  • Patent number: 5498645
    Abstract: A modeling dough comprising a polar polymeric resin, water, a gellant, and a filler provides a dough resistant to flaking, cracking, and crumbling. In the disclosed invention, the polymeric resin is gelled, thereby providing a water-based resin system that is not sticky yet very ductile. After the dough is air-dried, the components are bound into a solid, durable product. The filler accounts for a large portion of the volume of the dough, so the overall volume is not greatly affected by water loss upon drying. The dough is water-based and easy to wash from skin, carpets, and other surfaces. Dyes and pigments can be easily incorporated into the formula. The dried product is sandable and paintable.

  • Patent number: 5171766
    Abstract: A modeling dough comprising gelled poly(vinyl alcohol), water and a filler provides a dough resistant to flaking, cracking, and crumbling. In the disclosed invention, the poly(vinyl alcohol) resin is gelled, thereby providing a water-based resin system that is not sticky yet very ductile. Prior to drying, the dough also exhibits the properties of bounceability and the ability to pick up newsprint. After the dough is air-dried, the poly(vinyl alcohol) resin serves to bind the components into a solid, durable product. The filler accounts for a large portion of the volume of the dough, so the overall volume is not greatly affected by water loss upon drying. The dough is water-based and easy to wash from skin, carpets, and other surfaces. Dyes and pigments can be easily incorporated into the formula. The dried product is sandable, carveable and paintable.
