Unlike most types of adhesives that are not able to withstand high temperatures, the electrical potting compound is able to provide heat resistance that can only be offered by an epoxy. In addition to this, it is flexible in nature and can be used whenever flexibility is required. Its flexibility is generally compared to that of urethane. It offers maximum protection by encasing the electrical circuits from external hazards. It can be used in place of silicon casing when it comes to offering maximum protection. Even though the potting compound is compared to urethane in terms of flexibility, it is not vulnerable to water and water based compounds like urethane. It is able to protect the circuit board from water or moisture contamination.
The electrical potting compound is also known for its flexibility when it comes to temperature. It can withstand temperatures as low as -75 degrees Celsius and as high as 150 degrees Celsius. This temperature range can accommodate virtually all types of electrical applications. When the compound is exposed to very low temperatures, it contracts slightly and maintains a tough seal. When exposed to high temperatures, it expands slightly but does not crack. Therefore, the coating provides the circuit with maximum protection against water, moisture and corrosive media at all times.
Electrical potting compounds generally have an anti-microbial property. This means that whenever they are exposed to high levels of humidity or moisture, they inhibit the growths of molds and mosses. They keep the electrical circuit in its new state throughout its lifetime. Some epoxies that are used to insulate circuit boards are generally hard on sensitive parts. However, with the use of an appropriate potting compound, one is assured of gentle protection that hardly damages sensitive circuitry. The embedment stress generated after the potting compound cures is generally low and does not affect the alignment of the electrical circuit.
