Soda-lime glasses exposed to humid and hot atmospheric conditions during storage or transportation corrode easily. Corroded glass loses its optical and mechanical properties. Protective systems have been developed to prevent glass against corrosion. In this study, three different types of commercial liquid corrosion inhibition systems; organic acid (OAS), polymeric (PS), and polymeric organic acid (POAS) solutions, were utilized to protect manufactured soda-lime flat glasses against atmospheric corrosion and their performances were evaluated. The chemical analyses of the corrosion inhibition systems were conducted by Fourier Transform Infrared Spectroscopy (FTIR) and thermogravimetric methods. Flat glass substrates were spray-coated with anti-corrosion solutions. The OAS solution tended to agglomerate across the glass surface, whereas the PS and POAS solutions distributed uniformly. All samples were subjected to accelerated weathering tests (500 hours at 50°C and 95% humidity) and change in their surface characteristics were examined with UV-Vis spectrophotometer, hazemeter, Atomic Force Microscope (AFM), contact angle device, and methylene blue immersion test. After accelerated weathering test the optical properties of the un-protected and PS-protected glass substrates deteriorated due to corrosion and increased roughness, while the OAS- and POAS-protected substrates maintained pristine glass quality to the most. The POAS solution stands out as it spreads evenly across the glass surface and offers high protection against corrosion. ORCID NO: 0000-0002-4518-4072
