Abstract: An asphalt-based sheet roofing material includes capsules on its upper surface. When struck, as by hailstones, the capsules break to release a film forming fluid that spreads over the surface to heal the damage created by the hailstones.

Abstract: Solar-reflective roofing granules having improved solar heat-resistance are formed by coating colored mineral particles with a coating composition including titanium dioxide nanoparticles.

Abstract: An exterior surface covering has a colored outer layer that transmits infrared radiation and an inner layer with a thermochromic pigment that absorbs heat at low temperature and reflects at high temperatures. The outer layer conceals the color change of the thermochromic pigment.

Abstract: Solar-reflective roofing granules having deep-tone colors are formed by coating base mineral particles with a coating composition including an infrared-reflective pigment. Color is provided by colored infrared pigment, light-interference platelet pigment, or a metal oxide.

Abstract: A multilayer construct includes a fluoropolymer first layer; a UV resistant fluoropolymer adhesive layer, and a third layer, wherein the fluoropolymer adhesive layer is between the first and third layers. The adhesive layer can optionally include an ultraviolet radiation absorber.

Abstract: Algae-resistant roofing shingles are prepared with granules are formed by coating mineral particles with a clay-silicate binder including a metal oxide algaecide and small organic particles. When the particles are heated to cure the binder, the organic particles pyrolyse to form pores in the coating. Release of the algaecide is controlled by the structure of the granules.

Abstract: A process for forming algae-resistant roofing shingles comprises producing algae-resistant granules, and adhering the granules to a shingle stock material. The algae-resistant roofing granules are produced by a process that includes coating mineral particles with a clay-silicate binder including a metal oxide algaecide and small organic particles. The particles are heated to cure the binder, and the organic particles pyrolyse to form pores in the coating. The release of the algaecide is controlled by the structure of the granules.

Abstract: A multilayer film includes a functional portion including one or more layers, an adhesive layer overlying a major surface of the functional portion, and a fluoropolymer layer overlying a major surface of the adhesive layer opposite the functional portion. The fluoropolymer layer includes a fluoropolymer. The adhesive layer includes an adhesive and an ultraviolet radiation absorber.

Abstract: Algae-resistant roofing granules are formed by extruding a mixture of mineral particles and a binder to form porous granule bodies, and algaecide is distributed in the pores. Release of the algaecide is controlled by the structure of the granules.

Abstract: One method for controlling edge thickness includes applying a coating to a moving substrate, thereby forming a film having a cross direction and a machine direction and one or more edges. The method also includes modifying a thickness of a first portion of the coating along one of the edges of the film, thereby forming a film having a substantially predetermined profile in the cross direction. A method of making a polymeric sheet includes applying a polymer to a moving substrate, thereby forming a sheet having a cross direction and a machine direction. This method further includes removing a first portion of the polymer from a first edge of the sheet, thereby the sheet having a substantially predetermined profile in the cross direction.

Abstract: Solar reflective roofing granules include a binder and inert mineral particles, with solar reflective particles dispersed in the binder. An agglomeration process preferentially disposes the solar reflective particles at a desired depth within or beneath the surface of the granules.
