  • Best Practices for Elantas (Altana) Conathane CE-1155-35

    *See Terms of Use Below

    1. Application

      CONATHANE® CE-1155-35 is a high-performance conformal coating based on raw materials of the highest purity. The ultimate performance of the cured coating on an assembly is dependent on process controls used in application of the coating.

      Specific substrates to be used in production should be thoroughly evaluated. For example: there may be differences in performance on G-10, G-1,or other laminates. Cleanliness of the substrates is a major factor in promoting adhesion and preventing under-film corrosion. Boards MUST be clean, oil-free, and dry. Request Technical Bulletin C-115 for specific cleaning recommendations prior to coating.

      Because CE-1155-35 is a solvent-based system, it is not recommended that more than 2 to 2.5 mils of wet film thickness be applied during any one application. This will prevent the possibility of solvent entrapment. If more than one coat is desired, allow 2 hours at room temperature or 2 hour at 60°C before re-coating.

      CE-1155-35 can be applied by spraying, dipping, or brushing and may be thinned with CONAP® S-8 solvent to lower the viscosity or to adjust film thickness.
