摘要： An aqueous aluminum brazing composition containing an organic binder and zinc-based flux which prevents precipitation of the zinc-based flux having a large specific gravity while securing excellent brazeability. The thixotropic index of the brazing composition is adjusted to 1.01-1.20 by adding (meth)acrylic acid/(meth)acrylate copolymer emulsion to the brazing composition as a precipitation inhibitor in an amount of 0.03-1.50 wt% of 100 wt% of the brazing composition. Since the (meth)acrylic acid/(meth)acrylate copolymer emulsion is used as the precipitation inhibitor in a specific amount instead of other types of compounds used for powder-containing paint such as ultrafine particle silica, poly(meth)acrylate, or polyvinyl alcohol, precipitation of the zinc-based flux can be prevented without impairing brazeability.

摘要： A water-base aluminum-brazing composition comprising a zinc-base flux and an organic binder, wherein the zinc-base flux having a high specific gravity is inhibited from settling to thereby attain excellent brazing properties. The brazing composition is characterized in that the thixotropy value is adjusted to 1.01 to 1.20 by incorporating 0.03 to 1.50 wt% of a (meth)acrylic acid/(meth)acrylic ester copolymer emulsion as antisettling agent in 100 wt% of the composition. Unlike various compounds used in powder-containing coating materials such as ultrafine silica, poly(meth)acrylate salts, and polyvinyl alcohol, in the invention, a (meth)acrylic acid/ (meth)acrylic ester copolymer emulsion is used as antisettling agent in a prescribed amount, so that the settling of a zinc-base flux can be efficiently inhibited without an adverse effect on the brazing properties.
