Abstract
Fluorinated polyisocyanates particularly suitable for the formulation of coating paints and compositions in the electronics industry, obtained by starting from a perfluoropolyether polyol having a functionality higher than 2 and from a diisocyanate, the resulting derivative having isocyanic functions being further condensed with a polyol in order to obtain a polyisocyanate with a high degree of functionality, and containing from 1.5% to 9% by weight of --NCO groups.
