The application field of adhesives is getting higher and higher, and it has become an indispensable material in the manufacturing industry. The richer the performance of adhesives, the higher the application field. silicone potting can be cured at room temperature or heated during the curing stage, which can meet different curing requirements. Can all silicone potting be cured by heating?
Is silicone potting suitable for heating curing?
Depending on the type, there are many types of silicone potting, which can be divided according to components, raw material ingredients, and vulcanization methods. Some types are suitable for heating curing, and will not release too much heat energy during the curing process, and will not affect electrical components. Other silicone potting cannot be cured by heating, such as single-component products. This type of product needs to be exposed to moisture in the air to undergo a vulcanization reaction. This type of glue is obviously more suitable for curing at room temperature.
The principle of heating and curing of silicone potting:
Two-component silicone potting is divided into glue A and glue B. After the two glues are mixed, heat energy will be released. After a certain period of time, a curing reaction will occur. At first, the surface of the glue becomes dry, and it slowly completes the complete curing. Placing it in a heated environment will help the two glues to react and cure faster. But the temperature should be controlled within 80 degrees as much as possible, because it only takes a few minutes to completely cure in an 80-degree environment. However, this situation is generally suitable for heating with a ratio of 1:1, and the AB ratio of 10:1 is not suitable for heating.
Does dust and impurities fall into the curing process of silicone potting?
There is a direct impact. The silicone potting can only play its performance after curing. Dust and water will not only reduce the viscosity of the glue, but also affect the waterproof, dustproof, and insulation properties. Therefore, impurities should be avoided during the curing process, and the curing environment should be standardized.
There are many types of silicone potting, and different types have different curing and construction requirements. Users need to understand clearly before purchasing. In order to avoid purchasing unqualified glue, you can consider cooperating with brand companies, such as TENSAN, which focuses on the research of potting glue and provides customized potting glue application solutions. It has a wide range of uses and can be applied to new energy, military, medical, aviation, shipbuilding, electronics, automobiles, instruments, power supplies, high-speed rail and other industries.
