Abstract
The invention relates to moisture resistant, through-wall, multicomponent copper flashing material and a continuous process for its preparation. Copper sheeting substrate having special properties is laminated on at least one side with fiberglass sheeting having special properties. The fiberglass sheeting is bonded thereto by means of a thin coating of waterbased adhesive, preferably water based polyvinyl emulsion or vinyl acetate emulsion adhesives. A continuous process provides the copper sheeting from a bulk roll to be simultaneously spray coated on both sides with liquid water based adhesive, forcefully engaging and laminating each side with the fiberglass sheeting, air drying and curing the thinly coated adhesive laminated fiberglass sheeting bonded to the copper sheeting. The final multilaminated flashing material has excellent mechanical properties and chemical resistance.
