OxSiSeal is very resistant to high temperature and thermal shock. This is demonstrated here with a butane flame applied directly to the surface of an aluminum sheet. The temperature rises first to a point where the metal glows red and then to a point where the aluminum melts. At this stage the molten aluminum flows away from OxSiCoat leaving a transparent window (with some remaining aluminum debris) through which the red handle of a tool can be seen.
The film clips above and below demonstrate resistance to the highly alkaline solutions of one molar sodium hydroxide at 75 degrees Celcius. The above film shows a high quality hard anodize coating about 50 microns thick being dissolved by the solution in about 30 seconds. The still to the right shows the exposed aluminum on the lower half after the test. The film below shows the thin OxSiCoat being exposed for 30 minutes to the same solution. The still photo to the right is the sample after exposure These clips demonstrate only a couple of OxSiCoat’s remarkable properties.
