In the field of modern electronic manufacturing, epoxy sealant has become the preferred material for electrical insulation, mechanical protection, and environmental sealing. Whether it’s power modules, automotive electronics, LED drivers, transformers, or sensors, epoxy potting adhesive provides reliable and long-lasting packaging solutions with its excellent performance.
Epoxy sealant
What is epoxy sealant?
Epoxy potting adhesive is a two-component or one component adhesive based on epoxy resin, commonly used for potting protection of electronic devices. Its characteristics are high adhesive strength, strong thermosetting, low shrinkage rate, and the formation of a dense and hard protective layer after curing. It can effectively prevent water, dust, and corrosion, and has excellent electrical insulation performance.
The core advantages of epoxy sealant
Excellent electrical insulation performance
Prevent current leakage and breakdown, and protect the stable operation of components in high voltage environments.
Excellent weather resistance and heat resistance
Capable of withstanding temperature fluctuations ranging from -40 ° C to 150 ° C, suitable for outdoor and high-temperature work environments.
High adhesion force
It can firmly adhere to the surfaces of various materials such as metal, plastic, glass, ceramics, etc., enhancing the overall structural strength.
Strong seismic and impact resistance performance
After curing, it forms a tough structure that effectively absorbs external stress and prevents component detachment or damage.
Good flame retardancy
Multiple products have achieved UL 94V-0 flame retardant rating, meeting electrical safety regulations.
Application fields of epoxy sealant
Epoxy sealant is widely used in the following industries and products:
Power module and adapter: improve voltage and moisture resistance levels
LED driver power supply: prevents electrical breakdown and extends service life
Automotive electronics (such as sensors, control modules): heat-resistant and earthquake resistant, ensuring driving safety
Transformers and Inductive Components: Improving Insulation and Reducing Noise
New energy battery pack: Enhance packaging strength to prevent internal short circuits
Typical recommendation: ELAPLUS epoxy sealant EP 1712
EP 1712 is a two-component epoxy potting material with the following characteristics:
Good toughness and high hardness
High hardness and excellent crack resistance after curing
Heat resistance of over 150 ° C, short-term up to 180 ° C
Excellent water resistance and chemical corrosion resistance
Compliant with UL 94V-0 flame retardant certification
Very suitable for high reliability applications such as power modules, charging stations, ignition coils, transformers, etc.
