Biobased resilient floor tile

Abstract

A biobased resilient tile includes at least one base layer, at least one film layer, and a topcoat. The base layer includes a polymeric binder and a filler. The base layer has at least about 20-95% weight of the filler and at least about 5% weight of recycled material. The film layer is supported by the base layer. The film layer is a rigid film selected from the group consisting of polyethyleneterephthalate, glycolated polyethyleneterephthalate, polybutylene terephthalate, polypropylene terephthalte, or a thermoplastic ionomer resin. The film layer includes recycled material. The topcoat is provided on the film layer. The topcoat is a radiation curable biobased coating comprising a biobased component selected from the group consisting of a biobased resin, a biobased polyol acrylate, or a biobased polyol.
