Abstract
Abstract COATING COMPOSITIONS IN WHICH THE VEHICLE IS BASED UPON AN INTEPOLYMER OF AN UNSATURATED CARBOXYLIC ACID AMIDE AND ONE OR MORE OTHER ETHYLENIC MONOMERS HAVE A GREATLY REDUCED TENDENCY TO FOAM WHEN THERE IS INCLUDED IN THE COMPOSITION A SMALL AMOUNT OF ALIPHATIC HYDROCARBON WAX MODIFIED WITH POLYALKYLENE OXIDE. SUCH NONFOAMING CHARACTERISTICS PERMIT THE APPLICATION OF THE COATING COMPOSITION BY ELECTROSTATIC SPRAY SYSTEMS OR FLOWCOATING TECHNIQUES WITHOUT COATING DEFECTS CAUSED BY BUBBLE FORMATION.
