| abstract |
The invention concerns a composition, characterised in that it comprises by successive or simultaneous addition: an isocyanate at least partially masked having a glass transition temperature (Tg) of at least 20 DEG C, advantageously of at least 40 DEG C and a release rate at 120 DEG C of at most 5 %; a polyol with the following characteristics: a glass transition temperature (Tg) of at least 40 DEG C approximately, advantageously of at least 50 DEG C approximately; a hydroxyl value of at least 10 mg/g, advantageously, 15 mg/g; a mean molar mass Mn at least equal to about 1000, advantageously to 2000 g/mol. The invention is applicable to paints. |
