Titel
A comparative weathering study on pine species in Germany and New Zealand
Abstract
The weathering of typical usued coatings on pine sapwood in Germany and New Zealand has been evaluated in a comparative weathering trial. The New Zealand site had a climatic index 50 % more challanging. Significant differences in performance relating to coating, species, site and exposure are represented. The coating and site had most significant effects, while species had least. A solvent borne stain and a hybrid paint qualified for stable end-use situations in both countries. An acrylic paint performed better in Germany while an alkyd gave the poorest performance of the four coatings tested. More effective fungicidal coating properties are required in New Zealand to suppress mould growth. Areas of deficiency for internationalising the European weathering standard EN 927 are discussed.
