CoolTherm™ EP-636 Epoxy Encapsulant Where to Buy
LORD CoolTherm™ EP-636 epoxy encapsulant is a two-component system specifically designed for high temperature applications. CoolTherm EP-636 encapsulant is recommended for encapsulation of electric motor stator assemblies used on downhole oil pumps.
Shelf life is one year for CoolTherm EP-636 resin and two years for CoolTherm EP-636 hardener from date of manufacture when stored at 25°C in original, unopened container. CoolTherm EP-636 resin must be periodically rotated within its container to maintain maximum shelf life. Settling will occur if not mixed.
CoolTherm EP-636 hardener may crystallize during shipment or storage. If crystals appear, gently warm hardener at 50-65°C to melt crystals before mixing with resin.
Features and Benefits
High Temperature Electrical Performance – maintains electrical insulation stability at extremely high temperatures.
Environmentally Resistant – provides protection of electrical devices exposed to harsh environmental conditions.
Durable – exhibits very low weight loss over extended periods at elevated temperatures.
