The so-called epoxy adhesive is a liquid or solid adhesive composed of epoxy resin AB adhesive, accelerator, curing agent, diluent, modifier, filler, etc. So what is the adhesive process of epoxy adhesive? It is a very complex physical and chemical process, which includes several steps of adhesion, wetting, curing, etc. After this step is completed, a three-dimensional cured product of the cross-linked structure will be generated, and then it can be adhered. Things into a whole. Then the adhesive properties of epoxy adhesives are strength, heat resistance, corrosion resistance, impermeability, etc. What factors do these all depend on? The aspects involved are very light, not only depends on the structure and performance of the adhesive and the structure and adhesive characteristics of the surface of the adherend, but also closely related to the manufacturing process and storage of the adhesive and joint design, and even the bonding process. In addition, it will also be restricted by the surrounding environment (stress, temperature, humidity, media, etc.). It can be seen that epoxy adhesives will be subject to many objective effects. Therefore, the application of epoxy adhesives is relatively complicated. Its performance must be compatible with the above-mentioned factors that affect the bonding performance in order to obtain the effect in use. Objects or different use environments, or different bonding conditions are used, the final bonding results will be very different.
