  • Patent number: 9733425
    Abstract: A process for producing an optical fiber including a glass fiber, a primary resin coating layer which covers the periphery of the glass fiber, and a secondary resin coating layer which covers the periphery of the primary resin coating layer, wherein the primary resin coating layer is formed by curing a curable resin composition which includes one or more oligomers, one or more monomers, and a reaction initiator, the curable resin composition containing a one-end-capped oligomer in an amount of 30% by mass or larger based on all the oligomers. The optical fiber produced by this production process does not deteriorate in low-temperature transmission loss, because the primary resin coating layer is inhibited from generating voids even when having a low Young's modulus.

  • Patent number: 8053488
    Abstract: An ambient temperature curable hydrophilic PU oligomer includes a PU pre-polymer having a hydrophilic center group and a curable terminated group. The ambient temperature curable hydrophilic PU oligomer includes the moisture-curable hydrophilic PU oligomer such as isocyanate-terminated PU pre-polymer and free-radical curable hydrophlic PU oligomer. The isocyanate-terminated PU pre-polymer is synthesized by mixing at least one multi-isocyanate, at least one polyol and one or more diol monomer with hydrophilic group. The acrylate-terminated PU oligomer is synthesized by adding 2-hydroxyethyl methacrylate (HEMA) into the isocyanate-terminated hydrophilic PU pre-polymer. Either acrylate- or isocyanate-terminated PU oligomer can be applied on a textile or a glass surface with a thin-layer coating technology. The curing reactions of these hydrophilic thin-layer coatings are carried out with moisture or UV-radiation, respectively, at ambient temperature.

  • Patent number: 8048979
    Abstract: The present invention involves the design of a radiation curable organic pre polymer resin material based on urethane acrylic linkage synthesized from the natural renewable resource cardanol or a derivative thereof, for coating application. These new molecules have a faster and better curing rate compared to the starting renewable resource—cardanol. This is brought about by the hydrogen bonding of the urethane linkage which leads to a pre organization of the molecules in such a way as to bring the cross linkable double bonds closer to each other. The present invention also involves a UV curable formulation of the above mentioned resins along with 2-10 parts by weight of a photopolymerization initiator. The resin, either in a formulation or alone turns into a cross linked film upon photopolymerization in presence of photoinitiator under a UV curable radiation source like a mercury vapor pressure lamp.
