A silane is added to a prepolymer urethane to react with the urethane and at least partially end-cap the urethane. A reinforcing extender and a thixotropic agent are added to the composition. Methylethylketoximino (MEKO) silane is further added to the composition. When applied to a substrate, the adhesive composition has a tack-free time of at least about 90-120 minutes. The adhesive is cured to a final product that is waterproof, hydrolytically stable, and pH resistant. ## Claims ### Claim 1 A curable pressure sensitive, waterproof adhesive mixture comprising: a) a urethane component at a range of about 30-50 wt % of the mixture, wherein the urethane component has an average NCO content of about 7% to 23%, wherein the urethane component comprises at least one urethane selected from a group consisting of a slow-cure urethane having a functionality (Fn) of about 2.5 to 2.55 and an NCO content of about 15 to 23%, and a flexible binder urethane having a functionality (Fn) of about 2 and an NCO content of about 2 to 10%; b) a first silane component at a range of about 2-10 wt % of the mixture, wherein the first silane component comprises an amino-functional alkoxysilane polymer having terminal silanol groups; c) a second silane component at a range of about 2-10 wt % of the mixture, wherein the second silane component is a vinyltris(methylethyl-ketoximino)silane; d) a reinforcing extender at a range of about 2-10 wt % of the mixture; and e) a thixotropic agent at a range of about 2-10 wt % of the mixture; wherein when the adhesive mixture is applied to a substrate, the second silane component suppresses the cure rate of the mixture, and thus the adhesive mixture has a tack-free time of at least about 90 minutes, wherein the adhesive mixture is waterproof, hydrolytically stable, and pH-resistant. ### Claim 2 (depends on 1) The mixture of claim 1 further comprising about 15-40 wt % of a polyol component having an average molecular weight of at least about 4,000 g/mol. ### Claim 3 (depends on 1) The mixture of claim 1, further comprising about 5-15 wt % of an aliphatic quencher. ### Claim 4 (depends on 1) The mixture of claim 1, further comprising about 2-10 wt % of a tackifier. ### Claim 5 (depends on 1) The mixture of claim 1 further comprising carbon nanofibers, wherein the nanofibers increase electrical conductivity of the adhesive mixture, and wherein each carbon nanofiber has a fiber diameter of about 120 to 160 nm. ### Claim 6 (depends on 1) The mixture of claim 1, further comprising an inherently static dissipative (IDP) component, wherein the IDP component decreases surface resistance of the adhesive mixture. ### Claim 7 (depends on 6) The mixture of claim 6, wherein the IDP component is selected from a group consisting of polypropylene, polystyrene, polyethylene, and acrylic polymers. ### Claim 8 (depends on 1) A method of adhering a first substrate to a second substrate, the method comprises providing the adhesive mixture of claim 1; applying the adhesive mixture to a surface of the second substrate to form an adhesive film on the surface; applying the first substrate to the adhesive film within about 120 minutes after forming the adhesive film; applying pressure to an external surface of the first substrate, the second substrate, or both, thereby bonding the first substrate and the second substrate together; and curing the adhesive film for at least 60 minutes after bonding. ### Claim 9 (depends on 1) A method of installing a flooring material to a floor substrate, the method comprises providing the adhesive mixture of claim 1; applying the adhesive mixture to a surface of the floor substrate to form an adhesive film on the surface; applying the flooring material to the adhesive film within about 120 minutes after forming the adhesive film; applying pressure to an external surface of the flooring material, thereby bonding the flooring material to the floor substrate; and curing the adhesive film for at least 60 minutes after bonding.
