ENVIRAL® Austria

 

Since 08 September 2012 there is a long-term test run on the Danube ferry of Ottensheim in which ENVIRAL® is testing different coating systems regarding their suitability for use "under water". We have already reported several times at this point about the partial results of the test series (see, inter alia, links).

After 30,000 hours or 3 years and 155 days in permanent contact with water, the test sheet was subjected to further examination. After cleaning the heavily polluted sheet (Fig. 1-2) we could see that the state of it is still very good. The surfaces of the sheet exhibit neither bubbles nor point corrosion. Only the flow-side edge of the sheet reveals damage, however, an infiltration of the powder coating does not take place (see. Fig. 3). This result is very satisfactory for all parties.

This long-term test is continued for another 5,000 hours. We will keep you posted about the results of these tests.
