Abstract: An adhesive composition for use on a fleece-backed roofing substrate includes two components that are mixed prior to application on the fleece backed roofing substrate. The first component includes renewable polyol, catalyst, fumed silica, and surfactant. The renewable polyols are selected from any non-petroleum based polyol that is derived from a renewable source. The second component includes isocyanates, including renewable and non-renewable isocyanates.

Abstract: Sealant assemblies and methods are provided for sealing an interface between a surface and a projection extending from the surface. The sealant assembly includes a flexible member circumscribing an area to form a sealant pocket and a filling sealant at least partially filling the sealant pocket. The filling sealant and the flexible member comprise substantially the same material.

Abstract: The invention is a silt screen fence assembly which combines the use of a polymeric silt screen fabric with or without a plastic reinforcement member and a thermoplastic support stake with a hot melt adhesive to attach the silt screen fabric with or without the reinforcement member to the support stake to provide an extremely durable and tenacious bond of the screen fabric to the support stake so as to overcome the inherent problems with prior art silt screen fences wherein the mechanical bond is initially significantly weakened due to penetrating, cutting, punching, or thinning out the silt screen or reinforcement material upon assembly.
