    Abstract: Seal a fenestration opening that contains a gap having a width of greater than 1.6 millimeters by providing a dispersion having the following components dispersed in an aqueous phase: (i) a film-forming polymer binder having a glass transition temperature in a range of −100 degrees Celsius to −20 degrees Celsius; (ii) a shear thinning rheology modifier at a concentration sufficient to cause the dispersion to have a Brookfield viscosity greater than 300,000 centiPoise as measured using spindle #3 at 0.3 revolutions per minute; and (iii) optionally, a filler; and then spraying the dispersion directly onto the building elements within the fenestration opening so as to form a continuous coating over the building elements and gap within the fenestration opening; wherein there is an absence of reinforcement or sealing material filling or spanning the gap prior to spraying the dispersion over the gap.

    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.

    Abstract translation: 本发明提供了一种防湿可固化聚氨酯预聚物的自塌陷性，可湿固化的单组分聚氨酯泡沫（1K PU）组合物，以及制备耐候性屏障并形成垫圈的方法。 泡沫组合物用发泡剂在压力下包装。 在这些方法中，泡沫被施加到正在建造的建筑物的外部（护套）中的间隙，并且在固化时崩溃，以使其在一小时内能够施加水性天气屏障涂层。 当应用在结构上或邻近结构时，泡沫也固化以形成泡沫垫片，其可以在泡沫垫片上或附近安装附加的结构元件，而不会对被处理的结构产生弯曲或损坏。

    Abstract: Seal a fenestration opening that contains a gap having a width of greater than 1.6 millimeters by providing a dispersion having the following components dispersed in an aqueous phase: (i) a film-forming polymer binder having a glass transition temperature in a range of −100 degrees Celsius to −20 degrees Celsius; (ii) a shear thinning rheology modifier at a concentration sufficient to cause the dispersion to have a Brookfield viscosity greater than 300,000 centiPoise as measured using spindle #3 at 0.3 revolutions per minute; and (iii) optionally, a filler; and then spraying the dispersion directly onto the building elements within the fenestration opening so as to form a continuous coating over the building elements and gap within the fenestration opening; wherein there is an absence of reinforcement or sealing material filling or spanning the gap prior to spraying the dispersion over the gap.

    Abstract: The present invention provides methods of making block resistant coated substrates, such as boards, sheets, panels, tiles, assemblies or membranes for use in building and construction, such as for exterior use, the methods comprising coating a substrate with a coating composition of one or more aqueous emulsion polymers and one or more photoinitiators, such as a hydrogen abstraction initiator, onto the substrate to form a coated substrate, at least partially curing or drying the coating, and exposing the at least partially cured coating on the coated substrate to UV light to cause the photoinitiator to react with itself or with the coating composition. In the methods, the wavelength of the UV light used preferably matches or at least overlaps the spectral activation or excitation window of the one or more photoinitiators.
