High-performance silicone structural adhesive is a kind of high-strength sealing material commonly used in construction, automobile, electronics and other fields. Its main components are siloxane chains and hydrogen bonds. The special structure of these components makes silicone adhesive have good properties such as high temperature resistance, ultraviolet resistance and oxidation resistance. However, in some cases, due to long-term immersion in water, some components of silicone adhesive may change, thus affecting its performance and service life. Among them, the hydroxyl group (OH-), one of the components of silicone adhesive, is easy to form hydrogen bonds with water molecules and react with them, resulting in a decrease in the number of hydroxyl groups, which gradually makes the silicone adhesive lose its original characteristics and effects.

In order to avoid the melting problem of high-performance silicone structural adhesive, the following measures can be taken: firstly, the material and manufacturer of silicone structural adhesive should be known and confirmed before use; Secondly, in the process of use, attention should be paid to keeping the environment clean and dry to avoid silicone adhesive being in a humid environment for a long time; Finally, in the sealing, protection and storage of silicone adhesive, relevant standards and requirements should be followed to ensure the quality and use effect of silicone adhesive.
