EKP-204 T White Thermally Conductive Silicone Compound
Name
EKP-204 T White Thermally Conductive Silicone CompoundProduct description
A two-component white, thermally conductive, room-temperature-curing compound for bulk sealing with heat dissipation, encapsulation and protection of electrical and electronic products.
After mixing with the catalyst, it cures at room temperature to form a dense elastic mass. It cures uniformly throughout the volume regardless of casting depth or enclosure geometry.

Our products
White thermally conductive RTV-2 compound for electronic potting with heat dissipation and protection against moisture and vibration.
Fields of application
- Potting of PCBs, LED drivers, transformers, chokes and power supplies.
- Battery packs: thermal management and improved mechanical integrity.
- Inverters and DC/DC converters, including automotive and solar-power equipment.
- Electromagnet coils, high-voltage transformers and inductors.
- Junction boxes, industrial instruments and electrical machines.
Benefits
- Thermal conductivity of 0.5–0.6 W/(m·K) for heat dissipation from processors, LEDs, power transistors and battery cells.
- Bulk curing in thick sections.
- High dielectric and electrical-insulation performance.
- Resistance to moisture, UV, ozone, vibration and temperature cycling.
- Resistance to oils and gasoline; cure time can be controlled by catalyst dosage.
Application methods
- Thoroughly premix the EKP-204 T base in its original container until homogeneous.
- Add 3–5 wt.% KHT catalyst and mix for 3–5 minutes.
- Pour into the prepared enclosure or mould on a level surface; use a release agent for moulding only if required.
Application
KHT catalyst is not included in the standard supply and must be ordered separately.
A release agent is not recommended when sealing finished products.
Storage
Store in the tightly closed original container in accordance with the safety data sheet and certificate of analysis.
After the warranty period, use only after a successful trial mix.
Safety information
- Provide effective ventilation.
- Wear protective gloves and safety glasses.
- Avoid contact of the compound and catalyst with skin, eyes and the respiratory tract.
