Anti -deformation power Anti -deformation capacity refers to a certain deformation after the composite product is affected by external forces, and this deformation will produce a certain amount of elasticity, especially the thin film. If the combination of composite is not enough to resist the elasticity of the return, foaming will occur, etc. Happening. There are many processes that produce defor...
Eight, filling The concept of filling is rarely mentioned in the application of laminating glue, but can never be ignored.The surface of the paper inevitably exists in some depression. When compounding, if the depression in the paper cannot be fully filled, it will also cause the weak. (Excellent filling effect) &nb...
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
Existing water-based adhesives are not 100% solvent-free and may contain limited volatile organic compounds as additives to their water-based media in order to control viscosity or fluidity.The advantages are mainly non-toxic, no pollution, no combustion, safe use, easy to achieve clean production technology, etc., disadvantages include slow drying speed, poor water resistance, poor fros...
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 ...
Because the water glue is bonded together by the film forming principle, its compound effect is very stable, and the product can be cut immediately.If the composite quality is bad because of the process or substrate, it can also be seen in the first time off the machine, and it will not be found after mass production.Therefore, the composite packaging products use water-based glue instead of solve...
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...
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...
Self-adhesive refers to paper, film or other special materials as fabric, coated with adhesive on the back, a composite material printed with silicon protective paper as the base paper, the reason for the rapid rise of self-adhesive in recent years, because it is very practical, and very convenient, the cost is not high, the following to tell you about a few small knowledge of self-adhesive printi...
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...
I.Overview: Refilm process is widely used in all kinds of packaging, small to medicine box, artifact box, large to outer packing boxes and various product packaging.The current recoating technology includes precoating, dry recoating and wet recoating.Wet composite uses water-soluble adhesive cold paste process. Dry composite traditional composite film process is to apply solvent-based adhesive dir...
Water-based adhesive with high polymer, water-soluble resin as the main raw materials, water as the solvent, odor is small, environmental protection and non-toxic. With the continuous improvement of people's environmental awareness, water-based adhesives have become the mainstream of the market in recent years. In practical application, some packaging and printing manufacturers do not know enough ...
Choice of water-based adhesive Application index Some packaging and printing enterprises reflect that some water-based adhesives will degummy soon after gluing; Viscosity is not stable, sometimes bond firmly, but sometimes not bond; It works well in hot weather, but it doesn't work in cold weather.In fact, this is due to the lack of understanding of water-based adhesive application indicators. The...
