The leveling of a floor polish composition can be improved by adding coumarin and/or a coumarin derivative thereto in an amount of from 0.05 to 10% by weight of polymer solids in said composition.

Process of improving the leveling of a floor polish composition

The appearance of a floor polish composition can be improved by use of a divalent copper ion crosslinking agent in an amount of from 50 to 5000 ppm based on polymer solids in said composition.

Process of improving the appearance of a floor polish composition

Metal-free polymer compositions are disclosed which contain selectively swellable emulsion polymer functionalities and which are cross-linked before film formation to an extent that still allows the polymers to form a film upon application, which film is removable with a stripper solution containing swellant for the polymer functionality. When the polymers are formulated into sacrificial coatings, the polishes produce detergent resistant and removable finishes.

Metal free emulsion polymers for high performance aqueous coatings

Acid-functional polymer is reacted with a transition metal compound at a temperature above the T.sub.g of the polymer to produce crosslinked polymer. The process produces a liquid polymer product that dries to a crosslinked film without the required presence of volatile ligands. Improved coating such as floor polishes are also disclosed.

Transition metal crosslinking of acid-containing polymers

Acid-functional polymer is reacted with a transition metal compound at a temperature above a T.sub.g of the polymer to produce crosslinked polymer. The process produces a liquid polymer product that dries to a crosslinked film without the required presence of volatile ligands. Improved coatings such as floor polishes are also disclosed.

A portable screed for working concrete and having an elongated screed plate which has a flat bottom bearing surface and a width sufficient to permit the screed to float on the concrete while the screed is being guided by an operator. For imparting uniform vibrations to the screed plate for tamping the concrete, the screed includes a stiffening brace extending substantially the length of the screed, a series of rigid, spaced cross supports secured to the brace, and a vibratory mechanism connected to vibrate the screed plate through the cross supports. A motor is mounted on the screed plate for operating the vibratory mechanism.

This invention is directed to floor polish vehicle compositions which yield floor polishes displaying improved durability. These floor polish vehicle compositions comprise a water insoluble emulsion copolymer containing acid functional monomer residues, transition metal ionic crosslinker, and a basic salt of an alkaline metal.

Floor polish composition having improved durability

This invention relates to self-leveling floor polish polymer compositions which may be formulated into floor polishes without requiring the use of additional leveling agents. These compositions are prepared by treating conventional floor polish emulsions or formulations with polyalkoxylated linear aliphatic alcohol as leveling agent.

Self-leveling floor polish compositions

This invention relates to a latex of internally plasticized polymer particles, low in viscosity although high in hydrophilic components and film forming at temperatures below the calculated Tg of the polymer. The polymer may be prepared by a multistage emulsion polymerization process. The first stage is highly water-swellable or water-soluble. The principal second or later stage is less hydrophilic and of higher Tg than the first stage and is polymerized in the emulsion in the presence of the first stage.
