Abstract: The present invention provides an aqueous polyurethane dispersion (PUD) comprising an amorphous polyester having a glass transition temperature (Tg) as determined by differential scanning calorimetry of less than ?30° C.; wherein the aqueous polyurethane dispersion (PUD) has a glass transition temperature (Tg) as determined by differential scanning calorimetry (DSC) of 0° C. to 20° C. and a hard block content of greater than 50%. Coatings, adhesives, sealants, paints, primers and topcoats, made from the inventive aqueous polyurethane dispersion (PUD) are particularly suited for use on wood surfaces including floors, doors, window frames, door frames, picture frames, window shutters, window surrounds, railing, gates, pillars, arbors, ladders, shelves, furniture, stairs, cabinetry, decks, docks, boats, pergolas, trellises, gazebos, posts, fencing, cladding, and siding and for concrete, cement, stone, or brick substrates such as floors, pipes, walls, pavers, vaults, blocks, tiles, and roof tiles.
