Conathane EN-11 Part B Curative 1 Gallon Container

Description

Conathane EN-11 Part B Curative is the curative side of an ELANTAS polyurethane encapsulating system for electrical and electronic assemblies that need flexible protection after potting, molding, or casting. This 1 gallon container supports production teams working with compatible Conathane Part A materials, including EN-4 Part A, where controlled mixing, degassing, and cure handling are part of the process. ELANTAS lists the system as a two-part liquid polyurethane for molding, potting, casting, and encapsulation, with use cases that include connectors, cables, wire wound devices, printed circuitry, and other strain-sensitive electronic assemblies.

Conathane EN-11 Mixing And Handling Notes

Use this Part B curative only with the matching Conathane resin system specified for the job. Source data calls out a 100/55 mix ratio by weight for the EN-11 system, with Part A viscosity around 8,500 cP, Part B viscosity around 4,000 cP, and an initial mixed viscosity around 5,750 cP at 25 C. For best results, mix at 25 C to 40 C using clean metal, plastic, or glass tools, then degas the mixed material before pouring. Avoid moisture introduction during processing because it can affect polyurethane cure quality and final electrical protection.

Conathane EN-11 Application Fit

The cured system is built for flexible protection rather than rigid structural bonding. ELANTAS lists benefits that include hydrolytic stability, high flexibility, and use in severe environmental exposure. The material data also reports Shore A hardness around 60, tensile strength around 750 psi, and elongation around 350 percent, which helps explain its fit for potted components that may see movement, temperature cycling, or assembly stress. Typical cure schedules include elevated-temperature options such as 24 hours at 60 C or 16 hours at 80 C.

Ordering Support For Potting Work

Pair this curative with the correct Part A, approved containers, and a documented mix process before releasing it to production.
