Abstract
Abstract A storage stable water-based paint comprising a solid silicone resin and an ammonium salt of a drying oil modified acrylic copolymer provide a coating for barbecue grills and other appliances that are subjected to temperatures as high as 1300° F. A smooth and continuous coating remains on the metal after burning off of the acrylic resin and firing of the metal at 1300° F. The paint is redispersible and may be drawn down to 1.5 mils after storage at 120° F. for more than 3 months when the pH is at least about 8.
