Applications of ET 245 for Applications of ET 245 for


Hardener ISO 11026 B

Self-extinguishing PU for potting & encapsulation

  • Certified UL 94 V0
  • Available in black or white
  • Dielectric insulative
  • 45 Shore D hardness

Characteristics and applications :

Two-component polyurethane system, semi-rigid, self-extinguishing V0 (thickness ≥ 6mm) homologated in accordance with UL 94 standard available in white (standard version) or others (contact us). Particularly suitable for moulding and encapsulating electronic or electrotechnic materials when the application requires an excellent fire resistance, with good behaviour against thermal shocks, a low stress on components and good heat evacuation.
Halogen-free, non-magnetic and RoHS compliant.

Processing :

Mix thoroughly ET 245 A V0 resin for each use before mixing to ISO 11026 B. Weighing & mixing can be done manually or by using a two-component dispensing machine. Materials and pieces should be dry and exempt of dust. Moulds and pieces could be heated if necessary.

The release time may vary depending on the shape, thickness and processing temperature. To avoid air entrapments, it is recommended to degas the mix under vacuum for about 2 to 3 minutes before casting.
