Disadvantages of UV adhesive

Although UV self-adhesive has many advantages, there are also some disadvantages, the following are some factors that may affect its use:

Surface tension requirements: UV self-adhesive has certain requirements for the surface tension of the bonded material, if the surface tension is insufficient, it may lead to weak adhesion. Therefore, before using UV self-adhesive, it is necessary to perform surface treatment on the bonded material, such as polishing, wiping, etc., to improve its surface tension.

Not suitable for some materials: UV self-adhesive may not be suitable for all materials, especially for some materials with low surface energy, such as polyethylene, polypropylene, etc., the bonding effect may not be ideal. In addition, for some materials that are not resistant to ultraviolet radiation, there may also be problems such as poor adhesion or discoloration.

Curing speed: The curing speed of UV self-adhesive is faster, but too fast curing speed may make the glue penetrate insufficient, resulting in weak adhesion. Therefore, when using UV self-adhesive, it is necessary to adjust its curing speed according to the actual situation.

Operation difficulty: The operation of UV self-adhesive needs to be carried out under ultraviolet irradiation, for some difficult parts, such as gaps, corners, etc., the operation is more difficult. In addition, if the operation is not proper, it may also lead to poor bonding effect.

Odor and irritation: UV adhesive will produce a certain odor and irritating gas during the curing process, and it is necessary to pay attention to ventilation and protection measures.

In general, although UV self-adhesive has many advantages, it is necessary to pay attention to its shortcomings and limitations when using, and choose the appropriate glue and operation method according to the actual situation.
