Claims (3)

1. Procédé de fabrication de composés contenant des groupes isocyanate bloqués et des groupes isocyanurate au départ de polyisocyanates et d'agents de blocage monofonc- tionnels contenant de l'hydrogène acide, caractérisé en ce qu'en premier lieu on convertit du 3 - isocyanatométhyl - 3,5,5 - triméthyl - cyclohexylisocyanate de manière connue en un mélange consistant en de l'isocyanurate contenant plus de 2 groupes isocyanate libres et en ce qu'on fait ensuite réagir ce produit intermédiaire avec de la diméthylcétoxime en tant qu'agent de blocage- monofonctionnel contenant de l'hydrogène acide à 50-1200C, en utilisant la diméthylcétoxime en des quantités pour que par équivalent de groupe NCO corresponde un équivalent de diméthylcétoxime.
2. Procédé selon la revendication 1, caractérisé en ce qu'on débarrasse le produit intermédiaire obtenu du polyisocyanate monomère puis en ce qu'on bloque ensuite de la manière décrite le polyisocyanate alors pratiquement exempt de monomère.
3. Mélange contenant des groupes isocyanate bloqués et des groupes isocyanurate, consistant en au moins 10% en poids d'un isocyanurate contenant
plus de 2 groups isocyanate avant le blocage avec de la diméthylcétoxime, au départ de 3 - isocyanatométhyl - 3,5,5 - triméthylcyclohexyl - isocyanate,
et éventuellement en une quantité pour compléter à 100% en poids du 3 - isocyanto- méthyl - 3,5,5 - triméthylcyclohexyl - isocyanate monomère bloqué avec de la diméthylcétoxime,

la teneur totale en groupes NCO non bloqués étant inférieure à 0,6% en poids.
