Why do electronic devices need to be protected with potting compound

With the development of the electronic technology industry, electronic appliances are becoming increasingly small, so the requirements for stability and applicability are higher. Smaller electronic devices are more prone to problems and are difficult to repair. They are easily damaged by damp moisture and small vibrations, resulting in extremely easy damage to the devices.
In order to ensure that the quality and performance of silicone potting compound for electronics can be maintained for a long time, the overall performance has been improved. So there is the production of sealing adhesive.

Electronic potting compound is a protective adhesive used for potting electronic components, power supplies, and electronic products. After use, it can provide the best internal stress requirements for electronic components, ensure that components do not interfere with each other, avoid direct exposure of components to the air, prevent environmental erosion, improve the service life of components, improve product quality, achieve waterproof, dustproof, and thermal conductivity.
Today, we will mainly learn about silicone sealant.
Electronic components have a certain demand for adhesives, and potting silicone not only have stable dielectric insulation properties. It has excellent properties such as thermal conductivity, high elasticity, resistance to high and low temperatures, and vibration resistance.

characteristic
·Maintain good elasticity and prevent cracking during hot and cold alternations
·Excellent high-temperature electrical insulation
·Stable performance, resistant to external shocks
Advantages:
·The silicone potting adhesive is soft after curing, and has two forms: solid silicone rubber products and silicone gel, which can eliminate most of the mechanical stress and have the effect of shock absorption protection.
·Stable physical and chemical properties, with good resistance to high and low temperatures, capable of long-term operation within the range of -50~+200 ℃.
·Excellent weather resistance, able to provide good protection outdoors for over 20 years, and not prone to yellowing.
·It has excellent electrical performance and insulation ability, effectively improving the insulation between internal components and circuits after encapsulation, and improving the stability of electronic components.
·It has the ability to repair and replace sealed components quickly and conveniently.
That's why many components choose silicone sealant! Two component silicone sealant is the most common in component protection.
