Ep3115(#8) Encapsulation With Epoxy Resin Protects Electric Motor Stators

A 0.7 W/m·K epoxy potting compound sealant is a specialized, moderately thermally conductive resin designed to protect electronic assemblies while actively dissipating heat.

EP 3225(4#)A/B has the following characteristics:

l Excellent bond and cracking resistance

l Low CTE linear expansion coefficient

l High thermal conductivity

l Excellent electrical insulation and stability

l It is used in the temperature range of -50℃-180℃

l Water absorption is very low, good water and moisture resistance

l Excellent adhesion to metals (iron, aluminum and copper)

Key Features to Expect

Operating Temperatures: Designed for extreme environments, typically spanning -50~+200℃

(with some specialty formulations withstanding up to +200℃

Electrical Isolation: While highly conductive to heat, these epoxies offer excellent electrical insulation, protecting circuitry against voltage spikes and static.

Environmental Resistance: The cured compounds create a resilient barrier against moisture, salt water, humidity, and mild chemicals. 

Common Applications

• Power Supplies: Encapsulating transformers, drivers, and power converters to mitigate heat build-up.

• Automotive Electronics: Protecting under-the-hood sensors, control modules, and electric vehicle battery components from harsh environments.

• Industrial Controls: Sealing heavy-duty relays, switches, and outdoor circuit boards against moisture and dust.

• LED Drivers: Wicking away heat from high-brightness lighting modules to significantly extend their operational lifespan

• Electric motor stators have been encapsulated with epoxy resin for protection from moisture, salt spray, steam and contaminants that can cause corrosion with resultant motor failure.

Epoxy is designed for staking and encapsulating electronics on circuit boards.
