How to judge the quality of waterborne pressure sensitive adhesive? Pressure-sensitive adhesive quality of good or bad, generally from the drying speed, viscosity, adhesive strength, solid content and PH value and other aspects to measure. 1, pressure-sensitive adhesive drying speed When buying pressure-sensitive adhesive, it is necessary to measure whether the drying speed matches the bondin...
Water-based pressure sensitive adhesive Typical varieties are: transparent sealing tape, electrical insulation tape, masking tape, surface protection tape, double-sided tape, metal foil tape, pipe anti-corrosion tape, logo tape (printing tape), silicone heat- Conductive tape, shock absorptive tape, medical tape, transfer tape, adhesive labels, stationery adhesive films, advertising adhesive f...
In addition to China, the United States, Europe, Japan are the main origin of water-based pressure-sensitive adhesive. Although the world's water-based pressure-sensitive adhesive production cannot be counted,probably the trend can be seen. In the water-based pressure-sensitive adhesive products,transparent sealing tape, stickers label dominant. Production of Pressure-sensitive is low,return ...
The method to determine whether the quality of the seal printing tape is poor: Ordinary sealing tape glue is acrylic glue, also known as pressure-sensitive adhesive, the main component is tincture. Tincture is a kind of macromolecular active substance. The activity will be affected by the level of temperature. Tincture content of glue will directly affect the use of tape. Some individuals thi...
Characteristics of water-based pressure-sensitive adhesive: 1. Diluted with deionized water 2. At room temperature (25 ~ 30 ℃), the glue sizing 24 hours after the bonding force to reach the maximum, can be tested. At low temperatures, the glue drying time is longer, should be based on the actual situation after the test time or sizing as much as possible after the use of heating b...
Chemical properties and performance of water-based pressure-sensitive adhesive mainly reflect in the following nine aspects: 1. Adhesive properties 2. Infiltration performance 3. Anti - peel performance 4. Early sticky and sticky performance 5. Creep shear resistance 6. Temperature resistance 7. Flame retardant 8. Anti-aging, anti-oxidation 9. ...
1. Water-based polyurethane pressure-sensitive adhesive for its environmentally friendly non-polluting characteristics, the future will become the ultimate direction of development of pressure-sensitive adhesive; cost slightly higher than the acrylic, generally used for relatively high-end industries. 2. Solvent-based pressure-sensitive adhesive as a result of a v...
The Selection of good quality water-based adhesive not only help to improve the production efficiency, but also to protect the appearance of the product quality. Such as widely used in the field of self-adhesive water-based pressure-sensitive adhesive, such as water-based pressure-sensitive adhesive which is widely used in the field of stickers. This adhesive has many advantages, it is particularl...
Some of the traditional glue in the adhesion of a great advantage is good adhesion, and the efficiency is very low, the most important thing is relatively low cost, most are someorganic materials. Relatively speaking,the biggest advantage of water-based adhesive is green, the traditional glue is inorganic materials, so it is not very environmentally friendly, pollution is relatively large, water-b...
Plastics are classified into two types: thermosetting and thermoplastic.Among them, thermosetting plastics have high cross-linking density, good solvent resistance and heat resistance, relatively high surface polarity, and wide range of coatings available.For example, unsaturated polyester is called polyester fiberglass. The texture is hard and polar, and there are many coatings that can be used. ...
Current problems with waterborne polyurethane adhesives: (1) Low solid content: At present, the solid content of water-based polyurethane (WPU) can reach 45%. Fewer systems lead to higher drying and transportation costs. Increasing the solid content leads to an increase in the viscosity of the system, which makes emulsification and dispersion difficult. Reduced emulsion stability. (2) Slow drying ...
Composition of water bases adhesive 1.adhesive: also known as adhesive agent, after the surface treatment of two or more adhesive materials firmly connected together, and has a certain mechanical strength of chemical properties, such as epoxy resin phosphate copper oxide white latex. 2.Solid material (base material): determines the main physical, chemical and mechanical properties of rubber joints...
1.Principles of adhesive selection Consider the type, nature and hardness of the bonding material Consider the shape, structure and process conditions of the bonding material Consider the load and form (tensile force, shear force, peel force, etc.) borne by the bonding part; consider the special requirements of materials such as high temperature and low temperature resistance. 2.Properties of bond...
Automotive interior adhesive is a anionic waterborne polyurethane emulsion developed and produced by ourselves, which belongs to environmental protection waterborne polyurethane adhesive. Appearance Dark grey liquid Solid content(% ) 50±1 PH 6-9 softening point(℃) 45-55℃ Proportion(g/cm3) 1.06±0.02 viscosity(mPa.s) 1000-2000(Viscosity can be adjusted) Application Area Automobile interior adhesive ...
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...
