Electrical sealant is used for bonding, sealing, potting and coating protection of electronic components. Before curing, the sealant is liquid and has fluidity. The viscosity of the glue varies according to the material, performance, and production process of the product. The sealant can only realize its use-value after it is completely cured. After curing, it has the performance of waterproof, moisture-proof, dust-proof, insulation, heat conduction, leakproofness, corrosion resistance and temperature resistance. There are many types of electronic sealants. By material type, there are currently three most commonly used, namely epoxy resin sealant, electrical sealant silicone, and polyurethane sealant.
The production cost of electrical sealant silicone is slightly higher than that of other types of sealant, but it has good performance and a long application period, which is especially suitable for mass automated production line operations. It can also be specially used for coating, pouring, and potting protection of precision electronic components, solar energy, backlight and electrical modules for waterproofing, moisture-proofing, and gas pollution prevention.
1. Electrical sealant silicone can be used in the coating, pouring, and potting protection of electronic components. It can protect electrical components from moisture and water intrusion. It can also have other insulation and anti-flame retardant properties to ensure the electrical appliances are safer to use, and safety hazards are less.
2. Electrical sealant silicone can be used in solar energy manufacturing. It has good weather resistance, oxidation resistance and corrosion resistance, and has good bonding performance and high-temperature resistance. It can be used between -60℃～200℃, so even in harsh outdoor conditions, it will not cause cracks, melt, or other issues.
3. Electrical sealant silicone can also be used in the bonding potting of led lights, which can take effect in bonding, fixing, waterproof, and flame-retardant.
In general, electrical sealant silicone has good adhesion and sealing performance to many substrates, has excellent electrical insulation performance, and can withstand changes in heat and cold between -60℃～200℃ without cracking and maintain elasticity. It has better thermal conductivity after filling and modifying with thermally conductive materials. The use of electrical sealant silicone can effectively improve the heat dissipation capacity and moisture resistance of electronic components and prolong the service life of electronic equipment. Moreover, the electrical sealant silicone is soft after curing, which is convenient for the maintenance of electronic equipment. The sealant can automatically heal after being cracked by external force and without affecting use. Compared with the epoxy resin sealant, it may strain the electronic components, and has worse weather resistance causes small cracks which affect moisture resistance and temperature resistance. Therefore, epoxy resin sealant can only be suitable for electronic equipment that has no special requirements on the environment.
