Beschreibung
Zusammenfassung:	A low-tack aqueous binder composition is disclosed that includes at least 30.0% by weight of a polymeric crosslinking agent comprising at least two carboxylic acid groups, based on the total solids content of the binder composition; 10.0% to 50.0% by weight of a polyol having at least two hydroxyl groups, based on the total solids content of the binder composition; wherein the polyol comprises a sugar alcohol, an alkanolamine, pentaerythritol, or mixtures thereof; 1.5% to 15.0% by weight of an additive blend comprising one or more process additives, based on the total solids content of the binder composition; and 0 to 3.0% by weight of a silane coupling agent, based on the total solids content of the binder composition. The aqueous binder composition has an uncured pH between 4.0 and 7.0 and an uncured a peak tack force of no greater than 80 grams at 60% binder solids. L'invention concerne une composition de liant aqueuse à faible pégosité qui comprend au moins 30,0 % en poids d'un agent de réticulation polymère comprenant au moins deux groupes acide carboxylique, sur la base de la teneur totale en solides de la composition de liant ; de 10,0 à 50,0 % en poids d'un polyol ayant au moins deux groupes hydroxyle, sur la base de la teneur totale en solides de la composition de liant ; le polyol comprend un alcool de sucre, une alcanolamine, du pentaérythritol, ou des mélanges de ceux-ci ; de 1,5 % à 15,0 % en poids d'un mélange d'additifs comprenant un ou plusieurs additifs de traitement, sur la base de la teneur totale en solides de la composition de liant ; et de 0 à 3,0 % en poids d'un agent de couplage au silane, sur la base de la teneur totale en solides de la composition de liant. La composition de liant aqueuse a un pH non durci entre 4,0 et 7,0 et une force de pégosité maximale non durcie inférieure ou égale à 80 grammes à 60 % de solides de liant.
