| Abstract: | In this paper,elastic one-component polyurethane sealant was studied The sealant contained a preporymer which was prepared by reacting of the polyether with two or three.functionalities with TDI.some,of fillers were added to the prepolymer to make the sealant The effects of TDI,reaction temperature,composition of polyether and fillers on the performance of the sealant, were also discussed. |
