Methods of manufacturing a belt include laying up a first elastomeric layer of a belt build on a mandrel, laying up a tensile reinforcement layer on the first elastomeric layer, where the tensile reinforcement layer contains cords coated with a water based urethane compound, and laying up a second elastomeric layer on the first elastomeric layer and the tensile reinforcement layer. The belt build may be cured in a profile-forming mold, and afterward, cut to a predetermined belt width and/or length.
