Coated materials are widely used in the process industry. For the generation of adsorption heat exchangers for heat pumps, coated systems offer compactness, robustness as well as high performance. The heat and mass transfer properties into and through functional coating layers play a prominent role in the overall performance of the whole coated systems. In this contribution, laser flash analysis and sorption measurement methods are applied to compare the heat and mass transfer properties of the common spray coating and reactive coating. The experimental results indicate that the reactive coating technique leads to layers with better heat transfer properties and in contrast to lower mass transfer.
