Abstract

La presente invención está relacionada con una composición de dos componentes adecuada para proporcionar una preparación de recubrimiento de la cual se puede obtener una capa curada con el fin de proteger la superficie de materiales contra el impacto perjudicial de los efectos de la intemperie y/o de la corrosión. La composición de dos componentes comprende un primer componente C1 que comprende (a) una poliolefina que tiene una estructura polimérica que consiste en (a-i) unidades de repetición derivadas de un monómero olefínicamente insaturado que tiene 4 átomos de carbono y, opcionalmente, (a-ii) un grupo hidrocarburo L que tiene 5-20 átomos de carbono en una posición no terminal de dicha estructura polimérica, en donde dicha estructura polimérica tiene grupos funcionales seleccionados de grupos hidroxilo y grupos amina en sus extremos de cadena; y (C2) un segundo componente que comprende una preparación que comprende (b1) un poliisocianato que tiene 2 o más grupos isocianato y/o (b2) un producto de reacción que tiene grupos isocianato obtenidos por reacción de dicho poliisocianato que tiene 2 o más grupos isocianato (b1) y (b2a) una poliolefina que tiene una estructura polimérica que consiste en (b2a-i) unidades de repetición derivadas de un monómero olefínicamente insaturado que tiene 4 átomos de carbono y, opcionalmente, (b2a-ii) un grupo hidrocarburo que tiene 5-20 átomos de carbono en una posición no terminal de dicha estructura polimérica, en donde dicha cadena de polímero tiene grupos funcionales seleccionados de grupos hidroxilo y grupos amina en sus extremos de cadena.
