Abstract
Steel-based pedestrian structures are continuously exposed to wear and moisture, which can reduce surface safety and increase the risk of slip-related accidents. Under such conditions, anti-slip coatings capable of providing both strong substrate adhesion and long-term surface functionality are required.
In this study, a functional coating system for steel structures was developed using a UV-curing process. Alumina particles were incorporated into an acrylate-based resin system to control surface characteristics and impart anti-slip performance. To improve interfacial bonding with steel substrates, the coating formulation was optimized and the effects of silane coupling agents were investigated. Furthermore, a dual-layer coating structure was introduced to separate adhesion and surface functions, enabling independent optimization of each layer. As a result, the developed coating system exhibited enhanced adhesion to steel substrates while maintaining stable anti-slip performance. These findings demonstrate the potential of the proposed coating system for improving the safety of steel structures and for application in various industrial environments.
