Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of using a moldable sand composition comprising: molding the moldable sand composition into a desired shape; exposing the moldable sand composition to air for a period of time sufficient for the moldable sand composition to become a hardened composition; adding water to the hardened composition to make a re-wetted moldable composition; and molding the re-wetted moldable composition, wherein the moldable sand composition comprises between abo…
