Abstract
Selon l'invention, on fait réagir les polyisocyanates organiques avec un mélange contenant au moins un mono-alcool aliphatique ou cycloaliphatique primaire, secondaire ou tertiaire, au moins une mono- ou poly-amine portant au moins un groupe amino primaire aliphatique, cycloaliphatique ou araliphatique et, le cas échéant, de l'eau ou un composé libérant de l'eau. Le procédé selon l'invention permet de parvenir à des polyisocyanate-biurets à faible viscosité, peu colorés et stables.
