CONATHANE EN-2521 is a two-part filled polyurethane resin system. The system features good handling properties and working life. EN-2521 can be cured at room or elevated temperatures without the formation of voids. The cured compound has excellent water resistance and is exceptionally resistant to thermal shock. Other outstanding properties of this system include low exotherm, very low stresses during cure, low shrinkage, and very good electrical properties. CONATHANE EN-2521 is recommended for potting applications where exceptional performance in the temperature range of -65°C to 130°C is required. It is particularly useful in the encapsulation of modules, strain sensitive circuitry, transformers, and coils. |
