Silicone potting can meet the user's requirements for adhesive curing time. As long as the curing environment temperature is appropriately changed, the estimated curing time can be achieved. Because there are many types of silicone potting, different types have certain requirements for curing methods and temperatures, and you need to carefully check the instructions before use.
Can all types of silicone potting be cured by heating?
No, silicone potting is divided into one-component and two-component. One-component silicone potting relies on air humidity to undergo vulcanization reaction and can be cured at room temperature, but cannot be cured by heating. Most two-component silicone pottings can meet the needs of heating and curing. It only takes more than ten minutes to complete the overall curing at a high temperature of 80 degrees. However, generally speaking, only silicones with A:B=1:1 can be cured by heating.
Are there any disadvantages to heating and curing silicone potting?
As long as the silicone potting can be cured at room temperature, there will be basically no effect if the heating environment temperature does not exceed 80 degrees. Once the heating temperature exceeds 80 degrees, the overall curing only takes a few minutes, and the initial curing and thorough curing are completed almost at the same time. There are residual bubbles in the cured colloid.
During the high temperature curing process, the glue will release some heat energy. If the electrical components have poor bearing capacity, the stress in the colloid will affect the electrical components. Therefore, even if it is a two-component silicone potting, you need to understand the composition, usage and operation process before using it, and you cannot operate it blindly.
The two-component silicone potting is slightly viscous and has a certain fluidity. It can penetrate every corner of the substrate during construction. It can be constructed by hand or machine. If there are requirements for the viscosity of the glue during the construction process, you can contact the manufacturer to adjust it. Therefore, it is best to cooperate with a brand company when purchasing, and it is more assured to use it, 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.
