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...
Together to understand the characteristics of water-based acrylic emulsion! 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 th...
Preparation method of waterborne acrylic emulsion 1.The preparation of water-based acrylic emulsion: the raw materials including acrylic hard monomer, acrylic soft monomer and acrylic functional monomer all acrylic monomer, emulsifier, water added to the pre-emulsifying kettle, emulsifying 30 ~ 40min.A non-stratified emulsion is obtained. Then the remaining water, remaining emulsifier and buffer a...
Acrylic resin is made of acrylic ester and methacrylate and other alene monomers copolymerization resin, through the selection of different resin structure, different formula, production process and solvent composition, can be synthesized different types, different performance and different application of acrylic resin, Acrylic resin can be divided into thermoplastic acrylic resin and thermosettin...
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...
"Non-stick pan" is a very common pot in the kitchen, because in the process of using less oil consumption, less smoke, but also not easy to paste the problem, so it is welcomed by many people. In recent years, however, there have been more and more controversies about non-stick pans: Some people think that non-stick coating will produce toxic substances, can not be used for a long time; Some peopl...
1. the reason why non-stick pot is not stick, all rely on the coating material on the surface of the pot. These coating materials have good lubricity, small friction coefficient, small surface tension, food is not easy to stick to the pot.Two types of coating materials are commonly used for nonstick pans: fluoropolymers, such as teflon, and silicone polymers. Non-stick wok use PFOA-free high quali...
ater Based Polyurethane Peelable Protective Coating PU-207 is a protective resin made of waterborne polyurethane base material with advanced technology. The water-based peeling paint made from this is bright in color, fine and uniform in particle size, coating on the surface of automobiles, furniture, electrical appliances and other objects as a protective coating, has good protecti...
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...
Water - based ink is also known as water - based (oil) ink, referred to as ink.Water-based ink is made of water-soluble or water-dispersed polymer resin, colorant, surfactant and other related additives through chemical process and physical processing. Water - based ink containing a small amount of alcohol water as solvent, ink stability.Therefore, it is especially suitable for food, medicine and ...
Water-based viscosifying emulsion plays a very important role in water-based acrylic pressure sensitive adhesive, which can improve the bonding strength and initial adhesion of pressure sensitive adhesive on high and low energy surfaces, so as to achieve the best balance point, and can improve the application range and grade of pressure sensitive products. Today, we will take you to understan...
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 ...
First: Teflon coating introduction Industrial Teflon coating is suitable for plastic rubber mold, ball mold, glove mold, latex mold, roller, conveyor belt, mechanical parts and other surface treatment, containing "FEP" and "PTFE" polytetrafluoroethylene ingredients with high-performance resin, divided into the bottom coating and surface coating a total of two layers, has the best anti-corrosion, h...
1.Water as a dispersion medium, do not use organic solvents, non-toxic or flammable danger, is environmentally friendly products; 2.Acrylic monomers have many types, containing ester groups, carboxyl groups, hydroxyl groups and other functional groups have strong polarity, it is easy to emulsion copolymerization with other monomers such as vinyl acetate, styrene, vinyl chloride, etc., to make emul...
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...
