Material Notes:
Polyurethane Potting and Encapsulating SystemsConathane® 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-2550 Potting and Encapsulation AdhesiveSpecifically formulated to impart a flame resistance that will meet U.L. 94 V-O rating in 1/8" test sample.Passes Thermal Shock Test (10 Cycles, -65°C to 130°C)Non-Nutrient Fungus Resistance (MIL-STD-810B)Mix Ratio: 17/100 (by Weight)
