Charged B decays to three charged kaons are analysed in the framework of QCD factorization approach. The strong final state K+K-interactions described using kaon scalar and vector form factors. non-strange strange factors at low K+K- effective masses constrained by chiral perturbation theory satisfy two-body unitarity conditions. latter stem from properties meson-meson amplitudes which describe all possible S-wave transitions between coupled channels consisting two kaons, pions four pions. fitted data on electromagnetic interactions. model results compared with Belle BaBar data. Away phi(1020) resonance, dominated mass spectra, a possibility for large CP asymmetry is identified.
