Ep3115(#4) High thermal conductivity 0.7W/M.K Epoxy Potting Compound Sealant
Ep3115(#4) High thermal conductivity 0.7W/M.K Epoxy Potting Compound Adhesive
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
Epoxy is designed for staking and encapsulating electronics on circuit boards.
EP 3209A/B Two Component Black Epoxy Structural Adhesive
Product description
EP 3209A/B Epoxy adhesive is a room temperature/heat curing resin adhesive. This two-component bonding adhesive is designed for metal bonding, bonding of cube or SMC fiberglass parts, aluminum honeycomb plate splicing and magnetic steel tile bonding of motor products, ceramic film component sealing, internal structure bonding of lithium battery module, soft magnetic unit potting, high temperature sensor potting, etc.
EP 3209A/B epoxy adhesive can cure in both room temperature and heating environment. After thoroughly mixing component A and component B at 100:50 (weight ratio), the product cures within a certain period of time to form protection.
The cured glue has the following properties:
Resistance to moisture, dirt, and other atmospheric components
High strength, excellent adhesion
Good pollution resistance, low surface pretreatment requirements
No solvent, no curing byproducts
Excellent high and low temperature resistance, -50℃-180℃
Transformer oil resistance, low attenuation
It has good adhesion to glass fiber cloth, aluminum and plastic, aluminum and aluminum and steel plate
