Patent number: 6607818Abstract: A visually decorative material having bulk decorative effects which may be used as a surface covering or for creating decorative objects, and the method of manufacturing same. The material is formed of a pigmented castable liquid vehicle such as a resinous polymer or glass having dispersed therein a quantity of discrete particles which have a higher specific gravity than the liquid vehicle. The material is formed by pouring the vehicle-particle composite onto a suitable backing. As the liquid flows onto the backing, the particles sink and disturb the uniformity of the pigment distribution. This causes the desired bulk decorative effects in the form of “comet-tails” and other dimensionally extended streaks and curves. The backing may be removed after the castable liquid solidifies or may be left in place to create a laminate. As a floor-covering, the material may be poured in place onto a suitable sub-flooring.

Patent number: 6592977Abstract: The invention provides for a substrate coated with a non-stick coating which resists abrasion force, the coating comprising a fluoropolymer resin containing ceramic particles to deflect the abrasion force away from the coating wherein the ratio of the thickness of the coating to the longest diameter of said ceramic particles is in the range of 0.8-2.0. Further, the invention provides for a substrate coated with a non-stick coating which resists abrasion force, the coating comprising an undercoat and an overcoat, each containing fluoropolymer resin, the undercoat also containing ceramic particles extending from the undercoat, the overcoat telegraphing the particles extending from the undercoat through the thickness of the overcoat to deflect the abrasion force away from the coating. Preferably, the ratio of the combined thickness of the undercoat and the overcoat to the longest diameter of the ceramic particles is in the range of 0.8-2.0.Type: GrantFiled: June 26, 2001Date of Patent: July 15, 2003Assignee: E.
