Abstract:
1. A method of producing a polymeric matrix adhesive, said method comprising: a) providing a silane end-capped polymeric mixture, wherein the silane end-capped polymeric mixture comprises a silane end-capped prepolymer urethane, wherein the silane end-capped prepolymer urethane is produced by combining a silane and a prepolymer urethane, wherein the prepolymer urethane has an average NCO content of between about 9 to 16; b) adding an aliphatic quencher; c) adding reinforcing extender; and d) adding a thixotropic agent; wherein the prepolymer urethane comprises a slow-cure urethane prepolymer having a functionality (Fn) between about 2.5 and 2.55 and an NCO content between about 15 to 18%, and a flexible binder urethane prepolymer having a functionality (Fn) of about 2 and an NCO content between about 7 and 10%; wherein the method produces the polymeric matrix adhesive such that the polymeric matrix adhesive is waterproof and pH-resistant.
