ABSTRACT:
An elastomeric composition includes a reaction product of an isocyanate component and a resin component comprising a polyol and a polyetheramine in the presence of a first catalyst comprising a metal and a second catalyst comprising an amine. An elastomeric system and a method of making an elastomer are provided. The method includes providing the isocyanate component and the resin component, combining the resin component and the isocyanate component in the presence of the first and second catalysts to form an elastomeric composition, applying the elastomeric composition to a mold having a mold cavity, curing the elastomeric composition to form the elastomer, and demolding the elastomer from the mold cavity. An article including a first layer formed from the elastomeric composition emits less than 100 μg/g of volatile organic compounds over 0.5 hour at 90° C.
