  • Method for producing a cast of hydrated thermo-set materials with polyurethane elastomer molds
    Publication number: 20050189677
    Abstract: The method of the present invention is directed to solving the demolding problem during the casting of hydrated thermo-set materials. The method includes the steps of pouring a fluid thermo-set material into a mold of a polyurethane elastomer containing at least about 5 percent of a hydrophobic additive based on the total weight of the elastomer, curing the thermo-set material within the mold over a period of time, and releasing the thermo-set material from the mold.
