When using acrylic pressure-sensitive adhesive

When using acrylic pressure-sensitive adhesive, there are several points to consider:

1. Surface preparation: Ensure that the bonding surface is clean, smooth, and free from oil or dirt to achieve optimal adhesion. The surface can be cleaned using a cleaner or solvent and thoroughly dried.
2. Apply appropriate pressure: To achieve the best bonding results, apply moderate pressure during bonding. Moderate pressure helps ensure good contact between the adhesive and the surface, improving adhesion strength.
3. Avoid excessive stretching: Excessive stretching of acrylic pressure-sensitive adhesive can lead to adhesive failure. Therefore, it is important to avoid applying excessive tension to the adhesive, especially when applying it to elastic or stretchable surfaces.
4. Avoid prolonged exposure to high temperatures: Acrylic pressure-sensitive adhesive generally exhibits good adhesion performance at lower temperatures. However, prolonged exposure to high temperatures can cause the adhesive to soften or flow, affecting its adhesion performance. Therefore, it is important to avoid excessive exposure to high temperatures.
5. Consider humidity effects: Humidity can affect the adhesion performance of acrylic pressure-sensitive adhesives. In high-humidity environments, the adhesive may absorb moisture and result in decreased adhesion. When using the adhesive in high humidity conditions, it is advisable to choose a pressure-sensitive adhesive with good wet tack properties.
6. Storage conditions: When not in use, store acrylic pressure-sensitive adhesive in a dry, cool environment, away from direct sunlight and high temperatures. Storage duration should be based on the adhesive’s characteristics and the recommendations provided by the supplier.

Please note that the above points are general considerations, and specific usage should be determined based on the particular product and application. It is recommended to read and follow the product instructions and safety guidelines provided by the supplier before using acrylic pressure-sensitive adhesive.
