Silicone sealants are divided into two-component and one-component. Currently, one-component silicone sealants are used in a wide range of fields. They can be used in both electrical appliances and electronics. There is also a good fixation effect. So how long does it take for the silicone sealant to cure?
Two-component silicone potting glue is a kind of potting material that is mixed with AB two components and cured by normal temperature or heating. The main function of potting is sealing, waterproof, heat conduction, etc.; it can be divided into addition type and type according to different curing methods. condensation type. Addition type potting glue generally has a ratio of AB components of 1:1, A component is black, B component is white, and after mixing, it is gray and black.
Thermally conductive silicone gasket is a kind of thermally conductive interface material. Its main function is to fill the gap between the heat sink and the heat sink, or to reduce the contact thermal resistance between the two. According to Fourier's thermal conduction theory, the thermal resistance is inversely proportional to the thickness of the material, the thicker the material, the higher the thermal resistance value, so when choosing to use it, the thinner the better.
Anyone who uses solder paste knows that solder paste needs to be refrigerated, so why should solder paste be refrigerated? In fact, cold storage of solder paste is to slow down the reaction speed of FLUX and tin powder, thereby prolonging the storage time, so solder paste is usually stored in a refrigerator (2-10°C) or a freezer.
Some people don't know why to use thermal paste? Use it in the gap between the radiator and the CPU to fill and improve heat dissipation. With the help of this adhesive, the components can be tightly bonded together and conduct heat better.
