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 20 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.
Kynar Aquatec® Coatings vs. Acrylic on a Wooden Substrate
A Kynar Aquatec® PVDF resin-based coating and 3 commercial acrylic house paints were applied to southern yellow pine and exposed in South Florida at 90° facing north. After only 16 months of exposure the acrylic 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.
