CONATHANE EN-21 is a two-component, liquid, low viscosity, low toxicity, room temperature curing polyurethane resin system. This system was formulated specifically for the potting, casting, embedding, and encapsulation of electronic circuits, components, and power devices. It is UL 94 HB certified. CONATHANE EN-21 is an easy-to-use, non-TDI, non MbOCA system. It can be hand mixed or machine dispensed and cured at room or elevated temperatures. CONATHANE EN-21 cures to yield an 80 Shore A elastomer and has the following outstanding characteristics:
CONATHANE EN-21 is ideal for use in potting transformers, coils, reed and mercury switches, inductors, solid state ignition systems, voltage regulators, ballasts, micro-circuits, rectifiers and printed circuit assemblies. |
