    The science behind the 3M copper granule

    “The Science behind 3M copper-containing granules is based on principles of copper ion leach rates. While the teams experimented with a variety of solutions decades ago using other metals and materials, we discovered copper-containing granules to be a highly effective method to help prevent the black streaks caused by algae and we continue that science today with active research programs on shingle test decks and roofs in a variety of locations”
