How to choose the suitable silk screen glue for oneself?
Many customers know what kind of silk screen adhesive labels they need, but they are struggling with the issue of label adhesive. Adhesive is very important for the adhesion of silk screen adhesive. If they choose the wrong one, light edges may curl and overflow, heavy ones may completely fall off without adhesion, and even damage the item. Therefore, before ordering silk screen adhesive labels, customers must understand their application needs so that they can make targeted choices. The characteristics of adhesive are classified into many categories, and the following can almost meet the selection needs of most customers.
1. Permanent and removable options:
In terms of the performance of adhesives, they can be generally divided into two categories: permanent adhesives and removable adhesives. (Permanence is generally applied to electronic machinery, such as electronic labels, typically for mobile phone battery labels, and removability is generally applied to food, personal care, etc., such as wet tissue labels, fruit labels, labels on clothing, etc.)
2. Surface of the sticker:
Because labels processed with silk screen glue and water-based materials may be affixed to the surfaces of various materials such as glass, metal, cardboard, and plastic. Plastic can be further divided into polyvinyl chloride and high-density polyethylene. Tests have shown that different sticker surfaces have a significant impact on performance. (Use adhesives and materials with the same or similar chemical composition to stick to the object being pasted)

3. Surface structure of label substrate
Simply put, a rough label surface requires adhesive with strong viscosity.
4. Surface shape of label substrate
The surface of the label substrate can be divided into flat and curved surfaces. If the label surface has a certain curvature (such as the surface of a medicine bottle with a diameter less than three centimeters), it may require the surface paper to have good adhesion or adhesive with strong viscosity. It is also necessary to choose materials with better flexibility and tensile strength, such as PVC. The flat surface of the object being labeled is more adaptable to a wider range of labeled materials.
5. Cleaning condition of label surface
Screen printing adhesive material is suitable for label substrates with clean, dry, oil-free, and dust-free surfaces. (When labeling, it is necessary to keep the surface of the object being labeled dry, oil-free, and dust-free in order to achieve good labeling results.)
6. The adverse effects of plasticization on adhesive
Labeling conditions - The viscosity of the silk screen adhesive needs to be applied under cold, hot, humid, or room temperature conditions. Environment of use - whether the silk screen adhesive label is exposed to environments below freezing point, whether it is used outdoors, in high temperatures, humidity, or in light containing ultraviolet rays, and whether it is close to high-temperature car engines.
