurethane is a kind of block copolymer containing soft segment and hard segment. The soft segment is composed of oligomer polyols, and the hard segment is composed of polyisocyanate and chain extender. It has excellent wear resistance, oil resistance, low temperature resistance, aging resistance and chemical resistance.At present, the water based polyurethane emulsion on the market ...
Polyurethane (PU) is a kind of organic polymeric compounds containing repeated carbamate group (NHCOO) in the main chain.Polyurethane polymer materials have the advantages of wear resistance, high temperature resistance, good adhesion, easy processing, low price, but some polyurethane water resistance, heat resistance is poor, need to be modified by specific methods, in order to achieve the purpos...
Water-based coating is an effective means to process the surface of printed matter, to improve the gloss and strength of the surface of printed matter, enhance the aesthetic effect, temperature resistance, water resistance, wear resistance, improve the grade of printed matter and commodity value. Therefore, to measure the quality of the coating, it is also necessary to examine the brightness, stre...
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...
Adhesive label is a representative pressure sensitive adhesive product which coexists with adhesive tape for packaging. Its wide range of uses, such as: food, cosmetics, drugs and other use of senior beautiful label; Quality marking labels for fiber products, electronic machines, daily necessities, etc.; A price tag used in a supermarket or grocery store; Computer tags for schools, hospitals and o...
After the composite product has been cured at a certain temperature and time, the interlayer peeling composite film adhesive layer still has a certain viscosity, that is, after the composite film peeling, the two-layer film will be re-glued together by hand, and the severe drying of the composite film adhesive layer will directly affect the peeling strength of the composite film, while the slight ...
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...
PET protective film material is transparent colorless, the surface after hardening treatment, the general PET protective film material according to the origin of different, the surface hardening value between 3H-4H, the better the surface hardening, the stronger the wear resistance. Light transmittance is also the main property of PET protective film materials, the general light transmittance is m...
