    Example

    [0119] A sprayable adhesive composition having the formulation presented in Table 1 below was prepared. Unless otherwise provided in this Example, all weight percentages are based on the total weight of the sprayable adhesive composition.

    TABLE-US-00001 TABLE 1 Formulation Component Weight Percentage (%) Polymers 15% Tackifiers 30% Antioxidants <1% Solvents 30% Propellants 25% Total 100%

    [0120] The polymers, tackifiers, antioxidants, and solvent were mixed. The sprayable adhesive composition, before the propellants were added, had a viscosity of 5000 cP when measured at 25 C. using a Brookfield viscometer with a spindle #3 and a viscometer speed of 10 RPM. The various components were mixed with the propellants and a spray device was filled with the resulting sprayable adhesive composition. The sprayable adhesive composition was applied to a TPO membrane in a 2 by 6 strip and to a plywood substrate in a 2 by 6 strip. The solvent was allowed to flash off, and the TPO membrane was adhered to the plywood substrate.
