| 摘要 |
Self-crosslinking paint binders, water-soluble upon protonation, containing biuret groups are described based on reaction products of blocked isocyanate groups containing aminoalkylation products of phenols with 0.1 to 1.0 moles, calculated on the hydrogen atoms at the urea groupings, of a semi-blocked diisocyanate. Optionally the phenolic hydroxy groups can be totally or partially reacted with epoxy compounds. The products are particularly suited for the formulation of high-grade, corrosion-resistant electrodeposition paints. |
