Sealant is a kind of glue that can change its shape according to the shape of the sealing surface. This glue has high viscosity and is not easy to flow. It has good bonding performance after curing. The main raw materials are asphalt, natural rubber, and then some plasticizers, curing agents, accelerators, etc. are added. It can be used in automobiles, buildings, and electronic instruments. After curing, the waterproof performance is relatively good.
After curing, silicone potting is generally soft. It is elastic and has good bonding performance when pinched by hand. It is commonly used in the potting of electronic components. During the construction stage, is the worker's operation process important? What are the reasons? Why is the operation process of potting glue important?
Thermal grease is a heat dissipation material. The specific heat dissipation "mission" still depends on the radiator. Thermal grease is mainly used to fill gaps, so that the radiator and the heating element are fully in contact, showing a better heat dissipation effect. As a "bridge" between the radiator and the heating element, the application method of thermal grease cannot be ignored, otherwise it will have no effect.
Faced with a variety of adhesives, silicone potting is in greater demand. The reason is that the adhesive has low viscosity and good adhesion, which is suitable for use in many industrial fields. Let it cure naturally, it will play a better effect.
As a kind of potting glue, silicone potting can be divided into several types if carefully classified. Each silicone potting plays its own performance in the field of use and carries an important "mission". Silicone potting has a wide range of uses, but its advantages cannot be ignored. The specific advantages are as follows.
There are obvious differences between silicone sealant and two-component sealant. The two are used in different fields, and the methods of use and prices are even more different. silicone sealant relies on air humidity to vulcanize. It can automatically cure without heating after construction. It has the characteristics of slow curing speed during the curing stage. It usually takes 24 hours to cure, and the performance will be stable after 72 hours.
