Full Product Description

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.

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.

Shelf Life/Storage:
Shelf life is one year for CoolTherm EP-636 resin and two years for CoolTherm EP-636 hardener 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.
