Description

UNIPUR K 5520

Cationic PU dispersion

UNIPUR K 5520 is a transparent dispersion of low viscous PU binder and produces a clear, medium soft, tough-dry flexible film. It is used on polishable, pre-bottom and base coats applications from 50 to 200 g/l of mixture. It is advised for a wide range of full and corrected grain leathers, such as, upholstery, shoe-upper, fancy leathers and as well as splits. UNIPUR K 5520 yields excellent adhesion, improved fullness of grain and increase of flexometer values. The finished leather keeps its natural appearance. It can be used as adhesion promoter; penetration is optimised with the addition of water and methoxypropanol or similar solvents.
