Bayhydrol® UH 2305 

Bayhydrol® UH 2305 is an aliphatic, anionic/non-ionic polyester-polyurethane dispersion that is a shear-stable combination binder used in the formulation of flexible two-component polyurethane top coats with pleasant handle, e.g. soft-feel systems. This product has an efflux time at 23°C, (4mmcup) of 11-18, a non-volatile content (1g / 1h / 125°C) of 39-41, and a pH value of 6.5-8.5.

Bayhydrol® UH 2305 can be used as a combination binder with hydroxy-functional resins, primarily Bayhydrol® U XP 2428, in the formulation of highly flexible two-component polyurethane top coats, e.g. soft-feel systems. After crosslinking with, for example, Bayhydur® 3100, force-drying (e.g. 30 - 45 min at 80 °C) yields films with a pleasant handle and good resistance to abrasion and water.
