In the anodising process, one step in especially takes a lot of time: hot sealing. But this no longer has to be the case. With the FastsealAL process from Alufinish, you can save a lot of time in the anodising process. Nowadays 2 min./µm are already possible by using suitable hot sealing additives while still maintaining acceptable sealing values. With the new FastsealAL process (Alfiseal 938) you can achieve a further time advantage. Anodised surfaces can be pretreated with this process with only half the sealing time.
The process also offers other advantages:
- Alfiseal 938 is metal-free and requires no subsequent rinsing of the surface
- Reduction of hot sealing time to up to 1 min./µm, even with coloured surfaces
- Good sealing quality despite shorter sealing times
- Prolongation of bath life due to “never-dump” operation, easy filtration
- Seal additive can be analysed for quality-compliant application
- At 2 minutes/µm hot sealing time a Qualanod – compliant operation is possible
