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.

A reinforced water-resistant board includes a cover board with a reinforced water-resistant membrane applied to a surface of the cover board. The reinforced water-resistant membrane includes a primer layer, a reinforced membrane, a traffic coat, and a sealing layer. The primer layer is applied over the surface of the cover board. The reinforced membrane includes fleece soaked in a liquid resin and is applied over the primer layer. The traffic coat is bonded to the reinforced member. The sealing layer is applied over the traffic coat.

A roofing product has a substrate having a binder layer and roofing granules on a majority of the binder layer, such that an exposed portion of the binder layer does not have the roofing granules. In addition, reflective particles may be located on the exposed portion of the binder layer. The reflective particles are smaller in size than the roofing granules, and the reflective particles have a solar reflectance of greater than 40%.

A cool roofing system includes highly reflective calcined kaolin particles having a solar reflectance of 80% to 92%. When applied to a roofing substrate, the highly reflective kaolin particles produce a roofing system having a solar reflectance greater than or equal to 70%.

Embodiments of the disclosure pertain to a method of manufacturing a composite panel that includes the steps of providing a layer of porous material, and dispersing a particulate material further comprising a binder composition mixed therein onto the layer of porous material. The method includes using a vacuum to at least substantially retain the particulate material on the layer of porous material, and conveying the retained particulate material toward an application mechanism. The method also includes using the application mechanism to associate a polymeric substrate with the particulate material, and applying a backing layer onto the polymeric substrate and the particulate material. The method further includes containing the retained particulate material, the polymeric substrate, and the backing layer together for a period of time to cure the polymeric substrate, the particulate material, and the backing layer together; and completing the composite panel by removing the layer of porous material therefrom, and cleaning off residual therefrom.

Embodiments of the disclosure pertain to a panel usable for forming a surface, the panel having an at least one finish element; a backing material; and a polyurethane material cured between the at least one finish element and the backing material. Upon curing, the polyurethane material forms a structural substrate having a first side and a second side. Upon curing, the backing material is adhesively bonded to the first side. Also upon curing, the at least one finish element is adhesively bonded to the second side.

In certain embodiments, the invention relates to an article having a liquid-impregnated surface. The surface includes a matrix of solid features (e.g., non-toxic and/or edible features) spaced sufficiently close to stably contain a liquid therebetween or therewithin, wherein the liquid is non-toxic and/or edible. The article may contain, for example, a food or other consumer product, such as ketchup, mustard, or mayonnaise.
