    Abstract: An improved resin for use in making honeycomb sandwich panels. The improvement involves modifying a phenolic resin so that the amount of smoke and heat generated during combustion is reduced. The reduction in smoke and heat generation is achieved by reducing the amount of phenol used to form the phenolic resin. The phenol is replaced by low-smoke producing sulfone compounds such as 4,4′-bisphenol-S, 3,3′-bisphenol-S, biphenol and bisphenol ethers which reduce the number of smoke producing methylene or methylene ether linkages present in the cured phenolic resin. The low-smoke producing resin may be used as a dip resin for coating the honeycomb or as the matrix resin for the core and face sheets of the sandwich panel.

  • Patent number: 6586557
    Abstract: Provided is an improved binder for use of fiberglass insulations and glass mats. The fiberglass binder is a triazone material prepared from urea, formaldehyde and a primary amine or a mixture of a priamary amine and ammonia. The binder of the present invention provides an increase in nitrogen content, while lowering the costs of manufacturer and improving performance. The binders of the present invention also exhibit lowered emissions and excellent high temperature properties.

  • Patent number: 6482874
    Abstract: The present invention provides a method of accelerating hardening of thermosetting resin and a device therefor such that hardening time is rendered far shorter than in the case of the prior art. By way of a pertinent means, when unhardened thermosetting resin is to be disposed in an atmosphere having a specified temperature for the purpose of hardening, a ceramic plasma spraying plane is formed in at least one portion, or preferably in as large an area as possible, in the above-mentioned atmosphere whose temperature is maintained at a specified level and in which the above-mentioned resin is disposed, thereby causing convective heat existing in the hot air to be thermally converted into far infrared radiant heat radiation from the ceramic plasma spraying plane mentioned above.

  • Publication number: 20020042495
    Abstract: The present invention is drawn to polyamide ligand-containing polymeric resins and methods of using the same for removing, separating, and/or concentrating certain desired metal ions from solutions, even when the desired ions are in the presence of other metal ions and/or hydrogen ions at much higher concentrations. The unique composition of matter of this invention is a polyamide ligand-containing polymeric resin which is a reaction product of a hydroxymethylated polyamide ligand and a polymerization and/or crosslinking agent. Specifically, the polymeric resins of the present invention are comprised of from 10 to 50,000 polyamide ligand units wherein each polyamide ligand unit contains at least three amide groups (preferably from three to eight amide groups) and two amine groups separated by at least two carbons. Each amide group, after polymerization, may remain hydroxymethylated or be crosslinked to other polyamide ligand units through a crosslinking agent.
