DIRECTIONS FOR USE 1. Surface Preparation ● Surface to be coated must be dry and free on contaminants such as oil or chemical residues. 2. Mixing/Dilution ● Thoroughly mix LOCTITE EDAG 440 AS E&C before dilution. Normally, the product is diluted with MEK. ● Recommended dilution ratio(s) as follows: By Volume: 1 part product to 1 part solvent By Weight: 5 part(s) product to 2 part(s) solvent ● Complicated parts, such as those molded from solvent sensitive plastics (ABS, Polystyrene and Polycarbonate), are very prone to stress cracking. In such cases, replacing about 15% of the MEK with Isobutanol or Diaceton Alcohol (DAA) provides a suitable alternative. 3. Application ● LOCTITE EDAG 440 AS 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 50 to 75 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. 4. Drying ● LOCTITE EDAG 440 AS E&C dries to touch in about 5 minutes; to handle in approximately 20 minutes, depending on ambient temperature, coating thickness and diluent. ● Best coating properties will be achieved after 4 to 16 hours air drying, depending on coating thickness and ambient temperatures. ● Forced drying at 60 to 70 oC for 20 to 30 minutes is possible 5. Cleanup ● For high volume production where masks are used to prevent coating certain areas, the masks can be cleaned with esters (butylacetate, ethylacetate) or ketones (MIBK, MEK) solvents. ● Spray or mixing equipment may be cleaned with the same solvents.
