Among the types of potting glue, silicone potting is widely used because the mechanical properties of the colloid after curing are poor and it can be easily broken apart to replace components, while polyurethane potting glue does not have this property, which limits the use field. Only the reasonable application of silicone potting can achieve the expected potting effect.
How is the fluidity of silicone potting?
Two-component products need to mix and stir the two glues evenly before construction. Before construction, the glue has good fluidity and can penetrate into the gaps of small components to complete the purpose of comprehensive potting. The fluidity of the glue is related to the viscosity, and the viscosity can be adjusted according to user requirements. At present, brand products can achieve the purpose of customization, 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.
How long does it take for silicone potting to cure?
The overall curing time of the colloid is directly related to the curing environment temperature. In a normal temperature environment, it takes 12 hours to complete the curing, and various properties can reach the best state in about 7 days. In a heated environment, the overall curing time of the colloid is shortened. In an 80-degree environment, it only takes 15 minutes to complete the complete curing. The curing speed is relatively slow in low temperatures, and even incomplete curing may occur.
In order to make the silicone potting cure better, it is best to cure it at room temperature or in a heated environment. The temperature is low in winter and the curing speed is very slow. You can use warming curing or use winter low-temperature curing potting glue.
Only by fully understanding the performance and adaptability of silicone potting can better construction. During the construction stage, it is necessary to read the instructions carefully to avoid operating errors. The remaining unmixed glue should be sealed in time and stored in a cool and ventilated place without affecting the next use.
