Pre-flux coating for the manufacturing of components by brazing, in particular manufacturing of heat exchangers of aluminium components including one or more fluxes and filler material. The coating is composed of one ore more fluxes in the form of potassium aluminum fluoride K1-3AIF4.6, potassium trifluoro zincate, KZnF3, lithium aluminum fluoride Li3AIF6, filler material in the form of metallic Si particles, Al—Si particles and/or potassium fluoro silicate K2S1F6, and additive in the form of alumminium oxide and/or other suitable oxide or material forming a post braze ceramic layer, and further including solvent and binder containing at least 10% by weight of a synthetic resin which is based, as its main constituent, on methacrylate homopolymer or methacrylate copolymer. |
