Application Procedure

  1. Chemically and / or mechanically clean the area of the part to be masked. The area to be masked must be free of all dirt, grease, oil or other contaminants. Cleaning is the most critical aspect of the masking process.
  2. Apply MiccroShield to the area to be masked by dipping, brushing, or spraying. Appropriate dilution of MiccroShield is required for spraying. For reducing MiccroShield use MiccroShield Reducer only!
  3. Apply a minimum of 2 successive coats of MiccroShield to the area to be masked, allowing a minimum of 30 minutes air-dry time between coats and overnight air-dry time after final coat before introduction into solution. Faster drying of MiccroShield can be accomplished by force-drying for 15 minutes in an oven not exceeding 140° F, or over a hot plate not exceeding 140° F. Drying time will vary depending on relative humidity. Make sure MiccroShield has lost all solvent odor before force drying or applying additional coats. Drying over a hot plate is preferable to oven drying.
  4. For extra long cycles, 3 coats are recommended. If area to be masked is highly polished, see back page for additional application procedures.
  5. MiccroShield can be removed using MiccroStrip B or MiccroStrip A. MiccroShield Reducer is also effective but somewhat slower.
  6. Replace evaporated solvent with MiccroShield Reducer ONLY!

For Masking polished Silver and Copper based alloys

After final polishing and cleaning (no water constrictions, etc.), the following process is suggested:

  1. Chromate treat the part (commercial chromate product), exposure time 30 to 60 seconds depending on solution pH and concentrate. (NOTE: No visible etch or darkening should appear on critical polished surfaces.)
  2. Clean water rinse the part at ambient temperature.
  3. Force dry the part using clean, oil free air.
  4. Dilute MiccroShield 50/50 with MiccroShield Reducer.
  5. Apply "thinned" MiccroShield to all areas of the part being stopped off.
  6. Air dry part with "thinned" MiccroShield until the solvent odor is gone.
  7. Bake part with "thinned" MiccroShield for 10-15 minutes in a circulating oven or over a hot plate not to exceed 150° F.
  8. Cool part to room temperature.
  9. Apply 1st coat of MiccroShield over all areas of the part that were primed with the "thinned" MiccroShield and let air dry for 20-30 minutes.
  10. Apply a 2nd coat of MiccroShield and let air dry for 20-30 minutes.
  11. Bake part for 10-15 minutes in a circulating oven or over a hot plate not to exceed 150° F.
  12. Cool part and prepare surface for the required electroplate.
