Nanovations products are made to last - how we test product performance
Nanovations is committed to supplying products and services to its customers that meet or exceed the customer's and the industry standards and requirements. For these reasons Nanovations is certified to the ISO 9001:2008 quality standard. As a pioneering company we are constantly looking to achieve operational excellence in the provision of our products and services that we offer to worldwide clients.
Please see here a example how we test and evaluate our glass coatings.
To evaluate our products, we have tested our materials not only in real world exposed outdoor situation, but also against several other products on the market.
For the glass coating examinations we use destructive methods like abrasive wet scrub testing with abrasion test devices. Such devices are standard to evaluate the durability of coatings against wear and tear. The samples are prepared on identical glass panels, with two products next to each other. A pair of brushes are swept back and forth across the treated samples. They provide precisely controlled conditions of testing ensuring repeatability and excellent compatibility of performance between products from different manufacturers.These are standard devices to determination of wet-scrub resistance according ISO 11998 for example. Because the machine and the method are universal, everyone is able to repeat these results.
The Taber Wet-scrub tester apparatus, consisting of a reciprocating scrub testing machine with a stroke length of (300 ± 10) mm and operating at approximately (37 ± 2) scrub cycles per minute. A counter for recording the number of scrub cycles shall be provided. The complete setup looks like you can see in the following video. The weight is 500 g on each brush.
Water with a cleaning fluid can be added during the abrasive cycles.
The machine runs 37 double stroke cycles / minute . A test of 80,000 cycles takes over 40 hours to complete. This does not include the time to measure the contact angles every 1000 cycles.
Nanovations coatings can handle 40,000 - 80,000 such cycles and the reduction in the contact angle is still significantly above any competitive material after the test procedure. There are many manufacturers that offer clients a 10 year warranty and they don't even last 800 of such cycles. When we test such coatings , the contact angle of such products falls very quickly , which is a indication the coating has been removed. The test results can be documented in excel sheets that look like this:
Some glass coating supplier even warn of the use of rubber squeezes for maintenance cleaning, because the coating could be damaged. In comparison , Nanovations performed a windscreen wiper cycle test by a independent accredited US laboratory with half a million wiper cycles and of course rubber windscreen wipers. You can see why products from these manufactures perform badly in a simple wet scrub test.
Please contact us if you want to know more or to find out what products we used for the comparison tests.
