Product Description
BONDERITE M-PT 100NC is a chromium-free sealing rinse for conversion-coated aluminum surfaces. Applied after the conversion-coating step, it promotes paint adhesion and corrosion resistance before final finishing. The treatment can be used by spray or immersion, with short application windows matched to each process: 15 to 60 seconds for spray and 30 seconds to 2 minutes for immersion. Operation is supported from ambient temperature to 120 deg F, with a working pH of 3.75 +/- 0.25. The product serves as a focused metal post-treatment rather than a primary conversion coating.
Key features
- Chromium-free seal rinse: Post-treats conversion-coated aluminum before painting.
- Process flexibility: Supports spray and immersion application methods.
- Short treatment windows: Uses seconds-to-minutes application times at ambient to 120 deg F.
Applications
Applications include post-treatment of conversion-coated aluminum by spray or immersion before painting.
