  • Patent number: 9493627
    Abstract: The present invention relates to moldable sand compositions, methods for making the moldable sand compositions, and methods for using the moldable sand compositions. In a particular embodiment, the moldable sand composition comprises between about 70% to about 95% sand, between about 5% to about 30% water, a polar polymeric resin, a crosslinking agent, and a humectant. In an exemplary embodiment, the composition contains no oils, waxes, glycols, or rubbers. The composition is capable of becoming hardened over time in order to maintain the achieved shape, and can be re-wetted and molded again after becoming hardened.

  • Publication number: 20050136277
    Abstract: The present invention provides smooth and even ultraviolet (UV) cured powder coatings for wood comprising one, two or three layers of one or more waterborne stains, or clear or tinted waterborne basecoat coatings and one or more topcoat layers of clear or tinted clear powder coatings made from one or more than one free radical UV curing resin, one or more than one photoinitiator, and one or more than one post-blend dry flow additive, such as fumed alumina. The coatings of the present invention have a natural wood appearance, are foam free and fully coat substrates at powder coating thicknesses ranging from 0.5 mil (12.7 ?m) to 2.0 mil (50.8 ?m). Accordingly, the coatings will fully and evenly coat uneven, beveled and/or routered substrate surfaces, including open grain natural wood substrates, such as oak.
