Abstract
A suitable one-component polyurethane resin matrix for the sealant was developed by screening different chain extenders and soft segment types. This polyurethane was then compounded with nano-calcium carbonate filler and dibutyl phthalate to form the final one-component polyurethane sealant. The resulting PUA sealant was systematically evaluated through measurements of its mechanical properties, adhesion performance, curing time, and thermal behavior, providing a comprehensive assessment of its overall performance.Keywords
