  • Publication number: 20040048025
    Abstract: A composite tile is fabricated to resemble stamped concrete or interlocked brick arrangements. The composite tile may be produced in various shapes, sizes, surface designs and colours and can be applied to outdoor surfaces, for example, asphalt, concrete, or wood surfaces such as driveways, sidewalks, porches, balconies and decks. In one embodiment, a composite tile is provided that comprises a durable, polymer containing mineral layer; an adhesive backing; and a removable protective layer covering the adhesive backing. One method for making the composite tile comprises applying an adhesive backing to a durable, polymer containing mineral layer.

  • Patent number: 6565935
    Abstract: A structure comprising a filled thermosetting polymer composition. The filled thermosetting polymer composition has a mineral filler content of at least 92% by weight and not more than 8% by weight of thermosetting polymer and a co-efficient of thermal expansion that is less than 15×10−6 in/in/° C. The filler is a mineral particulate filler with generally rounded edges and the thermosetting polymer composition has a density that is at least 95% of the theoretical density for the filler and polymer. Embodiments of the composition per se may be used to form a structure for resisting acid solutions.

  • Patent number: 5041242
    Abstract: A composition for forming electrically-conductive coatings, consisting essentially of a water-urethane resin, a plurality of carbon pigments including carbon black and natural graphite, each carbon pigment having a different preselected average particle size, and sufficient water to permit dispersion of the resin and carbon pigments therethrough. The ratio of resin to total carbon pigment and the ratio of each carbon pigment to total carbon pigment is selected such that a coating formed upon air drying of the composition has a resistance of less than 1 ohms per square and as low as 0.15-0.3 ohms per square.
