AQUEOUS COATING COMPOSITIONS EXHIBITING INCREASED OPEN TIME WITH REDUCED LEVELS OF VOLATILE ORGANIC COMPOUNDS

摘要

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.
