Application Procedure

  1. XP-400 should be stirred prior to usage and periodically if not used for extended periods of time.
  2. Chemically and/or mechanically clean the area of the part to be masked. The area to be masked must be free of all dirt, oil or other contaminants. Cleaning is the most critical aspect of the masking procedure.
  3. Apply XP-400 to the area to be masked by dipping or brushing. For reducing XP-400, use XP-400 Reducer only.
  4. Two or Three coats are recommended depending upon the type of plating/chemical solution and/or length of processing time in solution. Allow at least a one-hour dry time between coats. A longer dry time between coats will improve the performance of the product. This factor is highly dependent on the severity of the plating cycle. Faster drying of XP-400 can be accomplished by force drying for 15 minutes in an oven. Temperatures must not exceed 140 °F and times over 15 minutes. Dry time will vary according to relative humidity. NOTE: Make sure XP-400 has lost all solvent odor before force drying or applying additional coats.
  5. For extra long cycles, 3 coats are recommended. If the area to be masked is highly polished, refer to the “Masking Polished or Smooth Surfaces” technical data page for improved adhesion.
  6. XP-400 can normally be peeled from the part after processing. For mass stripping or removal from recessed areas, use XP-400 REDUCER or MICCROSTRIP A
