    Abstract: Inorganic fillers such as silica balloons are used as a lightweight filler for resin moldings. But the specific gravity of these inorganic fillers is about 0.2 at most, so that there is a limit to reduction in weight. The foamed product of organic polymers is obtained as a lightweight substance, but it is hardly put to practical use because of its poor solvent resistance and thermal resistance.The microballoon of the present invention is produced by coating the surface of a hollow particle having the wall film of a thermoplastic high polymer with a thermosetting resin.The present invention provides a microballoon having excellent solvent resistance and thermal resistance as well as a very low specific gravity, and said microballoon is useful as a lightweight filler for resin moldings, aggregate for FRP, ingredient for paints, and the like.

  • Patent number: 4472229
    Abstract: Sheet products are made from amino-aldehyde, e.g. urea-formaldehyde, resin fibres in admixture with other non-cellulosic fibres, e.g. glass fibres, and optionally cellulosic fibres. Multiply products may be made from plies having the above constitution and plies of, for example, amino-aldehyde resin fibres, alone or in admixture with cellulosic and/or non-cellulosic fibres. The paper-like sheet materials may be used e.g. as filter papers.Laminated products may be made by pressing at an elevated temperature, a stack of plies of paper made from a mixture of amino-aldehyde resin fibres and another fibrous material, e.g. cellulosic fibres.

  • Patent number: 4456647
    Abstract: The invention relates to plastics mouldings, more particularly transparent plastics mouldings, which are finished with a coating of three successively stoved, chemically different layers, and to a process for producing the finish. The special finish considerably improves the scratch resistance, abrasion resistance, weathering resistance and yellowing resistance of the plastics surfaces without affecting the transparency of the plastics moulding. The first layer (primer layer) is produced from a hardenable acrylic resin and an aminoplast resin, the second layer from a thermoplastic acrylic resin, a plasticizer and a masked polyisocyanate and the third layer (cover layer) from at least one partially hydrolyzed organosilane, an .alpha.,.omega.-dihydroxy polydimethyl siloxane, a silica sol and at least one masked polyisocyanate as binder in the presence of a water-soluble organic or inorganic acid. The three-layer coating contains UV-absorbers, light stabilizers and, optionally, standard auxiliaries.

  • Patent number: 4448622
    Abstract: A composite polymeric film and a method for its use in forming and installing a very thin (<10 .mu.m) polymeric film are disclosed. The composite film consists of a thin film layer and a backing layer. The backing layer is soluble in a solvent in which the thin film layer is not soluble. In accordance with the method, the composite film is installed in a device in the same position in which it is sought to finally emplace the thin film. The backing layer is then selectively dissolved in the solvent to leave the insoluble thin film layer as an unbacked film. The method permits a very thin film to be successfully installed in devices where the fragility of the film would preclude handling and installation by conventional methods.

  • Patent number: 4436715
    Abstract: This invention relates to production of singlet oxygen and includes means and methods for storage and retrieval thereof as well as continuous production from ground state oxygen. With respect to storage and retrieval of singlet oxygen, certain aromatic acceptor compounds are oxidized to yield solid endoperoxides which, in turn, are decomposed to yield singlet oxygen and regenerate the acceptor. Continuous production of singlet oxygen occurs through irradiation of dye sensitizers with electromagnetic radiation causing activation thereof and excitation of flowing ground state oxygen.
