Abstract

Polymer-based detachable coatings are used to protect industrial products and military equipment from surface damage and contamination during manufacturing and transportation. To expand their application to various industrial fields, it is essential to simultaneously implement diverse characteristics, such as low glass transition temperature, high detachability and uniformity, and high flame retardancy. In this study, we prepared Mg(OH)₂/silica composite aerogel, which was used to prepare a detachable poly(vinyl butyral) coating solution to improve the flame retardancy and reduce the glass transition temperature of the coating. Furthermore, we investigated the effect of the addition of a surfactant for achieving a detachable coating with good uniformity and flame retardancy. The coating prepared using the Mg(OH)₂/silica composite aerogel and nonionic surfactant exhibited a surface area of 496 m²/g. In addition, the coating maintained its flexibility even at sub-zero temperature (−7 °C) and exhibited significantly improved flame retardancy as it withstood fire for more than 15 s before igniting compared to the original coating.
