Zusammenfassung:22nl4 An aqueous latex coating composition and method of making an aqueous latex coating composition that comprises at least one oligomeric ethylene glycol derivative having the structure RO-(CH-CH-O-)-H, at least one latex polymer, and water, wherein R is H or C-Calkyl and preferably H, and n is from 3 to 9, preferably from 3 to 8, and more preferably from 3 to 6. The oligomeric ethylene glycol derivative functions as both a coalescing solvent and freeze-thaw stabilizer without contributing to the VOC content of the composition.
