Abstract
A process for the manufacturing of plastisol based synthetic coverings (e.g. floor or wall coverings) having improved resistance to soiling; and the product produced from the process is presented. The synthetic covering utilizes a wear layer formed from a mixture comprising at least one silicone polymer and a cross-linking agent. Preferably, this mixture also includes a catalyst. The mixture is deposited onto a conventional support as a wear layer. The silicone polymer is then cross-linked and the wear layer undergoes pre-gelling and gelling.
