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.

The present invention relates to a corrosion inhibitor and a corrosion inhibiting coating provided for coating a metal, particularly but not exclusively steel. The inhibitors pigment will also protect aluminium and magnesium alloys. The corrosion inhibitor particularly protects a sacrificial coating such as zinc or zinc alloy on galvanised steel, which in turn therefore provides improved corrosion resistance to the underlying steel. The present invention comprises an organic cation in a cation exchange resin.
