Ep3115 Potting Compound 0.6W/MK Epoxy Thermal Adhesive Waterproof Sealant
Ep3115 Potting Compound Epoxy 0.6W/mk Thermal Adhesive Waterproof Sealant Electronics
Thermally conductive epoxy potting sealants are designed to dissipate heat from sensitive electronic assemblies while providing excellent electrical insulation. Unfilled epoxies typically have low values of 0.14w/mk. So compound of 0.6W/mk use ceramic or metallic fillers to significantly boost heat transfer.
Key Performance Properties
Heat Dissipation: Efficiently transfers heat away from hot spots (like CPUs and transformers) to heat sinks, preventing thermal runaway.
Environmental & Electrical Protection: Offers superior dielectric strength for electrical insulation alongside rugged resistance to moisture, humidity, and vibrations.
Formulation & Cure: These are frequently two-part (A:B=100:15) systems that cure either at room temperature or with mild heat
Typical Applications
Encapsulating PCBs and electronic modules to create an environmental seal.
Potting transformers, coils, and relays to improve heat transfer and prevent overheating.
Insulating AC/DC power supplies and automotive electronics
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
