20160052092 | AQUEOUS ALUMINUM BRAZING COMPOSITION - An aqueous aluminum brazing composition contains, as a binder resin, a water-soluble/dispersible polyurethane resin that exhibits a residual ratio of 60% by mass or less in a 400° C. heating environment and exhibits a residual ratio of 1.0% by mass or less in a 520° C. heating environment. | 02-25-2016 |
20160002379 | METAL FINE PARTICLE DISPERSANT, METAL FINE PARTICLE DISPERSION LIQUID, AND CURED FILM - A metal fine particle dispersant is obtained by reaction of a polymer (a) containing a first reactive functional group, an ionic group to be absorbed to metal fine particles, and a polyoxyalkylene side chain with a compound (b) containing a second reactive functional group to be bonded to the first reactive functional group and an active energy ray curable group to be cured by an active energy ray. A metal fine particle dispersion liquid containing the metal fine particle dispersant, metal fine particles, and a dispersion medium is prepared. The metal fine particle dispersion liquid is cured, thereby obtaining a cured film. | 01-07-2016 |
20150239071 | BRAZING COMPOSITION, HEAT EXCHANGER TUBE, AND HEAT EXCHANGER - A brazing composition contains 1 part by mass or more and 10 parts by mass or less of Zn powder, 1 part by mass or more and 5 parts by mass or less of Si powder, 3 parts by mass or more and 10 parts by mass or less of K—Al—F flux, 1 part by mass or more and 3 parts by mass or less of (meth)acrylic resin, wherein the mass ratio (Zn/Si) of Zn powder relative to Si powder is 1 or more and 5 or less. | 08-27-2015 |
