Description

LORD Thermoset EP-937 encapsulant is a black, onecomponent epoxy specifi cally designed to meet the needs of coating semiconductor devices on printed circuit boards.

Features and Benefits

Convenient – requires no mixing; provides excellent shelf life stability; prepared under vacuum and contains no entrapped air or solvents.

Environmentally Resistant – provides excellent resistance to thermal shock and moisture.

Fast Cure – quickly cures at 150°C with a void-free, smooth surface.

Outstanding Adhesion – offers a fast elevated temperature cure for outstanding adhesion to a variety of materials.

Application

Applying – Before use with dispensing equipment, allow encapsulant to be warmed to room temperature (ideally 20-25°C). Thaw encapsulant by placing the syringe in a vertical (upright) position with dispense tip facing downward in an ambient environment. Consult handling instructions** for specifi c guidelines.

Apply encapsulant by pneumatic-powered syringe or by coating with a disposable applicator. Do not use for coating masses larger than 25 grams.

**Handling instructions are available on LORD.com.

Typical Properties*

Curing – Allow encapsulant to cure for 20 minutes at 150°C in an elevated temperature circulating air oven or on a hot plate.

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.
