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...
Common problems with water-based paint: the coating contains bubbles and degassing Phenomenon: During the production of waterborne coating, it is found that the coating contains bubbles after thickening.The bubble volume is big bubble, the volume is small bubble, This kind of phenomenon often happens in paint of equal thickness thick pulp of elastic drawing. Bubble may cause pinhole or prickly hea...
Waterborne two-component paint seeds and loss of light - ask water-based paint experts Question: Hello! I have two problems with the double-surface water-based topcoat. One is that when the film is thick, it is easy to produce rash [related to defoaming agent or related to water and curing agent to produce CO2?]. One is a double component. After mixing for 2 hours, it will lose light. What is the ...
Formation of shrinkage cavity problems in waterborne coatings The surface defects of the coating film are mainly depressions, pinholes, and the edges or thick edges of the corners. There are two kinds of cases on the surface of the coating film, one is a circular depression, and a hexagonal polygonal depression. The depression on the surface of the coating film is caused by the surface tension gra...
Factors Affecting Shrinkage of Waterborne Coating Films In practice, the main causes of shrinkage are as follows: 1. The substrate is contaminated by oil or impurities 2. Apply a paint to the old paint or finish without sanding 3. The interval between constructions of the two paints is too long 4. Too much defoamer in the paint The following focuses on two factors: defoamer and impurity contaminat...
Abstract: Reducing the shrinkage of water-based paint film is focused on prevention,designing a rational paint formulation,controlling the paint manufacturing process, and strictly controlling the detection of paint materials, which can reduce the chance of shrinkage. Shrinkage holes have been caused, and it is usually difficult to completely solve them. It is necessary to control the degree of sh...
Feature Traditional surfactants (mainly anionic or nonionic) Putty and low-grade system Efficient Reduce static surface tension Good effect on contaminated substrates Easy to cause surface problems Not easy to control High price PSAMS Wide adaptability Common application Minimize possible defects Minimize possible defects Low water sensitivity Low foaming Good dynamic effect expensive visit us sin...
The types and functions of surface control agents include: 1.Improve flow and leveling 2.Reduce friction coefficient and increase slip 3.Enhanced scratch resistance 4.Anti-blocking 5.Enhance the arrangement of matte powder, etc. 6.Special feel, such as softness, etc. 7.Others such as improving the water resistance and stain resistance of the coating film On the one hand, they balance the surface t...
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. ...
