NICKEL-FREE LOW TEMPERATURE SEAL

NICKEL-FREE LOW TEMPERATURE SEAL

FINALLY NICKEL-FREE LOW TEMPERATURE SEAL WITH MEDIUM TEMPERATURE AGEING  OFFICIALLY PRESENTED AT ALUMINIUM TWO THOUSAND CONGRESS IN FLORENCE, 12-16 MAY 2015 The nickel-free HARDWALL EHR low temperature sealing process allows sealing of anodic oxide layers on aluminium and its alloys to be carried out at room temperature. The result is a perfect quality seal suitable for outdoor corrosion resistance including industrial and marine environments. HARDWALL EHR is an ecological process completely free from nickel and other toxic compounds. HARDWALL EHR requires an ageing step with HARDWALL EHR 2...

Superseal 2S – New Sealing Process: A Revolution In Anodizing

Some discoveries create the history of a science:30 years after the big invention of the “cold seal”, no other considerable research/improvement has changed the way of sealing ; now, after many years of R&D in the direction of a big step ahead in the sealing process Italtecno has developed a new know-how for a sealing process with very high performance against corrosion and also against alkali while all conventional seals fail the alkali tests.
Furthermore, resistance to alkali at a certain degree is also good for profiles and sheets for architectural application due to the frequent problem of contact with concrete during building construction and contact with alkaline cleaners during cleaning of buildings.
For “conventional” corrosion in acid it is possible to make a comparison with conventional technologies by means of all laboratory tests, accelerated tests and “field” tests. Results are exceptional, much better than any conventional seal.
As regards the performance of the sealed anodic coating against alkali, it is possible, for example, to test the new seal with automotive test (Volkswagen TL 212 and others).
The new sealing will also be one of the highlights of the “Anodizing session” at the 8th Aluminium Two Thousand Congress in Milan, May 14-18th 2013, Hotel Melia and it will also be described in details during the special “Anodizing Workshop” parallel to the Congress organized by Interall and AAC (Anodizing American Council).
