Title (EN) IMPROVED WEATHER RESISTANT POLYURETHANE ELASTOMER
(FR) ELASTOMERE POLYURETHANNE AMELIORE RESISTANT AUX INTEMPERIES
Abstract:
(EN) This invention relates to polyurethane elastomers and to a process for their production. These elastomers comprise the reaction product of a (cyclo)aliphatic isocyanate component having an NCO group content of about 20 to about 45%, with an isocyanate-reactive component comprising one or more low unsaturation polyether polyols, a low molecular weight organic compound containing two hydroxyl groups and which is free of amine groups, and, optionally, one or more organic compounds having a molecular weight of about 200 to about 500, a hydroxyl functionality of 3 to 4 and comprising an amine-initiated polyether polyol.
(FR) La présente invention concerne des élastomères polyuréthannes et leur procédé de préparation. Ces élastomères comportent le produit réactionnel d'un constituant isocyanate (cyclo)aliphatique comprenant une teneur en groupe NCO d'environ 20 à environ 45 % avec un constituant réactif à l'isocyanate comprenant un ou des polyols de polyéther à faible insaturation, un composé organique de faible poids moléculaire contenant deux groupes hydroxyles et qui est exempt de groupes amines, et, éventuellement, un ou des composés organiques ayant un poids moléculaire entre environ 200 et environ 500, une fonctionnalité hydroxyle de 3 à 4 et comprenant un polyol polyéther à base amine.
