IFAM confirms
The positive results known from practice which the additive has already achieved have been scientifically verified in a case study by the Fraunhofer Institute for Manufacturing Technology and Advanced Materials (IFAM) in Bremen.
In particular, investigations were performed and evaluated for the sensitive area of surface preparation for the application of corrosion protection coatings. For this purpose, test samples were prepared at the site of the user Eggersmann Anlagenbau (EAB), Bad Oeynhausen, in accordance with the instructions by Fraunhofer IFAM and then examined.
The test samples were steel metal sheets that were first cleaned and were completely degreased. Afterwards these samples were contaminated in a defined manner with oils and greases which are normally used in the production process at EAB. Then the test samples were clean blasted on the existing blasting system (from Konrad Rump) with the blasting medium AMASTEEL S330 and PantaTec ULTIMATE and were degreased.
After the subsequent testing, among other things using x-ray photoelectron spectroscopy XPS, the steel surfaces peened with ULTIMATE were classified as suitable for coating with finishing systems. The subsequent salt spray tests for the coated surfaces have verified this.
Among other things, the following investigations were carried out at IFAM:
- Measurement of the achieved surface roughness
- Measurement of the electrical conductivity by Bresle chloride test
- Measurement of XPS in atom-percentage
Examinations revealed no impermissible residues on the metal surface. The surface was classified as fully capable of coating / adhesion comparable to conventionally blasted and degreased surfaces.
