POLYURETHANE DISPERSIONS OF LOW HARDNESS

The present invention relates to aqueous polyurethane dispersions comprising pentamethylene diisocyanate and to coatings obtainable therefrom. Said coatings, given a high density of urethane and urea groups, are softer than coatings that are obtained with polyurethane dispersions comprising other al...

More Information
Summary:The present invention relates to aqueous polyurethane dispersions comprising pentamethylene diisocyanate and to coatings obtainable therefrom. Said coatings, given a high density of urethane and urea groups, are softer than coatings that are obtained with polyurethane dispersions comprising other aliphatic diisocyanates, for example hexamethylene diisocyanate.
