NASA did an experiment whose results shocked the coating industry. The study was conducted in 2013 – 2014 to find a coating that had excellent corrosion protection properties, the lowest impact on the environment, and no zinc, heavy metal, or isocyanate. The results showed the newest competitor on the block to be the clear winner. In 60 years of testing at the Cape the highest score ever on a scale of 1-10 had been a 9.2. In this test EonCoat received the first ever 10. For the Full Report click here.

The experiment takes 18 months of beachside exposure. The National Aeronautics and Space Administration or NASA took some of the coating industry’s best corrosion protection coatings and compared them side by side. The coatings, applied by NASA, were subjected to the vaunted NASA Beachside test, generally agreed to be the toughest real-world test to introduce corrosion. Some of the brands, were EonCoat, PPG, Sherwin Williams & Carboline, to just name a few.

HOW THE EXPERIMENT WORKED?

Some of the test panels had a steel cup welded onto the test panel. This measures how the coatings protect both welds and areas where saltwater pools. NASA then coated all the test panels with coatings from various manufacturers. NASA tested panels with the primer only and then tested separate panels with a full 3 coat system recommended by the manufacturer. In the case of EonCoat, the testing was just the single coat in both comparisons. In a separate test, the coated panels were given an X scribe to measure scribe creep.

The panels were set on a stand 100 feet from the high tide mark, sitting at a 45-degree angle facing the Atlantic Ocean. Every 4 hours a sprinkler system sprayed seawater directly on the panels. This continued for 18 months.

At six-month intervals, the panels were photographed and evaluated for finish, corrosion & overall performance. NASA’s report shows photos at

4.   18 months

It is worth noting that EonCoat was the only coating system without VOCs, HAPs, or Toxins. We were also 100% free of zinc, heavy metals, & isocyanates. No other coating met all those standards in these tests. EonCoat was also one of the two single-coat systems. Sherwin Williams, Carboline, & PPG all had multiple coat systems.

Results

Let’s first look at the “X” Scribed panels. The pictures tell the story. The image below shows the results after 18 months of the toughest real-world conditions.

Below are the results for the welded panels. NASA uses this test because welds are known to be the weak link of any structure when it comes to corrosion. The results prove this. See that only EonCoat survived this toughest of all tests.

The results speak for themselves. It is worth noting that 2 other coatings performed reasonably well. Both contain zinc, heavy metals, or isocyanates. Only EonCoat was inorganic, VOC-free, and a single coat.

EonCoat is the solution to corrosion in today’s world. If you’re interested in EonCoat please contact us. If you want to read the full NASA report please click here.
