Adhesive curing

Hits: 875 img

    Adhesives are generally liquid or paste-like. These adhesives need to be cured before they can play their bonding role. Therefore, the curing process of the adhesive is also very important. If the curing process is not good or you do not know how to cure it, If you need to pay attention to something, it will have a great impact on the bonding of items. No matter how good the adhesive you use is, it may affect the bonding effect.

    The adhesive curing reaction is a process that obtains and improves properties such as bonding strength through chemical reactions (polymerization, cross-linking). Curing is a key process to obtain good bonding properties. Only when it is completely cured can the strength be maximized. Curing is divided into initial curing, basic curing and post-curing.

    1. Initial curing: Under certain temperature conditions, it reaches a certain strength after a period of time. The surface has hardened and is not sticky, but the curing is not over.

    2. Basic curing: After a period of time, most of the reactive groups will participate in the reaction and reach a certain degree of cross-linking.

    3. Post-curing: In order to improve the bonding performance or due to the needs of the process, the basically cured adhesive material is treated. It is generally maintained at a certain temperature for a period of time to supplement the curing and further improve the degree of curing. It can effectively eliminate internal stress and improve bonding strength.

    In order to obtain a well-cured adhesive layer, the curing process must be carried out under appropriate conditions. The curing process of the adhesive has a very important impact on the bonding quality. There are three basic process parameters in curing: temperature, pressure and time. These three parameters have a great influence on the curing of the adhesive.
