Abstract
A flux coating composition may include a composition paste including an elastomer solution mixed with a flux powder or a flux paste. When the composition is heated during a brazing operation, the composition yields no metal oxides and ≦50 ppm of carbon, ash, fumes, smoke, or other by-product contaminants. The flux may include a binder with an acrylic resin and a plurality of synthetic rubber compounds.
