ABSTRACT:
This invention relates to a process for coating a substratum sheet material, such as woven fabrics, by first removing from the substratum material any moisture that does normally exist therein, and then coating the substratum material with a coating composition with no moisture, air or other impurities being trapped between the substratum and the coating. Novel products produced by this process comprise new compositions of sheet materials having improved weathering characteristics including stability against ultraviolet degradation for improved service in highly transparent or translucent coverings for roofs and solar devices.
