  • Patent number: 7442726
    Abstract: A sprayable granite-like coating composition useful for forming simulated stone surfaces, such as polished granite, such surfaces having high-impact strength, superior hardness and an aesthetically pleasing look. The coating composition comprises gel resin matrix based on unsaturated crosslinkable polyester or acrylic resins, a curing accelerator composition and granules comprising thermoset resins or mixtures of thermoplastic and thermoset resins. The gel coat resins and the granules are visually differentiable, substantially immiscible and substantially equal in density. The composition, is characterized by forming coatings of uniform thickness and quick curing that even at low thickness provides a uniform granite appearance.

  • Patent number: 5688602
    Abstract: The subject invention provides a method for producing a laminated article and the laminated article resulting from such method which comprises contacting a rigid substrate with a plastic material in a liquid or semi-liquid state, said plastic material being held in place by a gasket or spacer and in contact with a flexible film and maintaining contact between the substrate and plastic material under conditions so that the plastic material hardens and adheres to the substrate to form the article. The invention also concerns a plastic edge piece which may be cast and attached to the exposed edges of the laminated article and which has the same appearance as the plastic laminate.

  • Patent number: 5504126
    Abstract: The subject invention provides an improved simulated mineral article which comprises a discrete suspended plastic material and a continuous thermoplastic matrix. The plastic material and the thermoplastic matrix are visually distinguishable and each contains a coupling agent. The subject invention also provides a method of preparing a simulated mineral article which entails preparing a liquid thermoplastic to serve as a matrix and then suspending a plastic material therein. The plastic material is composed of a thermoset plastic made from resin which comprises an acid component having thermoplastic characteristics. The invention also concerns a method of coating a thermoplastic article with a thermoset surface coat which has increased binding affinity toward the article.

  • Patent number: 5476895
    Abstract: A sprayable coating composition is useful for forming a simulated granite surface having high-impact strength, superior hardness and an aesthetically-pleasing look. The coating composition has a gel coat and granules which include thermoplastic and thermoset plastic components. The gel coat and granules are visually differentiatable, substantially immiscible and substantiatly isopycnic in density. The composition, when combined with a hardener, may be sprayed into a mold and backed with fiberglass, plastic or other suitable resin to form a panel or similar structure, or may be directly applied to surfaces to provide a simulated-granite appearance.

  • Patent number: 5465544
    Abstract: A decorative facing can be placed on a block so as to render an ordinary block decorative. This provides the advantage of reducing transportation costs, since locally produced construction blocks can be used in place of the glazed blocks produced at a relatively limited number of facilities. The facing in addition to being decorative enhances the water impermeability of the block and facilitates clean-up.

  • Patent number: 5304592
    Abstract: Granite-like plastics useful in all forms of molding and thermoforming are disclosed. The granite-like plastics include a multiplicity of particulates formed of a thermoplastic and thermoset plastic combination which are suspended within a clear or translucent matrix of the same thermoplastic material as the particulates. The particulates are maintained in suspension due to their isopynic density with the matrix. Of particular importance are granite-like acrylics that can be used in place of standard acrylics.
