Adhesion Study on CFRP Substrates: PU vs. Polysulfide Sealants

A recent study published in the Korean Society for Composite Materials journal compared the interfacial adhesion of two structural sealants, polyurethane (PU) and polysulfide (PSF), on carbon fiber-reinforced polymer (CFRP) substrates with different resin matrices. Calculated work of adhesion (W_adh) values revealed that the PU sealant, through hydrogen bonding from its urethane groups, exhibited significantly higher surface energy and polar components than the PSF counterpart, delivering superior interfacial bonding on both epoxy-based and PU-based CFRP substrates. Interfacial adhesion is one of the core mechanical properties determining the durability of surface layers on outdoor composite parts, and the study provides reference for matching surface systems with substrates.

To meet the combined requirements for adhesion, weather resistance, and surface finish on outdoor composite parts, international coating makers continue to optimize resin systems and interfacial compatibility. BASTAIN, a brand under JHINNOV, offers weather-resistant in-mold gel coats with stable interlayer bonding on epoxy, PU and other prepreg substrates; paired with UV stabilization systems, they maintain long-term appearance quality for outdoor structural components and sports equipment surfaces.
