Abstract
A resin composition includes a compound having at least two reactive hydrogen atoms and a polyurethane encapsulated particle including a core particle and a polyurethane layer disposed about the core particle. The resin composition may be used in an article and in a method of making the article. The article includes the reaction product of the resin composition and an isocyanate that are reacted in the presence of the polyurethane encapsulated particle. The method of making the article includes providing the core particle in a vessel. The method also includes introducing and combining a polyol component and an isocyanate component to encapsulate the core particle. The method further includes introducing and combining the resin composition and the isocyanate, in the presence of the polyurethane encapsulated particle, to form the article.
