Title (EN) BLOCKED POLYISOCYANATES, PROCESS FOR PREPARING BLOCKED POLYISOCYANATES, AND THEIR USE AS CROSSLINKING AGENTS FOR POLYURETHANE POWDER CLEAR COATINGS
(FR) POLYISOCYANATES BLOQUÉS, PROCÉDÉ DE PRÉPARATION DE POLYISOCYANATES BLOQUÉS, ET LEUR UTILISATION COMME AGENTS DE RÉTICULATION POUR REVÊTEMENTS TRANSPARENTS PULVÉRULENTS À BASE DE POLYURÉTHANNE
Abstract:
(EN) The present invention relates to blocked polyisocyanates and a process for the synthesis of the blocked polyisocyanates as crosslinking agents for polyurethane powder coatings. Blocked polyisocyanates of the present invention after crosslinking with resins used for powder systems produce polyurethane coatings showing increased hydrophobicity, improved abrasion and scratch resistance than conventional polyisocyanates used for polyurethane powder clear coatings.
(FR) La présente invention concerne des polyisocyanates bloqués et un procédé de synthèse des polyisocyanates bloqués comme agents de réticulation pour des revêtements pulvérulents à base de polyuréthanne. Les polyisocyanates bloqués de l'invention, après réticulation avec des résines utilisées pour des systèmes pulvérulents, produisent des revêtements à base de polyuréthanne présentant une hydrophobicité accrue, une meilleure résistance à l'abrasion et aux rayures que les polyisocyanates classiques utilisés pour les revêtements transparents pulvérulents à base de polyuréthane.
