Abstract
This invention relates to a process for forming a PVC article having a weatherable coating by the in-line spray, roll-coat, brush-coat, gravure print, flexographic print, thermal transfer coat or inkjet application of a polymeric solution onto extruded PVC as it is being extruded. The invention also relates to rigid PVC articles coated by the process. A polyvinylidene fluoride coating can be applied to PVC to form an article having improved gloss, good weatherability, good color retention and stain resistance.
