The application of a dinuclear manganese complex (MnMeTACN) as a catalyst in the oxidative drying of alkyd coatings is described. Experimental results on the film properties (drying time and film hardness) for various solvent- and water-borne alkyd coatings demonstrate that MnMeTACN is a potential alternative for commercially-available Co- and Mn-based catalysts. MnMeTACN appears to be suitable for both water-borne and solvent-borne alkyd systems. Confocal Raman microscopy is used to study the depth profile of the drying of alkyd coatings catalysed by different catalysts, and it has been found that slow surface drying is somewhat compensated by relatively fast deep layer drying.
