Best Practices for Elantas (Altana) Conathane EN-21

*See Terms of Use Below

Mixing

Mix the two components together thoroughly at room temperature in metal, plastic, or glass containers, using a metal spatula. DO NOT use paper containers or wooden sticks. Any moisture introduced into the system will cause bubbling and/or foaming during curing.

Pour into dry preheated units. Best results are generally obtained when the unit is at least 10°C warmer than the mixed material. Pour down the side of the unit to be potted to avoid air entrapment.

If the potted device is to be heat cured, it is best to allow the device to sit at room temperature for 1-2 hours to permit air bubbles, entrapped during pouring, to dissipate.

When containers are opened and the contents only partially used, be certain to flush them with dry nitrogen or CONAP® Dri-Purge (Request Technical Bulletin AC-105) to prevent moisture contamination and subsequent waste of material.
Deairing/Degassing

If void-free castings are required for the particular application, degas the mixed system at 1-5 mm of mercury vacuum. Allow froth to rise and collapse

continue vacuum for 2-5 minutes. Containers should generally have twice the volume of mixed material to allow for frothing.
