This data package is part of the parent data package “Datasets for “Penetration Coefficients of Commercial Nanolimes and a Liquid Mineral Precursor into Pore-Imitating Test Systems”” (DOI 10.48606/49) belonging to the open access journal publication “Penetration Coefficients of Commercial Nanolimes and a Liquid Mineral Precursor into Pore-Imitating Test Systems - Predictability of Infiltration Behavior", which was published in MDPI Materials in 2023 (DOI 10.3390/ma16062506). It contains data from physicochemical characterization measurements for water, ethanol, iso-propanol, four different commercial nanolime formulations, and a liquid mineral precursor based on complex coacervation; as well as polymethylmethacrylate (PMMA) and polydimethylsiloxane (PDMS). For more detailed information, please see the overview README file for the experimental data.
