  • Method of inhibiting the loss of solar reflectance over time of an exterior elastomeric
    Patent number: 6815010
    Abstract: A method of inhibiting the loss of solar reflectivity over time of an exterior elastomeric coating composition comprising an organic binder and at least one inorganic additive comprises: replacing at least a part of the at least one inorganic additive with a solid, particulate, organic polymer having a Tg greater than 70° C. An improved exterior elastomeric coating composition is also disclosed.
    Type: Grant

  • Coating bituminous substrates
    Patent number: 6528581
    Abstract: The quality of a mastic coating system for bituminous substrates is improved through the use of a topcoat composition and/or tiecoat composition comprising a water-insoluble latex polymer. The latex polymer has a Tg of from −25° C. to 20° C. and is prepared from a monomer mixture comprising: (a) at least 20% by weight of at least one hydrophobic monomer selected from the group consisting of (C8 to C24) alkyl (meth)acrylates; (b) 0 or up to 45% by weight of at least one vinyl aromatic monomer; wherein the weight of (a) and (b) together constitute at least 25% by weight of said monomer mix (c) 0 or up to 75% by weight of at least one monomer selected from the group consisting (C1 to C4) alkyl (meth)acrylates; and (d) 0 or up to 5% by weight of at least one monomer selected from acrylic or methacrylic acid; wherein when (b) is not present in the monomer mix the amount of (d) is in the range from 0 or up to less than 3% by weight.
