Abstract: A composite structure including a polyurea show surface, or top layer, and a polyurethane backing layer is disclosed. Preferably, the show surface of the composite structure is substantially free of volatile organic compounds and is aliphatic such that it is ultraviolet light stable. Specifically, the show surface is the reaction product of an aliphatic polyisocyanate or aliphatic polyisocyanate blend, and of a resin component which is a polyamine. The resin component reacts with the aliphatic polyisocyanate to form a polyurea. The show surface has a Shore D hardness of 70.
