Categories: Polymer; Adhesive; Thermoset; Polyurethane, TS; Thermoset Polyurethane, Adhesive

Material Notes:
Polyurethane Potting and Encapsulating Systems
Conathane® EN-2500 series polyurethane potting and encapsulating systems from Cytek have varying degrees of worklife, viscosity and hardness for many specific potting and encapsulating applications such as modules, strain-sensitive components, transformers, and coils. All 2500 series systems exhibit excellent performance when exposed to adverse environments and temperature ranges between -55°C and +130°C.

Cytec (Conap) EN-2523 Potting and Encapsulation Adhesive

  • Passes Thermal Shock Test (10 Cycles, -65°C to 130°C)
  • Non-Nutrient Fungus Resistance (MIL-STD-810B)
  • Mix Ratio: 20/100 (by Weight)
