- Abstract
- The European Biocidal Products Directive (BPD) challenges the (wood) coating manufacturers to produce coatings with reduced amounts of biocides or even avoid using biocides. Moreover, coatings should also comply with the European VOC Solvents Directive, forcing the industry to switch to low/non-VOC constituents. Given this legislation, an integrated view on the interaction of coating-substrate-environment is essential if the performance of future coatings should enhance or at least remain comparable adequate. Research concerning fungal deterioration of wood coatings is exactly in the scope of such an approach. In this work a modified version of the European standard blue stain test for coatings (EN152) is presented which is further complemented with testing in a controllable environment, the so-called Fungal Control Unit (FCU). This test setup combines the advantage of accelerated artificial weathering, biological deterioration and mimicry of the outdoor situation. Both additional tests give complementary information on fungal susceptibility linking them with outdoor infestation. Samples are analysed in 3D to acquire in-depth knowledge on fungal growth. In addition, 3D/4D X-ray sub-micron tomography and accompanying image processing is illustrated as a powerful non-invasive technique for coating research, visualizing at the same time coating, wood and fungus and linking their characteristics. Ultimately, combining fungal growth data with physicochemical information of the coating (film formation, UV degradation …) and wood (water absorption, nutrient content …) should lead to cyberfungal deterioration modelling in 4D supporting manufacturers in the development of the innovative ‘green’ coating.
