Title (EN) POLYURETHANE DISPERSIONS OF LOW HARDNESS
(FR) DISPERSIONS DE POLYURÉTHANE PEU RIGIDES
Abstract: front page image
(EN)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.
(FR)La présente invention concerne des dispersions aqueuses de polyuréthane comprenant du diisocyanate de pentaméthylène (PDI) et des revêtements pouvant être obtenus à partir de celles-ci. La densité des groupes uréthane et urée dans ces revêtements étant élevée, ceux-ci sont plus souples que les revêtements obtenus avec des dispersions de polyuréthane comprenant d'autres diisocyanates aliphatiques, par exemple du diisocyanate d'hexaméthylène.
