Shelf Life Details The shelf life of CE-1155, Part A and Part B is 15 months from date of manufacture when stored in the original, unopened containers at the above recommended temperatures.;CONATHANE® CE-1155 should be stored at temperatures of 65°-85°F in tightly closed containers. If containers are opened and the contents only partially used, the container should be flushed with dry nitrogen (see CONAP® Dri-Purge) or dry air before being re-sealed., Store at 20 – 30°C / 68 – 85°F in a dry controlled environment out of direct sunlight. This material should be suitable for use stored under these conditions in the original sealed containers for twelve (12) months from the date of shipment.

Best Practices for Elantas (Altana) Conathane CE-1155
-
Surface Preparation
Cleanliness of the substrate is a major factor in promoting adhesion and preventing under-film corrosion. Assemblies must be clean, oil-free, and dry.
-
Application
CE-1155 can be applied by spraying, dipping, or brushing. If viscosity reduction is desired, dilutions of 10 – 20% by weight with the CONAP® S-8 Solvent are recommended for most applications. For some spray applications, dilutions up to 1:1 by volume may be required to avoid cobwebbing.
A minimum of two coats of CE-1155 is recommended for optimal protection. A total cured film thickness of 2 ± 1 mils is recommended. CE-1155 may be recoated after the previous film is tack-free.
-
Curing
Curing of the film is dependent upon the evaporation of the solvents and subsequent reaction of the polymer.
