Enhancing the Radiata Pine and Spotted Gum Coating Performance against Weathering using UV Absorber
Keywords:
Coating, UV absorber, Weathering, WoodAbstract
Coatings are important to reinforce the competitive position of wood. The 320 wood samples were used in the study, with two species (Radiata Pine and Spotted Gums), two weathering conditions (Natural Exposure and QUV), and two coating systems (solid colour and clear). The effects of colour changes of the wood surface after natural weathering test (1 year) were studied. The most effective protection for stabilising wood colour involved coating radiate pine with a UV absorber and coating spotted gum with an untreated UV absorber.
