A liquid epoxy resin composition is provided. In preferred embodiments, the liquid epoxy resin composition is free of bisphenol A, bisphenol F, and bisphenol S, including epoxides thereof, and is useful in preparing a polyether polymer having utility in coating compositions, including, e.g., coating compositions for use on food or beverage containers.

A process for producing a viscous epoxy syrup from at least one liquid multifunctional epoxy, comprising the steps of: adding an initiator selected from the group consisting of electron-poor monoisocyanate, photoinitiator and thermal initiator to at least one liquid multifunctional epoxy; mixing the components; polymerizing the multifunctional epoxy such that the viscosity of the resulting epoxy syrup is at least twice as high, preferably at least four times as high and in particular at least ten times as high as the viscosity of the employed epoxy in the unreacted state
makes it possible to produce epoxy adhesives having pressure-sensitive properties.

A low-modulus high-adhesion silane-modified polyether sealant for prefabricated buildings is provided by including a composition A and a composition B, wherein the composition A includes silane-modified polyether, plasticizer, hydroxy-terminated branched polyether, branched polyether epoxy resin, coupling agent, thixotropic agent, silica, reinforcing filler A, hollow glass microspheres and toner, and the composition B includes plasticizer, hydroxy-terminated branched polyether, light stabilizer, reinforcing filler B, organotin catalyst and amine curing agent. The present disclosure also optimized the various ingredients in the silane-modified polyether sealant, and a formulation of sealant having the best bonding effect was obtained. The two-composition polyether sealant system has good compatibility, greatly improves the adhesive properties thereof, achieves a good adhesion and waterproofing effect without needing to be used with a priming coating, and also avoids the risk of water leakage caused by misoperation in the applying of the priming coating existing in the prior art.
