Ep3115(#2) High thermal conductivity 1.5W/M.K Epoxy Potting Compound Adhesive
Ep3115(#2) High thermal conductivity 1.5W/M.K Epoxy Potting Compound Adhesive
For a high thermal conductivity potting compound/adhesive in the1.5w/mk range, the industry-standard formulation . This Black, two-part epoxy system provides superior heat dissipation for demanding electronics while doubling as a flame-retardant structural adhesive that meets the UL94 V-0 standard.
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.
Typical Applications
Encapsulating power supplies, transformers, and inverters.
Potting LED drivers and heavy-duty power tool electronics.
Heat sink attachment and high-power die bonding
Epoxy is designed for staking and encapsulating electronics on circuit boards.
PU 6030 Light yellow translucent Polyurethane potting compound
PU 6030 is a two-component solvent-free polyurethane material at room temperature or heat curing. It is light yellow and transparent after curing. It is used for two-component sealing, filling, flame and other fields. The raw material does not contain heavy metals, green environmental protection, wide process operability, high physical properties of the finished product, and good adhesion to the substrate. Room temperature and heating curing can be, can be deep curing, curing less heat, low shrinkage rate; Excellent
flexibility after curing, with good flame retardant effect.
l Excellent low temperature characteristics, excellent weather resistance
l Excellent flame retardancy, 94 V-0
l Excellent electrical insulation, stability
Typical application
l This product is often used in electronic capacitors, automotive electronic module potting;
l Household appliances such as lampblack stove, microwave oven, rice cooker, washing machine,
l Good water resistance, moisture resistance, water absorption is very low
l Good adhesion to most metals and plastics air conditioning control PCB board filling glue seal;
l Life smart toilet, induction toilet, metal induction garbage can circuit board and magnetic coil of moisture and waterproof potting protection.
