Name
EKP-204 Transparent Silicone Potting CompoundProduct description
A professional two-component, room-temperature-curing material for bulk potting, encapsulation and sealing of electronic components, printed circuit boards and electrical assemblies.
After addition of the catalyst, it cures at room temperature to form a transparent, elastic rubber-like mass. It cures uniformly throughout the volume regardless of casting depth or enclosure geometry.

Fields of application
- Potting and encapsulation of electronic equipment, instruments and printed circuit boards.
- Sealing of electromagnets, sensors and electrical assemblies.
- Production of elastic gaskets, seals and flexible moulds.
Benefits
- Bulk curing in thick sections without a depth limitation.
- Stable dielectric and electrical-insulation performance.
- Optical transparency for visual inspection of encapsulated assemblies.
- Resistance to UV radiation, ozone, oxidising agents, weathering and radiation exposure.
- Elasticity and hydrophobicity over a wide temperature range; resistant to oils and gasoline.
Application methods
- Clean and degrease the surfaces; thoroughly premix the base in its original container.
- Add 3–5 wt.% catalyst and mix for 3–5 minutes, scraping the bottom and walls of the container.
- Vacuum-degas if required, then pour into the prepared enclosure or mould on a level surface.
Application
The allowable catalyst range is 1–7 wt.%. Catalyst level controls pot life and cure rate.
KHT catalyst is not included in the standard supply and must be ordered separately.
Storage
Store in the tightly closed original container. Storage conditions and warranty period are stated in the manufacturer’s safety data sheet and certificate of analysis.
After the warranty period, use is permitted only if a trial mix confirms that the technical properties remain unchanged.
Safety information
- Provide effective supply and exhaust ventilation.
- Wear protective gloves and safety glasses.
- Avoid contact of the compound and catalyst with skin, eyes and the respiratory tract.
