Abstract:
The present invention provides building materials and methods for the manufacturer which includes an extrudable thermoplastic or thermosetting substrate having a fluorocarbon-based capstock layer applied to the substrate. The fluorocarbon-based capstock layer can further include one or more top coats for providing a variegated, colored or textured pattern. The capstock layer, with or without the top coats, preferably has a thickness less than 4 mil and contains a UV-resistant PVDF resin.
