摘要:
An elastomeric urethane composition includes the reaction product of a resin composition, including a polyol, and an isocyanate. The resin composition and the isocyanate are reacted, in the presence of a first and a second catalyst, to form a polyurethane elastomer. The first catalyst includes a metal selected from the group of iron, titanium, zirconium and hafnium. The second catalyst includes an amine. The elastomeric urethane composition may be used in a method of making an article. The method includes reacting the resin composition and the isocyanate to form the elastomeric urethane composition, applying the elastomeric urethane composition to a mold cavity, and allowing the elastomeric urethane composition to cure to form a first layer. The method also includes applying a urethane composition, different from the elastomeric urethane composition, to the mold to form a second layer, curing the article in the mold, and de-molding the article from the mold.
