Electronic sealants are a kind of sealing material that can change shape according to the shape of the seal. This material is sticky and adheres to the surface of the substrate, but will not damage the electronic components. It has a wide range of uses and can be used in electronics, automobiles, electronic instruments and other fields.
Nowadays, the performance of electrical appliances is getting better and better, and they can meet the requirements of light weight, complete performance, and long-term use without burning. The reason for such progress is that thermal conductive materials are added during manufacturing to enhance the performance of the radiator. This material is thermal grease. Thermal grease is in the state of silicone grease. Whether before or after use, the performance remains unchanged. It has no adhesive properties and adheres to the surface of the substrate to exert heat dissipation performance. Why is there no adhesion? Will it fall off?
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.
Silicone sealants are mainly composed of polydimethylsiloxane and cross-linking agents, fillers, plasticizers, and coupling agents. Such adhesives are very popular in the industrial manufacturing industry and have many uses. After use, they can not only play a good bonding role, but also be waterproof, moisture-proof, anti-evacuation, and adapt to hot and cold changes.
In order to achieve better performance, electrical appliances now use a variety of adhesives in the manufacturing process, such as sealants and potting glue. These adhesives mainly play a role in protecting electrical appliances, preventing water ingress, and ensuring service life. Thermal grease does not have any bonding properties, but it occupies a very important position in the electrical appliance manufacturing industry and cannot be ignored.
With the continuous development of industry, the requirements for silicone potting are increasing. Traditional adhesives can no longer meet the production needs of various industries, and environmentally friendly and easy-to-use products are urgently needed. Understand the performance and effect of silicone potting and use it in a suitable environment.
