Anionic aliphatic polyester-polyurethane dispersion, cosolvent-free. Combination binder for the formulation of water-reducible soft-feel coatings. Properties / Applications: Bayhydrol® UH XP 2660 can be used as a binder in combination with hydrofunctional resins, preferably Bayhydrol® U 355 or U 475, in the formulation of highly flexible two-component polyurethane topcoats (e.g. in soft-touch coating systems). When crosslinking with e.g. Bayhydur® 3100, force drying (e.g. 30 - 45 min at 80 °C) yields films with good surface handle, very good resistance to solvents and very good hydrolytic stability.
