Highly water-repellent surfaces, often superhydrophobic, are characterized by water contact angles exceeding 150°. These surfaces have drawn considerable attention in recent years due to their broad potential applications, including self-cleaning technologies, antifouling coatings, frost-resistant materials, and biomedical devices that require hygienic and non-wettable properties. However, their limited mechanical durability is a major obstacle to the widespread adoption of superhydrophobic surfaces. Conventional coatings, particularly those fabricated via spray deposition or surface etching, tend to degrade rapidly under mechanical stress, such as abrasion, impact, or pressure, leading to a significant loss in water-repellent performance. In this study, we introduce a novel fabrication strategy that overcomes this limitation by employing ethyl cyanoacrylate (ECA) in combination with a specially selected primer. This approach leverages a primer-induced differential curing mechanism, where the outer layer of the ECA rapidly solidifies before the inner layer, generating hierarchical micro- and nano-scale wrinkle-like structures. These structures are crucial for achieving sustained superhydrophobicity and can be further enhanced through controlled surface modifications. The resulting coatings exhibit excellent adhesion and mechanical durability, as confirmed by roller abrasion and microscratch tests. Even after repeated wear cycles, the coatings maintain water contact angles above 150°. Nanoindentation analysis reveals superior resistance to localized pressure compared to conventional films. Furthermore, the process is simple, cost-effective, and scalable, making it suitable for various substrates, including metals, polymers, and glass. This technology holds promise for industrial applications ranging from building exteriors and automotive finishes to medical devices, offering a practical path toward robust and long-lasting water-repellent surfaces.
