PROCEDURE FOR OBTAINING ALLOPHANATES CONTAINING ISOCIANATE GROUPS |
| abstract |
Process for obtaining allophanates containing isocyanate groups, aliphatic and / or cycloaliphatically linked, by reaction of organic compounds bearing urethane groups with organic polyisocyanates bearing isocyanate groups aliphatic and / or cycloaliphatically linked, characterized in that the reaction is carried out in the presence of acids They form a mixed carbamic acid anhydride with aliphatic or cycloaliphatic isocyanates. |
