Abstract
Abstract THERMOSETTING ACRYLIC SOLUTION COATING COMPOSITIONS EXHIBITING MEWTONIAN FLOW CHARACTERISTICS ARE MODIFIED TO INCLUDE THIXOTROPIC AGENTS TO IMPART NON-NEWTONIAN FLOW CHARACTERISTICS TO THE COATING SOLUTION SO THAT THE SOLUTION WILL PERFORM BETTER WHEN ELECTROSTATICALLY SPRAYED. IN THIS WAY, AND WHEN EMPLOYING ELECTROSATIC SPRAY EQUIPMENT IN WHICH THE SOLUTION IS PUMPED TO THE ATOMIZING HEAD THROUGH A NARROW ORIFICE UN ORDER THAT SURGING WILL BE MINIMIZED WHEN THE ATOMIZNG HEAD IS RECIPROCATED, THE SPRAYED COATING DOES NOT BUBBLE AND CRATER.
