  • Publication number: 20040055503
    Abstract: A method and solution to activate and metallize the surface of a fluorocarbon material, suitable for circuit boards is disclosed. The surface of fluorocarbon materials is both hydrophobic and oleophobic, and highly inert and repellent to oils, dyes, adhesive and coatings. The method of the present invention makes such fluorocarbon materials wettable with metallizing solutions and chemicals, and also bondable with adhesives and coatings. The method comprises contacting said fluorocarbon surface with a mixture comprising a cyclic amide, a quaternary ammonium compound, a cationic or nonionic surfactant, a glycolether and an organic acid.

  • Patent number: 6682594
    Abstract: A process for making a functional film by adding a magnesium alkoxide and a diethanolamine, which can dissolve or disperse the magnesium alkoxide, in an organic solvent followed by allowing hydrolysis of the magnesium alkoxide to proceed in a rate-controlling manner wherein the magnesium alkoxide is dissolved or dispersed in the organic solvent. Water is added in no more than a stoichiometric amount to the solution or dispersion partially to hydrolyze the magnesium alkoxide. The partial hydrolyzate solution is matured to grow magnesium oxide and/or magnesium hydroxide particles, resulting in a stable sol solution.
