In addition to acting as effective plasticizers, certain acid, carboxylate and hydroxyl-functional liquid polyesters that are liquid at 25o C. can be used as at least partial replacements for the more volatile organic compounds conventionally used as coalescents and/or property enhancers in aqueous film-forming compositions. The resultant compositions exhibit reduced VOC values relative to prior art compositions exhibiting comparable levels of application and coating properties.
En plus de servir de plastifiants efficaces, certains polyesters liquides à fonctionnalité acide carboxylate et hydroxyle, qui sont liquides à 25°C peuvent être utilisés en tant que produits de remplacement partiels des composés organiques plus volatils classiquement utilisés en tant qu'agents coalescents et/ou agents améliorant les propriétés dans des compositions filmogènes aqueuses. Selon linvention, les compositions résultantes présentent des valeurs réduites de composés organiques volatils (VOC) par rapport aux compositions de l'état de la technique présentant des taux comparables de propriétés d'application et de revêtement.
