Bayhydrol® UH XP 2660 is an aliphatic polyester-polyurethane dispersion that is cosolvent-free. It is a combination binder for the formulation of water-reducible soft-feel coatings. This product has an Efflux time at 23°C, (4mmcup) of 10-30, a non-volatile content (1g / 1h / 125°C) of 39-41, and a pH (10% in water) of 6-8.
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.
