UR5118RP250G Electrolube

Page 1 UR5118 Polyurethane Resin UR5118 is an ultra-high performance resin system, which offers very high protection in a range of harsh environments. It has low moisture sensitivity during cure and its low viscosity allows the resin to flow around complex geometries. High toughness and tear resistance maintains flexibility down to -60C Low water absorption, high resistance to sea water offers enhanced protection under harsh conditions Excellent oxidation resistance and very good adhesion to most substrates Very low viscosity ideal for potting complex geometries and units with small spaces RoHS Compliant (2015/863/EU): Yes Approvals UL Approval: No Typical Properties Liquid Properties: Base Material Polyurethane Density Part A - Resin (g/ml) 0.92 Density Part B - Hardener (g/ml) 1.22 Part A Viscosity (mPa s 23C) 3390 Part A Viscosity (mPa s 40C) 1600 Part A Viscosity (mPa s 60C) 780 Part B Viscosity (mPa s 23C) 150 Mixed System Viscosity (mPa s 23C) 2300 Mixed System Viscosity (mPa s 40C) 1630 Mixed System Viscosity (mPa s 60C) 860 Mix Ratio (Weight) 2.77:1 Mix Ratio (Volume) 3.66:1 Usable Life (20C)* 25-30 mins Usable Life (40C)* 12-17 mins Usable Life (60C)* 7-12 mins Gel Time (20C)* 40-45 mins Gel Time (40C)* 30-35 mins Gel Time (60C)* 12-17 mins Cure Time (23 C)* 36 hours Colour Part A - Resin Black Colour Part B - Hardener Brown Storage Conditions Dry Conditions: Above 15C, Below 35C Shelf Life 12 months Page 2 Exotherm < 35C (Measured on 100ml sample in a cylinder of diameter 49.4mm 23C) Shrinkage < 1% * Dependent upon quantity and temperature these figures are typical of 150g mass.

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.
