LOW-VISCOSITY POLYISOCYANATE COMPOSITION HAVING A HIGH FUNCTIONALITY AND THE PREPARATION METHOD THEREOF |
摘要 |
This invention relates to a polyisocyanate composition having a mean functionality of greater than 3, obtained by polycondensation of diisocyanate or triisocyanate monomers. The invention also relates to a reactive coating composition comprising the isocyanate composition defined above and a polyol having a hydroxyl number of between approximately 50 and approximately 250 and a number [lacuna] molar mass of between approximately 500 and approximately 15 000, said coating composition exhibiting a good pot life and a rapid rate of crosslinking at ambient temperature, to produce a crosslinked coating possessing good properties of surface hardness, of flexibility and of impact resistance. |
