Wood-plastic composites (WPCs) have several exterior applications where they are easily exposed to ultraviolet (UV) radiation. The paper presents the current situation in a field of UV protection of WPCs, including the most commonly used protective agents and methods, such as UV absorbers and hindered amine light stabilizers (HALS). Surface dressing methods, such as painting, coating and film coating are not included. The focus of the paper is on the ways of how to integrate UV protection comprehensively over the material. The work is a literature review and practical experiments are not included.
