Abstract

La presente invencion se refiere a una composicion de recubrimiento para la preparacion de un recubrimiento de poliurea que contiene: a) un prepolímero de NCO que contiene grupos isocianato unidos aromáticamente b) una aldimina que corresponde a la formula X1-[N=CHCH(R1)(R2) donde X representa un grupo orgánico que tiene una valencia de n y so obtiene por separacion de grupos amino de una poliamina orgánica cíclica que tiene grupos amino (ciclo) alifáticamente unidos, R1 y R2 pueden ser idénticos o diferentes y representan grupos orgánicos que son inertes para los grupos isocianato a una temperatura de 100 degree C o menos, o R1 y R2 junto con el átomo de carbono beta forman un anillo cicloalifático o heterocíclico, y n representa un entero que tiene un valor de al menos 2, en el que los componentes a) y b) están presentes en cantidades suficientes para proporcionar una relacion de equivalentes de grupos isocianato a grupos aldimina de aproximadamente 1,0:0,7 a 1,0:0,1.
