Przedmiotem zgłoszenia jest sposób wytwarzania blokowanych poliizocyjanianów jako środków sieciujących do poliuretanowych powłok proszkowych. Blokowane poliizocyjaniany otrzymane tym sposobem po usieciowaniu żywicami stosowanymi do systemów proszkowych dają powłoki poliuretanowe o zwiększonej hydrofobowości, lepszej odporności na ścieranie i zarysowanie niż wyroby sieciowane typowymi poliizocyjanianami stosowanymi do farb i lakierów proszkowych.The subject of the application is a method for producing blocked polyisocyanates as crosslinking agents for polyurethane powder coatings. Blocked polyisocyanates obtained in this way after crosslinking with resins used for powder systems give polyurethane coatings with increased hydrophobicity, better resistance to abrasion and scratching than products crosslinked with typical polyisocyanates used for powder paints and varnishes.
