DIRECTIONS FOR USE Surface Preparation ● Surfaces to be coated must be clean, dry and free of dust. Mixing/Dilution ● Thoroughly mix in a paint shaker before use. ● LOCTITE EDAG 550 E&C is a slow/soft settling material. Mixing time can be substantially reduced when compared to conventional nickel coating. ● For proper dilution, use a ratio of 1 : 0.8, product : solvent by volume. Application ● LOCTITE EDAG 550 E&C should be applied by spray using conventional propeller agitated pressure pot spray systems. ● Small prototype runs may be sprayed with well-mixed product, using suction cup spray equipment. ● A nominal 51 to 63.6 μm dry coating thickness is recommended for good shielding performance. However, a thinner coating may be acceptable, depending on the shielding requirements of the device being protected. ● Avoid dry spraying for maximum adhesion and conductivity. ● During humid days, the addition of no more than 6 fluid ounces per gallon of diacetone alcohol or butyl alcohol to LOCTITE EDAG 550 E&C will eliminate blushing. The blushing is characterized by a white tint to the dried surface. Drying ● LOCTITE EDAG 550 E&C dries to touch in about 5 minutes; to handle in approximately 30 minutes, depending on ambient temperature and coating thickness. ● The product may be force dried beginning with a 20-minute flash-off, then 30 minutes at 60° to 71°C.
