An branched polyether epoxy resin called FBEPO was synthesized by the ethoxylated pentaerythritol and epichlorohydrin. It can be added to the silane modified polyether sealant (SMP adhesive) as a tackifier. The effects of tackifier (FBEPO) which added to the SMP adhesive on the tack-free time, tensile strength, elongation at break, elastic recovery were studied. Research shown the effect of the bonding between SMP adhesive prepared by only adding FBEPO or aminosilane coupling agent and the precast concrete board (PC board) was general, but adding aminosilane coupling agent and FBEPO at the same time to the SMP adhesive could significantly improve the mechanical properties, elastic recovery rate and adhesion of SMP adhesive. The effect is the best when the amount of aminosilane is 0.5% (w/w) and the amount of FBEPO is 1–2% (w/w).
