Abstract

This study analyzes the water-retaining mechanism of surfactant-based curing agents. Curing agents on the water surface were observed with the help of a Brewster angle microscope, which is often employed for studying ultrathin films on liquid surfaces. Curing agents of various concentrations were prepared and instilled into pure water. The resulting surfactant effect on the water surface was subsequently observed. When a curing agent with concentration lower than 10% was instilled, the film spread over the water surface. However, when a curing agent with concentration higher than 17% was instilled, several lumps formed instead of a film, which primarily indicates aggregated surfactants. The film-forming process observed in this study indicates that curing agents having low concentrations can significantly suppress the rate of water evaporation.
