Conathane EN-13 Flexible Polyurethane Encapsulant, 1 Gallon

Description

Conathane EN-13 is a two-part, room-temperature-curing polyurethane resin system for potting, encapsulating, and coating strain-sensitive electronic assemblies. The unfilled amber system starts at low viscosity for penetration into fine windings, then cures to a tough and flexible material that can protect modules, connectors, and electrical units over a wide service range.

Conathane EN-13 Benefits

• Low initial viscosity helps resin flow around windings, terminals, and tight connector geometry.
• Flexible cured properties reduce stress on parts that can be damaged by harder encapsulants.
• Room-temperature cure supports bench work without a dedicated oven cycle.
• Transparent cured material can be cut for component access during repair or failure review.
• Good water resistance and electrical properties support demanding electronic protection work.

This 1 gallon listing is useful for repair benches, small production cells, and engineering builds that need a flexible polyurethane rather than a filled epoxy or rigid casting compound. It can also be used in conformal coating work when the application method and thickness are validated.

Where Conathane EN-13 Fits

• Potting strain-sensitive modules and connector backshells.
• Encapsulating coils, windings, and small electrical units.
• Protecting assemblies that see high and low temperature cycling.
• Repairing castings by adding more liquid system after component service.
• Spray, brush, or casting workflows after process testing.

Surface Preparation and Use

Keep parts clean, dry, and at a stable shop temperature before mixing. Remove flux residue, oil, loose insulation, and dust so the resin can wet the part. Meter and mix the two components thoroughly, then degas when the assembly geometry makes trapped air likely.

For sensitive electronics, run a small trial to confirm cure, heat rise, and rework access. Document mix ratio, batch size, and cure time so production results stay repeatable.

Technical Details and Documentation

Published CONAP data identifies this material as an unfilled polyurethane system for potting and encapsulating devices operating from -65 C to 130 C, with Part A viscosity around 1700 cP and Part B around 900 cP at 25 C. Review ELANTAS resources at ELANTAS before production use.
