Abstract

Procédé de préparation de polyisocyanates portant des groupes biuret par réaction de polyamines portant deux groupes amino primaires aliphatiques ou cycloaliphatiques avec des polyisocyanates organiques exempts de groupes biuret dans des proportions relatives correspondant à un rapport molaire NH2 /NCO de 1 : 5 à 1 : 100. On fait réagir les polyamines à l'état de vapeurs avec les polyisocyanates chauffés à une température de 100 à 250 degrés C. Les polyisocyanates-biurets préparés conformément à l'invention servent à la préparation de vernis stables à la lumière et aux influences climatiques.
