Title (EN) TWO-COMPONENT (2K) CLEARCOAT AND METHOD TO COAT A SUBSTRATE WITH THE TWO -COMPONENT (2K) CLEARCOAT HAVING ENHANCED VISUAL APPEARANCE
(FR) COUCHE TRANSPARENTE À DEUX CONSTITUANTS (2K) ET PROCÉDÉ POUR REVÊTIR UN SUBSTRAT AVEC LA COUCHE TRANSPARENTE À DEUX CONSTITUANTS (2K) AYANT UN ASPECT VISUEL AMÉLIORÉ
Abstract:
(EN) A two-component clearcoat composition contains a first component comprising a hydroxyl-functional resin; and a second component comprising a crosslinking agent which is a first isocyanate resin which is unblocked; wherein at least one of the first component and the second component further comprises a blocked isocyanate resin which is a reacted form of a second isocyanate resin and a blocking agent; and wherein the first isocyanate resin and the second isocyanate resin are capable of reacting with the hydroxyl-functional resin to form a crosslinked coating. A substrate coated with the clearcoat composition exhibits improved visual appearance to the coated substrate, such as reduced orange peel and an increased balance value.
(FR) La présente invention concerne une composition de revêtement transparent à deux constituants contenant un premier constituant comprenant une résine à fonction hydroxyle ; et un second constituant comprenant un agent de réticulation qui est une première résine d'isocyanate qui est débloquée ; le premier constituant et/ou le second constituant comprenant en outre une résine isocyanate bloquée qui est une forme issue de la réaction d'une seconde résine d'isocyanate et d'un agent de blocage ; la première résine d'isocyanate et la seconde résine d'isocyanate étant aptes à réagir avec la résine à fonction hydroxyle pour former un revêtement réticulé. Un substrat revêtu de la composition de revêtement transparent confère un aspect visuel amélioré au substrat revêtu, tel qu'un aspect peau d'orange réduit et une valeur d'équilibre accrue.
