Epoxy resin 049 two-component 100 g - insulating resin for electronics, component potting, encapsulation, circuit protection, chemical resistance, moisture and temperature resistance
Description
The two-component epoxy casting compound 149 (100 g) is an advanced casting material designed for potting and protection of electronic, telecommunication and radio components, offering excellent electrical insulation and mechanical strength to reliably safeguard against moisture, dust and external influences.
Benefits and Unique Features
- Very high viscosity of the mixture before curing
- Protection against moisture, dust and external influences
- Easy and precise application with uniform spread
- Dry-to-the-touch surface after curing
- High mechanical strength and hardness
- Excellent electrical insulation properties
- Safe formulation for sensitive electronic surfaces
Properties and Applications
- Appearance: Yellow liquid (Component A) / Colorless liquid (Component B) – allows visual control during application.
- Density at 25 °C: 1.16 g/cm³ (A) / ~0.98 g/cm³ (B) – ensures optimal penetration into gaps.
- Viscosity at 25 °C: 20 000–30 000 cP (A) – facilitates even spreading.
- Gel time at 25 °C: ~33 min – allows precise positioning of components before curing.
- Hardness after curing: 97° Shore (A) – provides a durable, resistant coating.
- Deflection temperature (Martens): 90–110 °C – thermal resistance under demanding conditions.
- Applications: Coils, transformers, capacitors, resistors, cable connectors, and telecommunication or radio equipment.
