Beschreibung
Zusammenfassung:	The invention relates to two-component (2K) polyurethane (PU) adhesives based on methylene diphenyl diisocyanate. The invention also relates to methods for the production of said adhesive and to the use thereof. Compared to 2K PUs based on toluene diisocyanate, the adhesives of the invention have lower viscosity and an improved worker safety profile. Los adhesivos de poliuretano (PU) de dos partes (2K) son descritos con base en difenil diisocianato de metileno. También se describen métodos de fabricación y uso. Comparados con los 2K Pus basados en diisocianato de tolueno, los adhesivos descritos tienen menor viscosidad y un perfil de seguridad para el trabajador mejorado. La présente invention porte sur des adhésifs au polyuréthane (PU) en deux parties (2K) à base de diphényle diisocyanate de méthylène. L'invention porte également sur des procédés de fabrication et d'utilisation. Comparativement aux adhésifs au polyuréthane 2K à base de diisocyanate de toluène, les adhésifs décrits ont une plus faible viscosité et un profil de sécurité amélioré pour l'ouvrier.
