A resilient surface covering has a wear layer including a crosslinked aminoplast/polyurethane which is directly adhered to a vinyl support surface. The adhesion between the wear layer and support surface is improved by including at least 20% polyurethane by weight based on the total amount of aminoplast, polyurethane and epoxy resin in the wear layer composition, or by applying the wear layer composition to a gelled, but unfused vinyl support surface by fusing the vinyl support surface and curing the wear layer in a single step.

Aminoplast/polyurethane wear layer for PVC support surface

A seam cleaning paste, cream or liquid is disclosed, which comprises a hydrocarbon solvent and a finely divided inorganic powder. Treatment of the area near the seams of various types of floor coverings, especially highly stain resistant and soil resistant floor coverings, does not significantly change the appearance of the floor nor its resistance to soiling or staining. Yet it results in much improved adhesion of certain seam coaters subsequently applied to bridge the seam and prevent dirt from lodging therein. These creams do not exaggerate bubble formation in subsequently applied seam coaters and in fact, preferred embodiments help prevent such bubbles from forming.

Seam cleaning composition

Resilient surface coverings having improved scratch and stain resistance are disclosed in which a first top layer of a thermally-cured composition of a polyol component, an aminoplast component and an acid catalyst is adhered to a crosslinked or crosslinkable second layer material. A process to prepare such surface coverings is also disclosed.

The present invention relates to improved flooring materials and to a process for making said materials whereby a first layer on a support which is curable by actinic radiation is coated with a layer of a solution comprising water, acrylic acid, a suitable surfactant and, if desired, organic solvents. Upon irradiating the two layers, a tough, durable surface is formed having characteristics superior to those presently known in the art.
