ER2224

ER2224 Epoxy Resin ER2224 is a two-part filled epoxy encapsulation resin which has primarily been developed for encapsulation of electrical components. With its high thermal conductivity and excellent temperature stability, the product is ideal for dissipating heat in LED applications. High thermal conductivity ideal for heat dissipation within LED applications Good environmental protection offers good resistance to solvents and chemicals Wide operating temperature range good high temperature stability Very low water absorption good protection in high humidity conditions Approvals RoHS-2 Compliant (2011/65/EU): Yes UL Approval: No Typical Properties Liquid Properties: Base Material Epoxy Density Part A - Resin (g/ml) 2.32 Density Part B - Hardener (g/ml) 0.95 Part A Viscosity (mPa s 23C) 130000 Part B Viscosity (mPa s 23C) 25 Mixed System Viscosity (mPa s 23C) 20000 Mix Ratio (Weight) 14.6 : 1 Mix Ratio (Volume) 5.85 : 1 Usable Life (20C) 45 mins Gel Time (23C) 150 mins Cure Time (23C) 24 hours Cure Time (60C) 4 hours Cure Time (100C) 1 hour Colour Part A - Resin Off White Colour Part B - Hardener Light yellow Storage Conditions Dry Conditions: Above 15C, Below 35C Shelf Life 12 months Exotherm <30C (Measured on 100ml sample in a cylinder of diameter 49.4mm 23C) Shrinkage <1% Cured System: Thermal Conductivity (W/m.K) 0.81 Cured Density (g/ml) 2.13 Temperature Range (C) -40 to +150 Max Temperature Range (Short Term (C)/30 mins) 170C (Application and Geometry Dependent) Shore Hardness 25C D75 Colour (Mixed System) Off white Dielectric Strength (kV/mm) 10 15 Volume Resistivity (ohm-cm) 10 Flame Retardancy No Water Absorption (10 days 20C) <0.1% Water Absorption (1 hour 100C) <0.2% 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
