Abstract: A structural adhesive for masonry of a polyurethane adhesive base with dispersed thermal stabilizer particulate additive of a mean particle size sufficient for providing, after application and curing, cured structural adhesive thermal stability in favorable accordance to a predefined threshold. The polyurethane base provides at least 85 weight percent of the structural adhesive at a viscosity sufficient for room temperature bead application of the structural adhesive.

Abstract: An artificial turf structure comprises a top layer comprising at least two pieces of artificial turf material, the pieces positioned contiguous to each other to form a seam between the pieces; a substrate underlying the top layer; and a high solids single component moisture cure polyurethane adhesive applied between the top layer and the substrate, wherein the adhesive comprises either: A. a reaction product of isocyanates, polyols, catalyst and defoamers having a viscosity of the said reaction product in the range of 2,000 to 30,000 cps, and having water-(moisture) reactive free-isocyanate content of 5.2 to 9.2% by weight based on 100% by weight of said reaction product, or B. a reaction product of isocyanates, polyols, catalyst, defoamers and thixotropic agents having a viscosity of the said thixotropic reaction product in the range of 30,000 to 900,000 cps and having water-(moisture) reactive free-isocyanate content of 3.8 to 7.8% by weight based on 100% by weight of said reaction product.
