In power equipment and industrial electronic systems, the dielectric switch copper plate plays a dual role in current conduction and insulation protection. It must ensure reliable conductivity and operate stably for a long time in harsh environments such as high voltage, high temperature, and humidity.
Therefore, the requirements for bronze medals and their packaging materials are extremely strict – thermal conductivity, moisture resistance, insulation, and crack resistance are all indispensable.
And this is precisely the strength of Elaplus EP 1710 epoxy potting material.
1、 Product Introduction: EP 1710 Epoxy Sealing Material
EP 1710A/B is a two-component solvent-free ambient temperature curing epoxy sealant developed specifically for applications requiring thermal protection such as motors, automotive electronics, power tools, reactors, and instruments.
This product performs particularly well in the copper packaging application of dielectric switches, effectively isolating moisture and dust, and improving system stability and safety.
2、 Core performance characteristics
✅ Excellent adhesion and crack resistance
EP 1710 has a high-strength molecular network structure and can firmly bond with metal substrates such as copper, aluminum, and stainless steel. Its toughness design can effectively absorb thermal stress and prevent cracking and delamination caused by thermal cycling.
✅ Low coefficient of linear expansion (CTE)
Traditional epoxy sealant is prone to failure due to thermal expansion mismatch under alternating high and low temperatures. EP 1710 achieves low CTE characteristics and ensures structural dimensional stability by optimizing the formulation system.
✅ High thermal conductivity
In response to the concentrated heating characteristics of dielectric bronze plates, EP 1710 adds high-efficiency thermal conductive fillers to achieve excellent thermal conductivity in the industry, which can quickly conduct internal heat and reduce hot spot temperature rise.
✅ Excellent electrical insulation and long-term stability
After curing, a dense three-dimensional cross-linked structure is formed, with high insulation resistance and excellent dielectric strength, ensuring no leakage risk between copper plates and maintaining stable electrical performance even after long-term operation.
✅ Excellent waterproof and moisture-proof performance
The water absorption rate is extremely low, which can effectively prevent moisture intrusion and corrosion, and is suitable for complex working conditions such as high humidity and high salt spray.
✅ Outstanding temperature resistance performance
It can be used stably for a long time in an environment of 150 ℃~180 ℃, ensuring that the dielectric switch system still has reliable protection capability during high temperature operation.
3、 Typical application scenarios
EP 1710 is not only suitable for copper plate sealing of dielectric switches, but also widely used in:
Sealing of motor stator and rotor
Reactor coil protection
Sealing of electric tool control module
Automotive Electronic Control Unit (ECU)
Instrument power module and relay packaging
In these applications, EP 1710 can provide excellent thermal conductivity and insulation protection performance, helping electronic devices maintain reliable operation under high power density conditions.
In high-power and high-voltage electrical equipment, reliable packaging of dielectric switch bronze plates is the key to ensuring system safety and lifespan.
EP 1710 provides a stable and reliable solution for this critical component due to its high thermal conductivity, low CTE, excellent insulation and moisture resistance.
Whether it’s industrial equipment, automotive electronics, or new energy systems,
EP 1710 is your top choice for high-performance potting protection.
