Abstract
An elastomeric urethane composition that is the reaction product of an isocyanate and resin comprising polyetherol in the presence of a catalyst. The catalyst includes a metal selected from the group of titanium, zirconium, and hafnium. The elastomeric urethane is used in a method of making an article, which comprises reacting the isocyanate with the resin in the presence of the catalyst to form the elastomeric urethane, applying the elastomeric urethane to a mold cavity, and allowing it to cure to form a first layer. The method also includes applying a different urethane composition to the mold to form a second layer. The method further includes curing the article in the mold and de-molding the article.
