Abstract

A polydiorganosiloxane is useful in a composition and a method for preparing a wood plastic composite article. The wood plastic composite article is useful as a building material. The polydiorganosiloxane may be added to the composition in liquid form or may form part of a solid carrier component used to make the wood plastic composite article.
