Kynar 500® Bronze Weathering Series
This series demonstrates how after 17 years in South Florida, S45° exposure, Kynar 500® PVDF resin-based coatings outperform coatings made with competitive polymer technology. In a 19 year study, Kynar Aquatec® PVDF resin-based coatings are performing similar to Kynar 500® resin-based coatings.
Kynar Aquatec® Coatings vs. Acrylic on a Cementitious Substrate
Cementitious Siding (4000 hrs QUV® B)
Color matched coatings formulated with Kynar Aquatec® PVDF resin and commercial acrylic resin were weathered together for 4000 hours in a QUV® B weathering chamber. Notice the fading and chalking on the acrylic samples in the area that was exposed to the UV light. In the chart you can see that after 4000 hours of QUV® B exposure, the Kynar Aquatec® PVDF based coatings were around 3 units delta E (ΔE) whereas the commercial acrylic paints had almost reached 9 units ΔE.
Stucco Façade of a Private Residence on Sanibel Island, FL
Sanibel Island's aggressive salt air, sea spray and humidity caused the original white paint on this home to severely chalk and degrade, as well as grow mold and algae on the shaded, moisture-prone areas. The building’s stucco exterior—originally painted with a construction-grade paint—was severely faded and flat, with no sheen to it at all. A Kynar Aquatec® resin-based coating was selected for the restoration.
The Sanibel Island Residence after being coated with a Kynar Aquatec® resin-based coating. After 8 years, there are no signs of chalking or coating degradation, and no mold or algae growth on any area of the property.
Contractors sprayed on the coating and back rolled the surface. Brushes were used in the hard to reach areas. Kynar Aquatec® resin-based coatings are easily applied with brushes, rollers, or conventional spray equipment.
8 years after completion, a panel painted with the Kynar Aquatec® resin-based coating that had been stored out of the elements in the garage, was compared to the side of the home, there was no decernable difference in color.
Kynar Aquatec® Coatings vs. Acrylic on a Wooden Substrate
A Kynar Aquatec® PVDF resin-based coating and 3 commercial arcylic house paints were applied to southern yellow pine and exposed in South Florida at 90° facing north. After only 16 months of exposure the arcylic paints were showing signs of mold and mildew growth. Kynar Aquatec® resin-based coatings are inherently resistant to mold, mildew, and fungal growth.
Kynar Aquatec® Coatings vs. Polyolefin Molded Shutters
This deep green injection molded polyolefin shutter was cut in half vertically. The right half of the shutter was painted with a color-matched Kynar Aquatec® resin-based coating. The shutter was then placed on exposure in Southern Florida, facing south at 45°. After 10 years of exposure the original uncoated polyolefin substrate has faded substantially compared to the Kynar Aquatec® coated half.
Kynar Aquatec® Coatings vs Acrylic in Cool White Roofing Applications
In 2006, after carefully considering various high-performance and sustainable product options, the MGM Grand Hotel management team decided to use an ultra-durable, bright-white topcoat formulated with Kynar Aquatec® PVDF fluoropolymer resin for the new cool roof of the hotel’s main building.
Upon inspection of the cool white roof on MGM Grand’s main building in May 2016, ten years later, the total solar reflectance (TSR) measurements remained high, at 82 percent, compared to an original TSR value of 90 percent.
While measuring the TSR of the Kynar Aquatec® resin-based coating, several elastomeric acrylic repair patches on the roof were noticed. In contrast, the dark appearance of newer elastomeric acrylic patches are a good demonstration of the color retention and dirt pickup resistance of the Kynar Aquatec® resin-based coating.
