SINGLE COMPONENT MOISTURE-CURE POLYURETHANE ADHESIVE FOR SYNTHETIC TURF INSTALLATIONS

摘要

An artificial turf structure comprises a top layer comprising artificial turf, a substrate underlying the artificial turf, and a high solids single component moisture cure polyurethane adhesive applied between the artificial turf and the substrate, wherein the adhesive comprises either A a reaction product of isocyanates, polyols, catalyst and defoamers having a viscosity ofthe said reaction product in the range ol 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 reactive free-isocyanate content of 3 8 to 7 8 % by weight based on 100% by weight of said reaction product.
