  • Phenol-free decorative laminates and method of producing the same
    Patent number: 7244504
    Abstract: The invention relates to phenol-free decorative laminates, in the form of sheets, such as HPL, CPL and LPL, using multilayer carrier materials in which no phenol resins are used for impregnation and which are therefore toxicologically safe, have a neutral odor and are more economical in their production. The impregnating resin system used is a urea/melamine/formaldehyde resin which was processed exclusively in an aqueous reaction medium and to which a polymer dispersion was added, the impregnating resin having been prepared in a first stage in the pH range from 7.0 to 8.5 and in a second stage in the pH range from 4.0 to 6.0. Finally, this resin batch is neutralized, added to the carrier material and pressed with the latter.
