| titleOfInvention | Polyimide composition for fixing metallic sheets |
| abstract | A fixing composition comprises a polyimide precursor, and organic solvent, optionally an epoxy resin, e.g. a bisphenol A type, optionally with a heat-activated hardener, and possibly other additives. The precursor is preferably a polyamic acid synthesized from an aliphatic tetracarboxylic dianhydride or lower alkyl ester or halide thereof and an organic diamine optionally with a triamine or tetramine. n<??>A sheet 0.5 to 5 mm thick of a powdered metal alloy, e.g. a multi-component eutectic alloy and a synthetic resin binder composition, e.g. an acrylic copolymer and an adhesive component, is placed on a metal substrate, e.g. of steel; a molded film or coated layer of 5-50 mu m thickness of the fixing composition is placed therebetween. The assembly is heated and an adhesive force is exerted due to hardening of the precursor; heating is continued to sintering temperature, e.g. 1,000 to 1,150 DEG C, at which the precursor is carbonised to a residual C content of 10 to 60 wt%, and the alloy sinters to the substrate. n<??>The alloy sheet is adhered firmly to the substrate before and during sintering. |
