Precautions for use of silicone platinum vulcanizing agent_ Keep the following points in mind

In the vulcanization molding process of silica gel, there are many vulcanizing agents that can be used, including the common ones such as the D24, D25, and the platinum vulcanizing agent that we will talk about today. Today, Xiaokang will mainly tell you the precautions for using the silicone platinum vulcanizing agent, so that we can use it safely, reasonably, and efficiently in future applications. Let's take a look together.
Application Fields of Silicone Platinum Vulcanizing Agent
As we know, platinum vulcanizing agents, due to their excellent environmental performance, are commonly used in medical, food, infant and child products that require high hygiene performance, or have low vulcanization temperatures. They have the characteristics of low vulcanization temperature and fast vulcanization speed, and have the advantages of environmental protection, high efficiency, and odorless compared to traditional peroxide vulcanization systems. Of course, the performance is so excellent, and its price is slightly higher.
Precautions for Use of Silicone Platinum Vulcanizing Agent
Precautions for use of C-80AB silicone platinum vulcanizing agent

1. During hot air vulcanization, attention should be paid to the selection of rubber materials, otherwise bubbles will occur;
2. Platinum is used for sulfur addition, and N is not allowed to be added to the raw material P. S atoms or heavy metal components (such as hydrogen sulfide, mercaptan) can cause a large number of needle holes on the surface of the product, and can lead to incomplete vulcanization of the product and mold adhesion;
3. During rubber mixing, the temperature should not be too high, preferably not exceeding 40 ℃. It is recommended to open the mixer and use ice water for circulation cooling Best results;
4. After adding platinum agents A and B, it is necessary to place them in a space with a temperature not exceeding 25 ℃ and use them within 4-8 hours to prevent room temperature crosslinking.
5. Do not add this product when the temperature of the rubber mixing and mixer drum is higher than 45 degrees Celsius. Wait until it is cooled, otherwise there will be dead material during rubber mixing;
