Patent number: 4894413Abstract: Improvement in the method for preparing resin compositions for use as a laminate material in printed wiring boards wherein the resin composition is formed by mixing an epoxy-anhydride prepolymer with maleated polybutadiene and a suitable solvent. The improvement involves preparing the epoxy-anhydride prepolymer using a two step procedure instead of a single step. The two step procedure prevents uncontrolled exothermic reactions from occurring during preparation of commercial quantities of the epoxy-anhydride prepolymer and increases the versatility of the process since different anhydrides can be used in each of the two steps.Type: GrantFiled: October 9, 1987Date of Patent: January 16, 1990Assignee: Hughes Aircraft CompanyInventors: Ephraim H. Catsiff, William E. Elias

Patent number: 4871807Abstract: Water-dilutable paint binders for the formulation of ecological stoving paints containing only minor quantities of organic solvents are described. The binders are partial condensation products of (A) a polycondensation, polymerization, or polyaddition resin as the film-forming polycarboxy compound (PC-component), and (B) an epoxy resin amine adduct (PH-component) carrying hydroxy groups and being water-insoluble under normal processing conditions. The products afford improved corrosion resistance and are particularly suited for the formulation of primers, intercoats (primer surfacers), and single coat paints.Type: GrantFiled: December 23, 1987Date of Patent: October 3, 1989Assignee: Vianova Kunstharz, A.G.Inventors: Werner Staritzbichler, Gert Dworak, Wolfgang Daimer
