Zusammenfassung:In addition to acting as effective plasticizers, dibenzoates of diethylene and dipropylene glycols in combination with at least one of the corresponding monoesters within a specified concentration range are unique in their ability to extend the open time exhibited by aqueous polymer compositions, and are thereby capable of replacing at least a portion of more volatile organic compounds (VOC.'s) such as diols, glycols and esters of mono-and dihydric alcohols and benzoates of monohydric alcohols that are typically used as coalescents for these polymer compositions.
