The high gloss of vinyl composition floor coverings having a no-wax coating is maintained by using a cleaner consisting essentially of an aqueous emulsion polymerized alkali-soluble terpolymer having an average molecular weight of about 23,000, the terpolymer being an addition polymer based on about 51% by weight methyl methacrylate, 31% by weight butyl acrylate, and 18% by weight acrylic acid; a mixture of 50% by weight of the reaction product of 1 mole of coconut oil to 2 moles diethanolamine and 50% by weight of the reaction product of 1 mole dodecylbenzenesulfonic acid to 1 mole diethanolamine; an organic solvent; an aqueous ammonia solution; and water. Before being used as a cleaner the cleaner is preferably diluted to between about 0.5 to 0.10 percent solids.

Cleaning composition for no-wax vinyl composition floor covering

A process for flatting a glossy polyurethane surface is disclosed. The process involves the steps of forming a wear layer on a carrier member, such comprising a polyurethane-forming composition. The coated carrier member is then treated with vaporous water at a temperature below the dew point of the vaporous water so that a film of liquid water is deposited on the surface of the coating. The coating with the liquid water deposited thereon is then cured to a tack free state and then subjected to elevated temperatures where the curing of the polyurethane coating is completed.
