CONATHANE CE-1155 is a two-component, solvent-based polyurethane printed circuit board coating designed for use in adverse environments. CONATHANE CE-1155 provides outstanding resistance to moisture and good abrasion resistance.

The cured film is hard and tough and has excellent adhesion to phenolic and epoxy-glass laminates. When tested over printed circuit patterns, excellent results are obtained with 1.5 mil films. Defective components can be replaced in coated areas using ordinary repair procedures without degradation or discoloration. Spot re-coating can then be accomplished.

CONATHANE CE-1155 may be applied by spray, dip, or brush techniques and will cure at room or elevated temperatures. The cured film is suitable for continuous operation up to 130°C. The system contains a fluorescent dye to aid inspection under ultraviolet light.
