Loctite 3843 Matte Black resin contains a chemical component that may leach out during cleaning, often appearing as a white residue or surface haze on the printed part. This can negatively impact the part's surface finish and overall appearance.
Recommended Post-Processing Procedure
1.Use Clean IPA
- Ensure that the Isopropyl Alcohol (IPA) used in the B9Clean unit is as clean and fresh as possible.
- Contaminated or saturated IPA can increase chemical leeching from the part.
- The longer a part sits in IPA, the more likely it is to experience surface leeching.
- Recommended clean cycle: 10 minutes max. Depending on part size and complexity, less time may be more effective.
- As soon as the part is removed from the clean unit, blow off residual IPA using clean compressed air.
- This step is critical to stop ongoing chemical interaction with IPA on the surface.
- If resin remains on the part, repeat steps 2 and 3 using shorter cleaning cycles (1–2 minutes max).
- Continue until all visible resin is removed.
5. Remove Surface Whitening (if visible)
- If white residue remains, place the part in a container of clean IPA and then into an ultrasonic cleaner.
- Run for 30–60 seconds, then remove and dry with compressed air.
- This helps dislodge any leached compound clinging to the surface.
- Wait 10–15 minutes between repeated cleaning cycles.
- This allows the part to fully dry and any absorbed IPA to evaporate from within the material.
Important Notes
- These steps do not guarantee a perfectly clean surface, but they will greatly reduce whitening and other finish-related imperfections.
- Consistent cleaning practices and fresh IPA are key to maintaining optimal surface quality.
