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...
Factors affecting the curing speed are the main types of paint, coating thickness, curing methods, curing conditions, curing equipment and specific curing procedures. 1.The type of paint Under the same curing conditions, the type of paint is different, the curing speed is very different. Generally speaking, the volatile paint curing fast, oily paint curing is slow. Polymeric paint is very dif...
Classification and quality requirements of BOPP sealing tape (including ordinary sealing tape, printing tape, high-viscosity antifreeze tape):The series of products mainly to polypropylene film, special polypropylene film, acrylic and water-based acrylic plastic as raw materials and has the characteristics of posting smooth. It is suitable for general packaging and fixed and packaging an...
Cold winter can not stop the fiery heart, amiable yadav, traveled across the sea traveled to Anhui sinograce in the Nien water based adhesive business negotiations for the cooperation between the two sides opened the first step to success, I believe we will be more and more cooperation in the further.
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...
1. acrylic water-based paint The use of acrylic emulsion as the main component, the main feature is good adhesion, will not deepen the color of wood, but the wear resistance and chemical resistance is poor, the film hardness is soft, fullness is poor, comprehensive performance in general, film Good construction is easy to produce defects. It is suitable for water-based wood primer, matte finish. 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...
Introduction: Water-based adhesives to water as a dispersion medium adhesive, is a major category of environmentally friendly adhesives. The solvent-based adhesive is a homogeneous system with organic solvents such as benzene and toluene as the dispersion medium. The water-based adhesive is a heterogeneous system with water as the dispersion medium. Classification: Water as a disper...
Sinograce Chemical holds the 2018 employee games at the cultural and sports activities center on July 2, 2018.More than 80 people from six teams took part in the competition. It consists of three events: tug-of-war, table tennis and badminton. In the competition, each team elaborately arranged, strives for success, on the field fully displays each special strength and the ball skill.Off the f...
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...
Waterborne polyurethanes are mostly milky white. The whole process of waterborne polyurethane can be divided into two stages. The first stage is pre-stepwise polymerization, that is, the oligomeric diol, the chain extender, the water-based monomer and the diisocyanate are progressively polymerized through the solution to produce an aqueous polyurethane prepolymer having a molecular mass of the ord...
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...
Analysis on the application of waterborne polyurethane (WPU) in coatings Waterborne polyurethane is used in water based wood coatings, which is expected to obtain excellent film hardness, heat resistance and dielectric properties, and good film-forming properties. The higher the degree of microphase separation of aqueous polyurethane,the greater the difference of softening temperature, the better ...
Colorful paint is mainly used in imitation stone effect, so also known as liquid stone and the horizon exterior paint.is composed of incompatible two-phase components, one of the dispersion medium for the continuous phase, the other phase for the dispersed phase. Painting, through a one-time spray, you can get luxury, beautiful, colorful patterns. The pattern formed by the one-time spraying is com...
Water-in-water multi-color paint spray guns to use most of the spray, for the operation, but also because of the improper use of the gun caused by uneven distribution of the coating,the following together to see how to solve it. The smaller the gun distance, the greater the pressure of the spray, the greater the impact of the product by the pressure of the water, water-in-watercolorful paint coati...
