Abstract: The floor covering of the present invention has a wear layer and/or seam coater which is a high T.sub.g urethane composition. While most floor covering urethanes have a T.sub.g of from 18.degree. C. to 23.degree. C., the T.sub.g of the present urethane is above about 40.degree. C., and preferably from about 48.degree. C. to about 55.degree. C. The T.sub.g of the prior art has been increased by altering the composition of the aromatic acid based polyester polyols used in the prior art moisture curable prepolymers. By raising the precursor polyol to dicarboxylic acid ratio, the polyester polyols produced have lower equivalent weights. This alone results in a polyurethane-urea of higher T.sub.g at a given alicyclic diisocyanate to polyester equivalent ratio. However, increases in the T.sub.g may also be obtained by replacing some or all of long chain flexible polyol precursors (e.g. triethylene glycol) with shorter and/or less flexible polyol precursors. The high T.sub.g improves stain resistance.

Abstract: The seam of a surface covering product, having an exposed surface which is the reaction product of a protective coating composition including an aminoplast and a polyol, is coated with a seam coating composition including a cyanoacrylate monomer and a plasticizer. The preferred monomer is methyl 2-cyanoacrylate, ethyl 2-cyanoacrylate or methoxy ethyl 2-cyanoacrylate. The preferred plasticizer is dibutyl phthalate. The seam coating should have a viscosity of about 100 CPS. An accelerator may be applied to the uncured seam coating.

Abstract: A non-skid decorative plastic floor covering comprised of a decorative plastic base having a plurality of slip-resistant elements positioned on the base with a clear or translucent wear layer overlying the slip-resistant elements and the exposed intervening base. The slip-resistant elements comprise particles, preferably inorganic and rounded, embedded in a cured plastic matrix, the particles being distributed throughout the matrix in a substantially abutting relationship with the upper-most layer of particles protruding from the matrix such that the protruding particles impart a rough, irregular non-skid surface texture to the wear layer overlying the slip-resistant elements.
