Applications area of CONATHANE® CE-1155
CONATHANE® CE-1155 provides an excellent electrical and moisture barrier for thin film applications on components and printed circuit boards.
Application / Curing Schedule
Performance of the Elantas CONATHANE® CE-1155 cured film is dependent on process controls used in application of the coating. Cleanliness of the substrate is a major factor in promoting adhesion and preventing under-film corrosion. Assemblies must be clean, oil-free, and dry.
CONATHANE® 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 CONATHANE® 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 of the film is dependent upon the evaporation of the solvents and subsequent reaction of the polymer. Use the following estimates for tack-free and cure times:
| Temperature | Tack-free Time | Cure Time |
| 25°C (77°F) | 5 – 6 hours | 5 – 7 days |
| 60°C (140°F) | 30 – 45 minutes | 3 hours |
| 100°C (212°F) | 10 – 15 minutes | 1 hour |
