LORD Thermoset EL-636是专门为高温应用而设计的双组份体系，推荐用于井下油泵的电机定子组件。
LORD Thermoset EL-636 epoxy encapsulant is a two-component system specifi cally designed for high temperature applications. Thermoset EL-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.
Mixing – Thoroughly stir each component prior to mixing together. Mix Thermoset EL-636 resin with Thermoset EL-636 hardener at a 100 parts resin to 1 part hardener, by weight, until uniform in color. Automatic meter/mix/dispense equipment may be used for high volume production.
Applications involving large mass castings may require a mix ratio of 100 part resin to 0.75 parts hardener, by weight. Tests should be conducted to determine the optimal mix ratio.
Unless a closed-chamber mechanical mixer is used, air will be introduced into the encapsulant system either during mixing or when catalyzing the mixture. Electrical properties of the epoxy encapsulant are best when air bubbles and voids are minimized. Therefore, in extremely high voltage or other critical applications, vacuuming may be appropriate.
Applying – Apply epoxy encapsulant using handheld cartridges or automatic meter/mix/dispense equipment.
Curing – Allow encapsulant to cure for 16-24 hours at 50-65°C, followed by 2 hours each at 95°C, 150°C and 205°C. In special circumstances where conditions do not permit the use of the typical cure schedule, alternate curing cycles may be determined by consultation with LORD.
Cleanup – Disposable containers and utensils are recommended when working with epoxies. However, when disposable materials are impractical, uncured encapsulant can be removed by cleaning equipment with solvent. Solvent-cleaned utensils should be thoroughly dried before reuse; any remaining solvent can contaminate the next mixture.

Shelf life is one year for Thermoset EL-636 resin and two years for Thermoset EL-636 hardener from date of manufacture when stored at 25°C in original, unopened container. Thermoset EL-636 resin must be periodically rotated within its container to maintain maximum shelf life. Settling will occur if not mixed.
Thermoset EL-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.
