Conathane CE-1164

CONATHANE® CE-1164 is a single-component, air drying, room temperature curing, polyurethane conformal coating which meets the requirements of MIL-I-46058C for Type UR coatings and appears on the Qualified Products List (QPL).

CE-1164 is a solvent-based coating designed for thin-film applications on electronic components and printed circuitry. It was developed specifically to provide the ultimate in humidity resistance and hydrolytic stability, while retaining excellent flexibility to prevent fracturing of fragile components during thermal cycling.

Cured films maintain excellent adhesion to phenolic and epoxy -glass laminates even in adverse environmental conditions. A tracer dye has been incorporated to aid inspection under ultraviolet light.

CONATHANE® CE-1164 Application Information

CONATHANE® CE-1164 is a high-performance conformal coating specifically designed as an electrical insulating coating for printed circuitry and components. The ultimate performance of the 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. For specific recommendations, please request Technical Bulletin C-115.

CE-1164 may be applied by spraying, dipping, or brushing. If viscosity reduction is desired, dilutions of 10-20% by weight with CONAP® S-8 solvent are recommended for most applications. It should be noted that CE-1164 reacts with moisture in the air, and dip tanks should be covered and blanketed with dry air or nitrogen when not in use to prevent waste of material in the tank.

Two coats are recommended for optimum protection. A total cured film thickness of 2 ± 1 mil is recommended. CE-1164 may be re-coated, if desired, after the previous film is tack-free.

Cure

Curing of the film is dependent upon evaporation of solvents and subsequent reaction of the polymer with moisture in the air to effect its cure. The coating will dry tack-free in approximately 20-30 minutes and will cure in 24 hours at room temperature. Optimum physical and electrical properties require a post-cure of 5 to 7 days at room temperature. (An alternate cure of 3 hours at 60°C plus 2-3 days at room temperature may also be used). NOTE: CE-1164 should not be used where humidity conditions are less than 30%. CONAP® S-8 Solvent is recommended for cleaning equipment and for removing uncured CE-1164

Storage And Handling

Maintain containers at temperatures of 65°-85°F and keep securely closed when not in use; moisture may cause polymerization. To extend shelf life once opened, containers should be flushed with nitrogen (see CONAP® Dri-Purge) each time they are opened unless the contents are used within one day.

CONATHANE® CE-1164 has a minimum shelf life of 15 months from date of manufacture when stored in original unopened containers at 65°-85°F.

Caution

CE-1164 contains traces of monomeric isocyanate. Use only in well-ventilated areas. Adequate ventilation should be provided during and immediately after application. Avoid breathing of vapors or spray. Prevent skin contact. If contact occurs, wash with soap and water.

Material is flammable. Do not use in presence of open flames or sparks.
