The present invention provides an aqueous polyurethane dispersion (PUD) comprising an amorphous polyester having a glass transition temperature (T) as determined by differential scanning calorimetry of less than &#x2212;30&#xb0; C.; wherein the aqueous polyurethane dispersion (PUD) has a glass transition temperature (T) as determined by differential scanning calorimetry (DSC) of 0&#xb0; C. to 20&#xb0; 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) pass detergent resistance testing according to the American Architectural Manufacturers Association's standard, AAMA 615-13, have a pencil hardness according to ASTM D3363 of at least 3H, and are particularly suited for use on low surface energy substrates such as vinyl and other surfaces including floors, windows, doors, window frames, door frames, window shutters, railing, gates, pillars, arbors, pergolas, trellises, gazebos, posts, fencing, pipes and fittings, wire and cable insulation, automobile components, credit cards, and siding.

One component polyurethane dispersion for vinyl windows and other substrates

The present invention relates to polyurethane/ureas wherein the polyurethane/ureas contain 0.5 to 6% by weight, based on the weight of the polyurethane/ureas, of alkoxysilane groups (calculated as Si, MW 28), which have been incorporated by the reaction of isocyanate groups with a dihydroxy compound containing urea and alkoxysilane groups, and wherein the polyurethane/ureas optionally contain hydrophilic groups and are optionally dispersed in an aqueous medium. The present invention also relates to a process for preparing these polyurethane/urea and to their use for preparing coatings.

Polyurethane/urea containing pendant alkoxysilane groups

The present invention is directed to a waterborne, UV-curable polyurethane emulsion and the use thereof in producing soft touch coatings. The emulsion is prepared by a) reacting specified hydroxy-functional components with di- and/or polyisocyanates, b) forming a dispersion of the resultant product with water and reacting the dispersion with amine functional materials.

Polyurethane/ureas including hydrophilic moieties and alkoxysilane groups of formula (I)&#x2014;X&#x2014;CO&#x2014;NR&#x2014;Y&#x2014;Si&#x2014;(Z)&#x2003;&#x2003;(I)where X is O or NR; Ris H, C-Calkyl, substituted C-Calkyl, cycloalkyl, aryl or benzyl; Y is C-Clinear and branched alkylene; and Z is an organic group inert to isocyanate groups below 100&#xb0; C. At least one Z group is an alkoxy group of 1 to 4 carbon atoms. The polyurethane/urea can be in an aqueous dispersion, which can be used to prepare coatings. The dispersion is prepared by
