Melamine-aldehyde Condensate Patents (Class 442/162)
  • Publication number: 20130337712
    Abstract: Polyester materials, methods for making polyesters materials, and uses of the polyester materials in binder materials and articles of manufacture are disclosed. In one embodiment, a process is provided for preparing a polyester solution, including mixing monomers of at least one organic acid containing at least three carboxylic groups and at least one multi-hydroxyl alcohol containing at least three hydroxyl groups to form a reaction mixture, heating the reaction mixture to a first temperature, polymerizing the monomers at the first temperature until reaching an acid value from about 200 to about 400 mg KOH/g, adjusting the temperature to a second temperature less than the first temperature, and forming the polyester solution. The polyester materials may be mixed with cross-linking materials to form binder materials. The binder material may then be used to form articles of manufacture.

  • Patent number: 7250381
    Abstract: Fibrous nonwoven mats comprising polyetherimid fibers and a binder comprising a resin and an adhesion promoter, and method of making the mat are disclosed. These mats have several uses and are particularly suited as facer mats for fiber reinforced thermoplastic thermoformable materials. When used as a facer, the mat bonds to the thermoformable material and provides a resin rich outer layer and facilitates bonding to a decorative cover.

  • Patent number: 6083854
    Abstract: The present invention relates in general to a variety of emulsion compositions, and more particularly, to emulsion compositions and methods for preparing these emulsion compositions which employ novel polymeric emulsifaction techniques. The emulsion compositions of this invention although applicable to a variety of applications provide particularly stable low viscosity polymeric emulsions useful for example in connection with wet wipes for the treatment of adult or baby dermatitis, make-up removal and other skin care applications. The stabilizing composition used in the emulsions according to the present invention comprise phenoxyethanol.
