| titleOfInvention | Aqueous two-component PUR coating systems |
| abstract | Reaction of monomer-deficient polyisocyanates with monofunctional polyethylene oxide polyether alcohols under allophanate production conditions gives a new water dispersible mixture of high isocyanate functionality. A new coating composition comprises: (A) 30-99 wt.% of aqueous, hydroxy, and/or amino-functional resin dispersion; (B) 1-70 parts by weight of a water dispersible resin component; and (C) 0-60 parts by weight of conventional lacquer technology adjuvants and additives. B is a water dispersible polyisocyanate mixture based on aliphatic, cycloaliphatic, araliphatic, and/or aromatic diisocyanate which has (a) a mean isocyanate functionality of at least 2.0; (b) an isocyanate group content (calculated as NCO; molecular weight 42) of 5.0-25 wt.%; and (c) a content of ethylene oxide units bonded inside the polyether chains (calculated as C2H4, molecular weight = 44) of 2-50 wt.%, where the polyether chains contain a statistical mean of 5-35 ethylene oxide units, and the polyether chains are bonded, via allophanate groups, to at least 60 mol% polyisocyanate molecules synthesized from at least two diisocyanates. An Independent claim is included for preparation of the composition by mixing components A, B, and optionally C so that the mixture contains 0.1-3.0 component B isocyanate groups for each OH or amino group of component A. |
