ABSTRACT:
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.
