Abstract: Surface coverings and surface covering components and methods for forming them using slot die coating are disclosed. The methods involve applying a plurality of wet layers to a substrate simultaneously or in sequence using a slot die coater, wherein a plurality of wet layers can be applied before any of the individual layers are dried, gelled, cured and/or fused. The layers remain separate and distinct before and after drying, gelling, curing and/or fusing, and can be dried, gelled, cured and/or fused together or separately after wet on wet application to the substrate. The surface coverings may be decorative surface covering, including floor coverings.

Abstract: A highly filled surface covering, preferably a floor covering and more preferably a floor tile, includes a resin layer which has about 80% to about 95% by weight of filler and a chlorine-free binder. The binder includes a mixture of a maleic anhydride grafted polyethylene and a substantially linear ethylene/octene copolymer. The ratio of maleic anhydride grafted polyethylene and ethylene/octene copolymer is from about 1:5 to about 1:15 by weight. The preferred formulation for the binder includes a solid tackifier selected from the group consisting of a hydrocarbon resin having an ester moiety and hydrogenated aromatic resin.
