Protective film glue transfer, there are a variety of factors, I believe that in the work, many teachers will also encounter a similar situation.The phenomenon of the so-called glue transfer is uneven coating or in the process of transportation, the glue shift remains on the surface of the profile, commonly known as glue transfer. Protective film glue transfer can be divided into the followin...
During December 10, 2022, customers from Russia have come to visit our company. Foreign trade manager and relevant personnel warmly welcome our customers, and introduced our product which they are interested in detailedly. Water based glue
Classification and characteristics of screen-printable pressure sensitive adhesives I.Characteristics and performance requirements of screen printing process Screen printing is through a certain pressure to make the printing base material through the holes of the plate to the substrate, the formation of an image or text. In order to achieve good printing adaptability, the physical properties of sc...
Classification and characteristics of screen-printable pressure sensitive adhesives Ⅱ Classification of screen-printable pressure sensitive adhesives Because of the simple screen printing equipment, convenient operation, simple printing, plate making and low cost, for the application of coating pressure sensitive adhesive, also often consider the use of screen printing process to coating.The ...
Screen printing UV pressure sensitive adhesive and screen printing water-based pressure sensitive adhesive, has the following different characteristics: because UV curable pressure sensitive adhesive does not contain water or organic solvent, so it can be cured without heating drying channel, and water-based pressure sensitive adhesive to water as diluent, need a lot of heat to volatilizing water;...
water-base adhesive With the development of society, the quality of glue has been pushed to a high point, which also led to the development of water-based glue. At present, the environmental protection industry is in a stage of rapid development. People pay more and more attention to health and environmental protection issues. The chemical glue industry is also in a stage of rapid change, and wate...
Waterborne polyurethane: A new type of polyurethane system using water instead of organic solvent as dispersion medium, also known as water dispersed polyurethane, water polyurethane or water based polyurethane. Oily polyurethane: polyurethane system with organic solvent as dispersion medium, polyurethane system with thermoplastic linear structure. Distinguish by appearance Waterborne polyurethane...
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 ...
Water-based adhesive with high polymer, water-soluble resin as the main raw materials, water as the solvent, less odor, environmental protection. With the continuous improvement of people's environmental awareness, water-based adhesives have become the mainstream of the market in recent years. Characteristics of water-based adhesive 1.Applicable to the substrate any kind of adhesive is not om...
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...
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 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...
Labels, as they are called in the printing industry, are mostly printed materials used to identify the relevant instructions of their products, and most of them come with glue on the back. But there are also some printing without glue, can also be called labels. Glue label is colloquially known as "sticker label". Label base material classification Substrate application surface material paper...
