ER2223 Electrolube

PROVISIONAL TDS ER2223 Epoxy Resin ER2223 is a two-part filled, high Tg, low viscosity epoxy encapsulation resin which has primarily been developed for encapsulation of electrical components that require high temperature resistance. Low viscosity aids ease of potting difficult and complex geometries Good chemical resistance offers good protection in a range of environments Excellent adhesion to a wide range of substrates Wide operating temperature range excellent high temperature performance Typical Properties Liquid Properties: Base Material Epoxy Density Part A - Resin (g/ml) 1.15 Density Part B - Hardener (g/ml) 0.96 Part A Viscosity (mPa s 23C) 600-1000 Part B Viscosity (mPa s 23C) 50-100 Mixed System Viscosity (mPa s 23C) 150-250 Mix Ratio (Weight) 3.45 : 1 Mix Ratio (Volume) 2.90 : 1 Usable Life (20C) 30 mins Gel Time (23C) 90 mins Cure Time (23C) 24 hours Cure Time (60C) 4 hours Cure Time (100C) 1 hour Colour Part A - Resin Black Colour Part B - Hardener Colourless to light brown Storage Conditions Dry Conditions: Above 15C, Below 35C Shelf Life 12 months Shrinkage <1% Cured System: Cured Density (g/ml) 1.10 Temperature Range (C) -40 to +180 Max Temperature (Short Term (C)/30 mins) (Application 210C and Geometry Dependent) Glass Transition Temperature (C) 140 Shore Hardness 25C D80 Shore Hardness 60C D80 Shore Hardness 100C D75 Colour (Mixed System) Black Dielectric Strength (kV/mm) 12 15 Volume Resistivity (ohm-cm) 10 Flame Retardancy No Water Absorption (10 days 20C) <0.25% Water Absorption (1 hour 100C) <0.25% Coefficient of Thermal Expansion (ppm) 70 Mixing Procedures Resin Packs When in Resin pack form, the resin and hardener are mixed by removing the clip and moving the contents around inside the pack until thoroughly mixed. To remove the clip, remove both end caps, grip each end of the pack and pull apart gently. By using the removed clip, take special care to push unmixed material from the corners of the pack. Mixing normally takes from two to four minutes depending on the skill of the operator and the size of the pack. Both the resin and hardener are evacuated prior to packing so the system is ready for use immediately after mixing. The corner may be cut from the pack so that it may be used as a simple dispenser. 1 3 2 4 5 6
