Polyurethane- and polysiloxane-based coating agents are widely used in automobiles and electronic devices for sealing. To study a component which affects their surface properties, polyurethane resins (PUR) were synthesized from polyester polyol, perfluoropolyether (PFPE) diol, and toluene diisocyanate. The coating agents were subsequently prepared by adding various amounts of PE wax, carbon black, matting agents, and silicone resin. The effects of the soft and hydrophobic PFPE diol content in the coating agent on the surface properties, such as hydrophobicity, noise generation, and friction coefficient were investigated. Although the bulk content of PFPE diol in polyols is 1.7?wt% or less, hydrophobicity, workability, friction coefficient, and noise generation of the newly designed PUR coating agents were improved while their tensile strength and abrasion resistance decreased. These results indicate that the PFPE diol chains in the modified PURs are segregated at the surface layer and affected surface properties as well as bulk properties.
