Laminated oil magnetic cards, Identification Card and other cards used in water-based adhesive. The card is both a document and a form or carrier of the document's existence, although it has entered the 5G era,Many things exist in electronic form, such as electronic balance cards, electronic driver's licenses, electronic health care cards, etc.But the physical card such as id card bank card is als...
When waterborne polyurethane is used as adhesive, it must be mixed generally. Based on waterborne polyurethane, crosslinking agent, thickening agent, filler, plasticizer, pigment and other additives can be added. Other types of waterborne resin and water can be added.In order to obtain higher resistance to water Heat resistance and bonding strength, at present a lot of waterborne polyurethane syst...
The most important application indexes of water-based adhesives in the packaging and printing industry mainly include four aspects: bonding strength, high/low temperature resistance, moisture resistance and viscosity holding.In practical application, defects such as weak adhesion and brittle degumming film are basically caused by the above four application indicators are not up to standard.In prac...
Water-based adhesives are environmentally friendly adhesives made of natural or synthetic macromolecule as adhesives and water as solvent or dispersant instead of toxic organic solvents that pollute the environment.Existing water-based adhesives are not 100% solvent-free and may contain limited vocs as additives for their aqueous media in order to control viscosity or fluidity.Advantages are mainl...
Adhesives with water (inorganic solvent) as the solvent/carrier are called water-based glues, solute (glue) can be dissolved in water/or dispersed in water,Water-based glue can be miscible and dispersed in water, diluent is water. Adhesives with organic solvents as solvents/carriers are called oil-based adhesives (solvent-based adhesives). Oil-based adhesives are not soluble in water and cannot be...
◆ The procedure of bonding process:◆ The adhesive surface should be evenly coated to ensure infiltration, as far as possible to avoid bubbles, due to the porosity of the adhesive strength greatly reduced, resulting in degumming.Attention should be paid to the alignment of the position, not staggered, can be pressurized, air exclusion, make it close contact. Time is three important parameters of cu...
The chemical composition of glue, the polymer in the water environment glue (vinyl acetate in white glue is a kind of petroleum derivatives) are round particles, the radius of the general particle is between 0.5~5μm.The bonding of objects is achieved by the tension between the polymers in the glue.In the glue, water is the carrier of the polymer, and the water carries the polymer slowly into ...
Finally, ordinary glue products, ordinary glue products have a certain elasticity and softness, and have a good tensile length but tensile strength and strength is not very large, adhesion welcome you to consult, this is our email sales@sinogracechem.com
Composition of pressure sensitive tape 1.Pressure sensitive adhesive, 2.substrate 3.Primer 4.Back treatment agent 5.Isolation paper The main components of the pressure sensitive adhesive and resin, including rubber such as polyacrylic acid ester or polyvinyl ether, homogeneous base material requirements, small scale and good to solvent invasive, including, (1) fabric such as cotton, glass cloth or...
Surface treatment of metal materials 1)metal material surface degreasing: organic solvent degreasing alkali degreasing electric degreasing ultrasonic degreasing 2)metal material surface derusting 3)Activation treatment of metal surface 4)Metal surface sandblasting treatment: increase the surface roughness Surface treatment of non-metallic materials 1)Mechanical treatment: sandpaper grinding, etc 2...
First, pour the glue on the flat glass to observe its rheology, and wiggle it to observe its rheology,If the flow of glue is too fast, it means that the glue is too thin and poor, and too thick is not conducive to bonding. Secondly, with a hand dip to observe its viscosity if you can slowly draw, a little sticky hand is better. Then, pour it on a small piece of glass to observe its film forming ti...
The bonding effect can be achieved by applying pressure for a short time (non-aqueous solvent heating) It overcomes the solvent volatilization and drying time needed during the operation of structural adhesive, and can improve the working environment After stripping, it can be corrected without contamination and can be reused for many times Easy to operate, can greatly improve the production effic...
1.Permanent and removable options In terms of the performance of adhesives, they can be divided into two categories: permanent adhesives and removable adhesives.(Permanent is generally used in electronic machinery, such as electronic label, typical: mobile phone battery label, removable is generally used in food, personal care, such as: wet wipes label, fruit label, clothing label, etc.) 2.The sur...
Water-based adhesive is a one-component pressure sensitive adhesive of self-crosslinking acrylic ester at room temperature. It has adhesion to wood, PVC, metal, glass board and so on. It is suitable for wood skin, OPP tape, double-sided tape, aluminum foil tape and self-adhesive trademark paper. performance index Composition: acrylic polymer Solid composition: 55% 2 Viscosity: 6000 CPS/25 Crosslin...
Polyurethane sealant is widely used in civil construction, transportation and other industries: Applications in construction - filling and sealing of doors and Windows, glass, etc.; Applications in civil engineering - caulking sealing of expressways, Bridges and airstrips; Automotive applications - Assembly and sealing of Windows (mainly windshield). Polyurethane sealant has many excellent charact...
In the process of coating manufacturing, it is necessary to belong to the hydrophilic polar material Yan, fillers dispersed to belong to the hydrophobic non-polar material organic base material.In order to increase the affinity between inorganic matter and organic polymer, it is generally necessary to use coupling agent or other surfactants to treat the surface of inorganic matter, so that it chan...
