  • Resin compositions based on phenolic resins
    Patent number: 5004789
    Abstract: Compositions of phenolic resins, for example, phenol formaldehyde resins, containing an additive of triethanolamine borate or an amine/oxygen-containing boron derivative mixture, e.g., triethanolamine and boric anhydride, are particularly useful for the manufacture of prepeg mats.

  • Manufacture of creep-free prepregs based on phenolic resins
    Patent number: 4962166
    Abstract: In the manufacture of creep-free prepregs based on phenolic resins of the resole type, the reinformcing agents are impregnated with an essentially solvent-free mixture of a phenolic resin and a viscosity controlling amount up to 60% by weight of the resin of an alkali metal metaborate or an alkaline-earth metaborate or a mixture thereof. The resultant compression molded articles exhibit improved strengths.

  • Laminates having an improved finishing layer
    Patent number: 4599212
    Abstract: Reinforced phenolic laminates are provided with a finishing coat of a butylated phenol-formaldehyde resin, thereby removing surface irregularities. The finishing coat can be mass-pigmented to the desired color, thereby obviating the necessity of any additional color-containing coatings.

  • Hardening phenol-formaldehyde resols in the presence of aniline
    Patent number: 4555544
    Abstract: In a process for hardening phenol-formaldehyde resol resins, comprising conducting the hardening of the resins with an acidic solution of water and/or an organic solvent having dissolved therein an aromatic sulphonic acid and/or concentrated sulphuric acid, the improvement comprising the hardening in the presence of aniline added to the phenolic resin beforehand in a quantity of between about 0.5 and 2% relative to the weight of the phenolic resin whereby the pot life is extended and the cure time is satisfactory, the resultant products being especially useful as prepegs.
    Type: Grant

    Date of Patent: November 26, 1985
    Assignee: Societe Chimique des Charbonnages CDF Chimie, S.A.
    Inventors: Nicolas Meyer, Michel Cousin
  • Laminates of improved fire resistance
    Patent number: 4365001
    Abstract: There are obtained laminates of improved fire resistance comprising a substrate of reinforced phenolic resin, directly coated on at least one side thereof with a surface layer of a furan resin, and bonded to the outer surface of the furan resin a "gel-coat" of an unsaturated polyester resin, wherein the furan resin contains boron in sufficient amounts to impart an improved fire resistance to the laminates as compared to the fire resistance of the outer surface gel-coat. The boron is introduced as boric anhydride by use of a substantially anhydrous boric anhydride hardener solution to harden the furan resin.
