The invention relates to architectural substrates coated with a polyvinylidene fluoride (PVDF) dispersion coating to produce a weatherable material. One specific use is as a PVDF coating on a frontsheet or backsheet of a photovoltaic module for capturing and using solar radiation. The polyvinylidene fluoride coating is exposed to the environment and provides chemical resistance, low water vapor transmission, electrical insulation, and UV light protection. |
