Product description
Epoxy Potting Compound 149 is a two-component, epoxy-based potting compound developed to protect and encapsulate electronics and circuit boards in enclosures. The compound forms a strong protective layer around components and circuit boards. It resists moisture, dust, chemicals, and mechanical stress (e.g. vibrations). The potting compound has excellent insulating properties and provides strong adhesion to a wide range of materials.
The product is used under demanding conditions, for example:
- Protection of automotive electronics
- Vibration and contamination protection for power tools and industrial electronics
- Moisture protection for outdoor electronics
- Encapsulation of marine electronics
Properties
- Insulating properties: Provides reliable protection against electrical breakdown and short circuits
- Chemical resistance: Withstands exposure to many aggressive chemicals, including acids and bases
- Wide range of applications: Suitable for potting coils, transformers, capacitors, resistors, connectors, and cable ends
- Strong adhesion: Bonds effectively to metals, plastics, and ceramics
- Weather resistance: Retains its properties even under challenging temperature and weather conditions
