Description
EN-1556 potting compound is a black, two-component polyurethane system for cable breakouts, watertight electrical connectors, cables, and cable end seals. This ELANTAS material is an unfilled, room-temperature-curing, 100% solids system with a cartridge-friendly 3:1 volumetric mix that also serves casting and molding jobs needing abrasion resistance.
EN-1556 Potting Compound Benefits
- 3:1 volumetric mix supports cartridge work and meter-mix dispensing.
- Two-component polyurethane chemistry stands up well to hydrolytic exposure and thermal shock.
- Black-curing system helps hide filled cavities and molded electrical assemblies.
- Unfilled 100% solids design fits potting, casting, and molding work.
- Electrical and mechanical performance makes it useful in demanding service conditions.
This system is a fit for electrical potting teams that need a flexible encapsulant instead of a brittle casting resin. The manufacturer lists hand-mix bench casting, meter-mix bench potting, and meter-mix vacuum potting as standard application methods, with ordinary casting or injection molding techniques also supported.
Common Applications for EN-1556 Potting Compound
- Cable breakouts and cable end seals.
- Watertight electrical connectors and cable molding.
- Protective potting around wire bundles and electronic housings.
- Molded mechanical parts that need abrasion resistance.
- Lining service parts such as pumps, chutes, and conveyors.
Compatible Materials and Processing Notes
- Use with EN-1556 Part A and Part B mixed 100:33 by weight or 100:33 by volume.
- Components can be preheated to 60 C when lower viscosity is needed.
- Hand-mixed batches should be degassed above 27 in. Hg vacuum before use.
- Adhesion primers are available for metal, neoprene, and PVC applications.
