Alufinish is pleased to announce the approval of two innovative pre-treatment systems for aluminium surface treatment in the anodising sector. The certificates for Alfinox 510 (ENSAVAL process) and Alfiseal 1960 were officially awarded by the Qualanod Quality Association on 17 June 2025. This means that both products can now also be used in Qualanod member companies.
Both products, which represent an ideal combination of anodising additive and medium-temperature sealing, offer significant energy savings for the anodising process. On the one hand, cooling energy is saved by working at higher anodising bath temperatures and, on the other hand, heating energy is saved by sealing at lower temperatures.
The test results, which were recorded from May 2023, met all the criteria of the Qualanod specification. An important part of the test was the one-year outdoor exposure of the samples, which then took place from September 2023 in the challenging coastal regions of Hoek van Holland and Genoa. The final assessment and evaluation of the samples in spring 2025 confirmed the outstanding quality and performance of the two pre-treatment processes. For final approval by Qualanod, the samples will be exposed to weathering for a total of 3 years.
The Qualanod approval underlines Alufinish’s commitment to innovative and sustainable solutions in the field of aluminium surface treatment. The new systems offer our customers the opportunity to make their production processes more energy-efficient while ensuring the highest quality standards.
