Abstract
The present invention provides a self-collapsing, moisture curable one component polyurethane foam (1K PU) composition from moisture curable polyurethane prepolymers and to methods of making weather resistant barriers and formed in place gaskets therefrom. The foam compositions are packed under pressure with a blowing agent. In the methods, the foams are applied to gaps in the exterior (sheathing) of a building under construction and collapse on cure to enable application an aqueous weather barrier coating thereover within an hour. The foams also cure when applied on or adjacent a structure to form a foam gasket that enables installation of additional structural elements over or adjacent the foam gasket without bowing or damage to the structure treated.
