Definitions

  • compositions for high temperature resistant film coatings are provided.
  • the present invention relates to compositions based on modified inorganic polycondensation products and their use for coating films, in particular based on cellulose triacetate, to increase the temperature resistance, the films coated in this way and their use as release films in the production of thermosetting laminates.
  • prepregs are laminated to copper foil using pressure and temperature.
  • the prepregs consist of reinforcing materials (usually glass fiber fabrics) impregnated with reactive resins (epoxides, imides, phenols, cyanic acid esters), the resins being partially crosslinked in order to maintain a certain consistency of the material.
  • reactive resins epoxides, imides, phenols, cyanic acid esters
  • the reactive resins are cured and form a firm bond with the reinforcing material and the copper foil.
  • the lamination process is usually done in stacks, with several sheets being laminated at the same time. This requires the use of release film between the individual pairs of laminates.
  • the separating film has to withstand the applied pressures and temperatures to such an extent that the resulting plates have no problems after lamination can be separated from each other and no components of the film remain on the plates.
  • polyester films PET, PEN
  • triacetate films meet the requirements described in the range of 160 to 180 ° C with regard to their hydrophobicity and temperature stability. That is why they are mainly used for the production of prepregs themselves. For modern lamination processes and the unlimited use of the available reactive resins, higher temperatures up to over 200 ° C are required. Untreated triacetate films are no longer suitable for this. Embrittlement occurs because any plasticizer that is present escapes from the film and the polymer itself is denatured. On the one hand, the hydrophobicity of the material is lost, on the other hand, the cohesion of the film is destroyed and it partially sticks to the surfaces to be separated.
  • the film is surface-sealed in such a way that, despite the effect of temperature, the film properties are largely retained and the surface-sealing layer itself, with its hydrophobicity, takes on the required separating effect.
  • JP-A-11/020086 describes a PEN-based release film with a two-layer structure, which consists of a primer (acrylate ester copolymer latex and methyltrimethoxysilane) and a silicone layer.

  • a silicone layer a two-layer structure, which consists of a primer (acrylate ester copolymer latex and methyltrimethoxysilane) and a silicone layer.
  • a primer acrylate ester copolymer latex and methyltrimethoxysilane
  • silicone layer unsuitable for use as separating foils in the production of laths, since parts of these silicone compounds pass over to the copper foil when they come into contact under high temperatures and pressures because they are not firmly anchored in the layer structure. This can lead to serious problems in the subsequent steps of circuit board manufacture and functional failures in the later use of the circuit board.
  • Heat-resistant release films for the production of PVC films with coating compositions from a network of amino and glycidyl-modified SiO 2 sols are described in JP-A-02/214624.
  • these networks are unsuitable for use in the production of printed circuit boards since even with equimolar use of the active groups (amino, glycidyl groups) a complete conversion does not take place in the layer.
  • Hydrophobic and separating properties can also be achieved by adding fluorine-containing components.
  • EP-A-0 641 843 describes perfluorinated alkylsilanes as constituents of water- and oil-repellent layers.

An additional polymerization step (photopolymerization) is required to achieve the layer strength.
  • Fluorine-containing coating compositions can only be applied to triacetate film to a limited extent. Experience has shown that if the proportion of fluorine in the inorganic condensation product is greater than 3 mol%, based on the starting products of the condensation, coating on triacetate film is not possible due to wetting problems.
