Superior Flux Superior No. 28 Silver Brazing Liquid Flux
Categories:	Metal; Nonferrous Metal; Solder/Braze Alloy
Material Notes:	Fluoride-Free Flux VOC-Free Excellent for eyeglass frames, jewelry, and precious metal applications. Description: Superior No. 29 is a Fluoride-Free and VOC-Free liquid brazing flux that contains borates and phosphates. It performs well on eyeglass frames, jewelry, and fine metal products. The flux exhibits excellent capillary action, drawing silver filler alloys into narrow joints. It exerts powerful scavenging action on most metal oxides, removing tarnish, scale, and other impurities to yield strong brazed joints. Applications: Superior No. 29 was formulated for the eyewear industry. However, the non-hazardous, non-toxic formulation makes it an ideal candidate for applications that do not require an active or concentrated flux. Information provided by Superior Flux
