  • Spatter coat urethane roofing adhesives and their application
    Publication number: 20080006363
    Abstract: Roofing insulation and roofing elastomeric membranes are secured with a moisture-curable urethane roofing adhesive composition by spatter applying the roofing adhesive composition at an application rate of between about 10 and about 18 grams per square foot. Spatter application of the adhesive diminishes show-through (aesthetics) of the cured adhesive, while providing superior performance.

  • Composite roof structures prepared using one-part moisture curing polyurethane foaming adhesive compositions containing a reversibly blocked catalyst
    Patent number: 6305143
    Abstract: The present invention relates to composite roof structures and their preparation. The composite roof structure is prepared by applying a one-part, moisture curable, foaming, polyurethane adhesive composition to the roof deck, placing the roofing material in contact with the adhesive composition, and allowing the adhesive mixture to foam, fill, and cure. If multiple layer of the roofing material are used to form the composite roof structure, then the above procedure may be used to adhere each of the roofing material layers.
