Elantas EN-2550 (Conap) Potting and Encapsulation Adhesive
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-2550 Potting and Encapsulation Adhesive Specifically 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) Information provided by Cytec, subsequently acquired by Elantas.
