An aqueous alkyd resin coating composition, comprising (a) at least one alkyd resin as a dispersed phase; (b) an emulsifier based on styrenated phenols that have been converted into reactive surfactants by first reaction with one or more equivalents of an allyl glycidyl ether to provide pendant allyl groups and then oxyalkylated and (c) water. The invention also provides a method for preparing these aqueous alkyd resin coating compositions from solvent borne alkyd compositions.

Aqueous alkyd resin emulsions containing non-fugitive, reactive emulsifying surfactants

Waterborne coatings are described having an acceptable balance of properties both during the storage of coating, application and drying. The period in which irregularities in a freshly applied coating can be repaired without resulting in brush marks is referred to as the open time. Aqueous coatings generally employ dispersed high molecular weight polymers as binders. These binders often provide short open times when the coating is dried since the dispersed polymer particles tend to be immobilized quickly in the edge region of an applied coating. As a result, the viscosity of the coating increases rapidly, which leads to a limited window of workability. The instant invention provides additives that are not volatile but that will extend the time that the film is malleable after after it is applied without interfering with other attributes, such as the resistance of the coating to freezing while in the can prior to application.
