its excellent UV protection Tuftak XL will maintain these values over an
extended period of time even when exposed to direct sunlight.
Accelerated
Xenon tests run on Tuftak XL for 5000 hours (corresponding to more than 10
years of outdoor exposure) show a very small changing of light
transmission and yellowness index, (Tuffak XL weathering characteristic
