Wipe Procedure

  1. The mold surface must be thoroughly cleaned of all residues of waxes, release agents and sealers. We recommend Chemlease® Mold Cleaner EZ. (please ask your Chem-Trend Sales Representative for recommendations).
  2. Saturate a clean 100% cotton cloth with Chemlease® Sealer 2697 (not dripping wet) and apply in a thin even film. Only work on an area of ​​0.6 m² at a time.
  3. A sufficiently thin layer can be recognized by the sheen, no "running" should be visible. Under normal conditions, this film dries in 60 seconds.
  4. If a damp film is still visible after 1 minute, the film was applied too thick and may cause streaks / streaks on the mold. To solve this problem on the affected mold area, remove the sealer film by rubbing with a dry cotton cloth. Then apply a very thin, fresh sealer film with a lightly soaked cotton cloth and immediately rub off with a dry cotton cloth in circular movements to remove the streaks/streaks that have formed. Then apply a fresh thin layer of sealer as described above (step 3).
  5. Repeat the above steps until the entire mold surface is finished.
  6. Let this layer dry for 15 minutes.
  7. Apply a second coat of Chemlease® Sealer 2697 as described above. For a new mold or very difficult to demould parts, Apply two more layers to the components so that total of 4 coats are applied. (Please wait 15 minutes between each shift).
  8. Allow approximately 30 minutes to cure before applying the release agent.

Spray Method

  1. The mold surface must be thoroughly cleaned of all residues of waxes, release agents and sealers. We recommend Chemlease® Mold Cleaner EZ. (please ask your Chem-Trend sales representative for recommendations).
  2. When spraying, use a clean hand spray gun or clean, dry compressed air spray system. It is important that all containers and spray accessories are thoroughly cleaned and dry. Hold the spray gun 10-15 inches from the mold and spray a thin, even film. The film must not run or drip (avoid overdosing).
  3. In order to completely coat the mold surface, spray on a second very thin coat crosswise (0° / 90°). With spray application, there is no waiting time between coats.
  4. For a new mold or components that are very difficult to demould, spray on two more thin coats as described (a total of 4 coats).
  5. Allow approximately 30 minutes to cure after the last coat before applying the release agent.

Important: The recommended number of mold coats and drying and curing times are general guidelines based on a wide range of applications and demolding conditions. Under special conditions such as extreme shape geometries or low humidity, longer curing times or a higher number of coats than indicated may be necessary.
