Among the types of potting glue, silicone potting glue is widely used because the colloid has poor mechanical properties after curing and can be easily broken apart to replace components. However, polyurethane potting glue does not have this performance, thus limiting the field of use. Only reasonable application of silicone potting glue can achieve the desired potting effect.
How is the fluidity of silicone potting glue?
Two-component products need to be mixed and stirred evenly before construction. Before construction, the glue has good fluidity and can penetrate into the gaps of fine 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. Currently, brand products can achieve customized purposes, 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 used in new energy, military industry, medical, aviation, shipbuilding, electronics, automobiles, instruments, power supplies, high-speed rail and other industries.
How long does it take for silicone potting glue 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 curing, and it takes about 7 days for various properties to reach their optimal state. 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 complete curing. The curing speed is relatively slow at low temperatures, and may even fail to cure completely.
In order to make the silicone potting glue solidify better, it is best to cure it at room temperature or in a heated environment. In winter, the temperature is low and the curing speed is very slow. You can use temperature-increasing curing or use low-temperature curing potting glue in winter.
Only by fully understanding the performance and adaptability of silicone potting glue can we achieve better construction. During the construction stage, it is necessary to read the instructions carefully to avoid operational errors. The remaining unmixed glue should be sealed in time and stored in a cool and ventilated place so that it will not affect the next use.
