Technical Data Sheet ER2183 Epoxy Resin Product Description ER2183 is a flame retardant, thermally conductive, two part potting and encapsulating compound. The flame retardant technology used is of a clean type leading to relatively low toxicity fumes and low smoke emission. Features Excellent thermal conductivity Meets UL94 V-0 approval Low viscosity Low shrinkage and exotherm Good chemical and water resistance Excellent electrical properties Non-toxic Free of abrasive fillers, low wear on dispensing machinery Approvals: RoHS Compliant Yes UL Approval Meets Typical Properties: Liquid Properties: Base Material Epoxy Density Part A - Resin (g/ml) 2.13 Density Part B - Hardener (g/ml) 0.93 Part A Viscosity (mPa s 23C) 80000 Part B Viscosity (mPa s 23C) 25 Mixed System Viscosity (mPa s 23C) 5000 Mix Ratio (Weight) 12.78:1 Mix Ratio (Volume) 5.58:1 Usable Life (20C) 120 mins Gel Time (23C) 7 hours Cure Time (23 C) 24 hours Cure Time (60 C) 4 hours Cure Time (100 C) 1 hour Colour Part A - Resin Black Colour Part B - Hardener Black Storage Conditions Dry Conditions: Above 15C, Below 30C Shelf Life 24 Months (bulk) 12 months (resin pack) Exotherm (Measured on 100ml sample in a cylinder of < 35C diameter 49.4mm 23C) Shrinkage < 1% Electrolube, A division of H K Wentworth, Kingsbury Park, Midland Road, Swadlincote, Derbyshire, DE11 0AN Tel: +44(0) 1283-222111 Fax: +44(0) 1283-550177 www.electrolube.com BS EN ISO 9001:2000 Certificate No. FM 32082 Page 1 of 3 Cured System: Thermal Conductivity (W/mK) 1.1 Cured Density (g/ml) 1.95 Temperature Range (C) -40 to +130 Max Temperature Range (Short Term C / 30 Mins) +150 (Application and Geometry Dependent) Dielectric Strength (kV/mm) 10 15 Volume Resistivity (ohm-cm) 10 Shore Hardness D90 Colour (Mixed System) Black Flame Retardency Yes Tensile Strength (MPa) 60 Compressive Strength (MPa) 120 Deflection Temperature (C) 60 Coefficient of Expansion (ppm/C) 30 Loss Tangent 50 Hz 0.05 Permittivity 50 Hz 6.00 Comparative Tracking Index >850 Volts Water Absorption (9.7mm thick disk, 51mm diameter) < 0.5% / < 1% 10 days 20C / 1 hour 100C Elongation At Break 0.4% 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. Bulk Mixing When mixing, care must be taken to avoid the introduction of excessive amounts of air. Automatic mixing equipment is available which will not only mix both the resin and hardener accurately in the correct ratio but do this without introducing air. Containers of Part A (Resin) and Part B (Hardener) should be kept sealed at all times when not in use to prevent the ingress of moisture. Bulk material must be thoroughly mixed before use. Incomplete mixing will result in erratic or partial curing.
