Extreme weatherability
Natural elements, such as sunlight, water, wind, and air, drastically break down coatings over time. The heart of the Kynar Aquatec® PVDF technology is the carbon-fluorine (C-F) bond. The C-F bond is one of the strongest bonds known and it is the basis for the extreme weatherability of Kynar Aquatec® PVDF resin-based coatings.
Kynar Aquatec® coatings provide the protection of the traditional Kynar 500® resin-based coatings, in a water-based, low VOC, field or factory-applied coating. After 10 years exposure in the hot, Florida sun, coatings based on Kynar Aquatec® PVDF resin are behaving similar in performance to the traditional Kynar 500® PVDF resin-based coatings. The graph below compares the weathering performance of Kynar Aquatec® resin-based coatings with that of Kynar 500® resin-based coatings and conventional acrylic-based coatings..
Fade is the lightening in color of a pigmented paint due to the effects of light, heat, time, temperature, and chemicals. Fade is measured in Delta E (ΔE) Hunter Units in the L,a,b color space. This measurement indicates the total difference between original color and exposed color. The larger the ΔE, the larger the color difference between the original color and the exposed color. 1 ΔE unit is the smallest difference detected by a trained eye.
