ABSTRACT:
This invention provides an aqueous coating composition, more particularly an aqueous floor finish composition, comprising water, at least one polymeric film forming agent, and a plasticizing agent, wherein the improvement comprises at least a portion of the plasticizing agent being at least one tertiary alkyl monocarboxylic acid having an average of from about 6 to 30 carbon atoms per molecule. Such compositions have one or more improved properties such as increased hardness as compared with the same compositions using only conventional plasticizers such as tributoxyethyl phosphate, improved wetting of the substrate by the composition during application, improved coating film leveling, improved multiple coat gloss development, and improved resistance to wear, black heel marking and scuffing.
