Charged B decays to three charged kaons are analyzed in the framework of the QCD factorization approach. The strong final state K+K- interactions are described using kaon scalar and vector form factors. At low K+K- effective masses, these scalar non-strange and strange form factors are constrained by chiral perturbation theory and satisfy the two-body unitarity conditions. The results of the model are compared with the Belle and BaBar data. Outside of the phi(1020) resonance region, a possibility for a large CP asymmetry is identified in the S-wave dominated K+K- mass spectra.
