Product Information
CoolTherm® EP-2000 encapsulant is a two-component, low viscosity epoxy system designed for encapsulation of motor stators, transformer coils, and other devices with small-diameter, tightly-packed windings. CoolTherm EP-2000 encapsulant provides high-temperature stability combined with excellent electrical insulation.
Shelf Life
Shelf life of each component is nine months when stored at 25°C in original, unopened container. CoolTherm EP-2000 resin and hardener must be periodically rotated within original containers to maintain maximum shelf life. Settling will occur. Products must be mixed as directed before use. To achieve properties and minimize hard-packed settling of fillers during storage, follow the general considerations and storage tips recommended in the Parker LORD Technical Tip – “Mixing of CoolTherm EP-3500 and EP-2000 Potting Materials”.
Features and Benefits
Excellent Heat Dissipation – provides lower motor end winding temperatures during high-power operation.
Low Viscosity – provides fine-particle filler and low viscosity; self-levels to fill voids in motor stators/rotors, transformer coils and other electrical devices.
Durable– cured material resists cracking during multiple thermal cycles from sub-zero temperatures to 200°C.
UL Rated – approved for use in PDG-H2, Table V insulation constructions (Class H – 180°C).
