Experimental Data and Mixture-Model Outputs for a PET/ZnO-Reinforced Epoxy Corrosion-Resistant Coating for Roofing Applications

This dataset contains the modelling files and characterisation outputs supporting the study titled “Recycling PET Waste for Corrosion-Resistant Roof Coating: A Sustainable Approach to Enhance Protective Performance.” The data were generated to enable independent verification, replication, and further analysis of the formulation, performance evaluation, and optimisation of the corrosion-resistant composite coating (CRCC).
The dataset includes the Design-Expert® mixture simplex-lattice model file with the inputs being the raw measurements from mixture-designed coating formulations composed of epoxy resin (ER), recycled polyethylene terephthalate (PET) waste powder (PW), and zinc oxide (ZnO). Experimental data comprise average corrosion rate measurements obtained from immersion testing under alkaline exposure conditions, adhesive strength values determined via pull-off adhesion testing. From the Design-Expert® mixture simplex-lattice model file, the ANOVA tables, regression coefficients, optimisation constraints, predicted versus experimental values, and residual diagnostics used to evaluate model adequacy and predictive reliability can be obtained.
Fourier Transform Infrared (FTIR-ATR) spectra used to confirm component incorporation and epoxy cure progression are provided in both raw formats.
