Surfactants for aqueous based coatings
Abstract:
Disclosed are aqueous coating compositions comprising a branched alkyl alcohol ethoxylate oligomer of formula where m is 1 to 3 and where n is an average number such that Mn is from about 1030 to about 2400, at least one latex polymer and water. The compositions also preferably comprise at least one pigment such as titanium dioxide. The compositions are for instance architectural latex paints. The compositions are for instance free of alkyl phenol ethoxylate (APE) surfactants and are low or zero VOC (volatile organic compounds). The compositions are provided effectively long open film times with excellent leveling properties.
