Shelf Life Details Conathane EN-1554, two-component units, and the recommended primers have a shelf life of 15 months from the date of manufacture when stored in the original, unopened containers below 80ºF. CONATHANE EN-1554, Part A is a reactive isocyanate prepolymer and will react with atmospheric moisture. If containers are opened and the contents only partially used, the containers should be flushed with dry nitrogen (see CONAP® Dri-Purge) or dry air before being resealed.

Best Practices for Elantas (Altana) Conathane EN-1554
-
Surface Preparation
To obtain satisfactory adhesion, CONATHANE EN-1554 should be applied only to dry surfaces that are free of dirt, grease, oil, and mold release agents, and have been properly primed with primers recommended herein: METALS - Clean and treat as recommended in Bulletin A-143. Apply CONAP AD-1146 primer and air dry for 1 hour, then bake for 2 hours at 160ºF-180ºF. Apply CONATHANE EN-1554 and cure as recommended.
NEOPRENE - Wash neoprene thoroughly with MEK to remove dirt, oil, and grease. Abrade with a suitable abrasive and clean loose particles with a clean, dry brush. Apply CONAP PR-1167 primer and air dry for 1-2 hours or until tack-free. See Bulletin A-144 for complete details. Apply CONATHANE EN-1554 and cure as recommended.
POLYVINYL CHLORIDE - Make the surface tacky with MEK and apply a thin, uniform coat of CONAP AD-1161 primer to the tackfied surface and air dry for 30 minutes. See bulletin A- 117 for complete details. Apply CONATHANE EN-1554 and cure as recommended.
-
Mixing
The two components should be mixed together thoroughly at 77ºF to 180ºF depending on the viscosity and pot life desired. Containers and stirrers should be metal or glass. DO NOT USE WOOD.
-
Deairing/Degassing
Degas the mixed system until foaming subsides (approximately 5 minutes at less than 5 mm of mercury). Large quantities may require slightly longer periods of degassing. Containers should be large enough to allow for frothing during degassing. If the material is to be transferred to a cartridge, it is suggested that the material be flowed down the side of the cartridge carefully so as not to entrap air.
For best results, it is suggested that both Part A and Part B be heated to 140ºF and degassed separately for about 10 minutes at 1-5 mm of mercury. The two components can then be mixed together thoroughly at this temperature or allowed to cool to room temperature before combining. After having mixed the two components together, they should be degassed again at 1-5 mm of mercury.
-
Clean-Up
Equipment should be cleaned immediately after use with methyl ethyl ketone or a CONAP® solvent.
