Wettability New and Used Instia bijuga and Gmelina arborea

The dataset is regarding physical properties and wettability of new and used Instia bijuga and Gmelina arborea. It includes data on moisture content (%), density (g/cm³), and water absorption (%) for all samples. It also provides time-series data of contact angle measurements (degrees) from sessile drop tests and processed data, such as equilibrium contact angle (θe) and wettability rate constant (K values).
