  • Asphalt-aluminum coating composition
    Patent number: 4202701
    Abstract: This disclosure relates to a new organic base, asbestos-free, asphalt-aluminum coating composition for use on roofs and the like. By the use of a gelling agent in place of asbestos fiber, a product with superior reflectivity is obtained which contains less aluminum than typical asbestos-containing coatings. In addition, since no water is used in the formulation of the composition, the possibility of producing such undesirable by-products as hydrogen gas or aluminum hydroxide is virtually eliminated.
