摘要

High-functionality compositions based on fluorinated and silanized polyisocyanates, prepared by reacting a hydroxy-terminated perfluoropolyether having an average molecular weight ranging from 500 to 7000 and a silico-carbinol having an average molecular weight ranging from 500 to 7000, with an organic diisocyanate and a polyol having a functionality of at least 3. Varnishes containing said compositions based on fluorinated and silanized polyisocyanates, having a high functionality.
