2. Working principle of SA-102
2.1 Thermal activation mechanism
Thermal sensitivity of SA-102 is one of its core characteristics. At room temperature, SA-102 is in an inert state and will not have any effect on polymer materials. However, when the temperature rises to its activation temperature (usually 150-160°C), SA-102 will quickly activate, starting to catalyze the crosslinking reaction of polymer materials.
2.2 Promoting effects of cross-linking reaction
Crosslinking reaction is a key step in the processing of polymer materials. Through cross-linking reactions, chemical bonds are formed between polymer chains, thereby enhancing the mechanical properties and thermal stability of the material. SA-102 accelerates the progress of the crosslinking reaction by providing an active site, so that the material reaches an ideal crosslinking degree in a short time.
2.3 Mechanism for improving surface quality
SA-102 promotes crosslinking reactions to make the surface of polymer materials more uniform and dense. This not only reduces surface defects, but also improves the material's wear and corrosion resistance. In addition, the uniform distribution of SA-102 also ensures smoothness of the material surface and avoids surface roughness caused by uneven crosslinking.
III. Application scenarios of SA-102
3.1 Automobile Industry
In the automotive industry, surface quality directly affects the appearance and durability of a vehicle. SA-102 is widely used in the production of automotive interior parts, exterior parts and engine parts. By using SA-102, the surface of automotive parts is smoother, reducing wear and corrosion problems caused by surface defects.
3.2 Electronics
The shells and internal structural parts of electronic products require extremely high surface quality. The application of SA-102 in electronic products not only improves the aesthetics of the shell, but also enhances its impact resistance and heat resistance. This is of great significance to extend the service life of electronic products.
3.3 Medical Devices
The surface quality of medical devices is directly related to their safety and effectiveness. The application of SA-102 in medical devices ensures smoothness and sterility of the instrument surface and reduces the risk of infection caused by surface defects.
