Moisture cure asphaltic material and methods of use

摘要

An adhesive composition has an asphaltic base. A plasticizer, solvent, resin, calcium carbonate, fumed silica, talc an adhesion promoter, a moisture scavenger and a catalyst are included in the adhesive. The resin may be a silylated prepolymer, two part urethane, one part urethane prepolymer, or two part epoxy. Optionally a micronized polyamide wax is added to the composition. Further optionally, an asphalt hardener and/or a silica flour may be included in the mix.
