  • Patent number: 5731081
    Abstract: Glass fiber evaporative cooler media are provided having melamine-formadehyde resin binders coated on the glass fiber. These melamine-formaldehyde coated glass fibers provide evaporative cooler pads with increased capallarity or surface sheeting characteristics while simulataneously demonstrating increased water resistance or hydrophobicity. The melamine-formaldehyde resins of the present invention furthermore provide coatings having greater resistance to thermomigration of binder during drawing. The melamine-formaldehyde binders of the present invention are of three types based upon the resins used: 1) melamine-formaldehyde/urea-formaldehyde; 2) melamine-formaldehyde only; and 3) melamine-formaldehyde/polyurethane.

  • Patent number: 5622776
    Abstract: Hydrophilic glass fibers are formed by coating glass fibers with a blend of an amine-aldehyde with an acrylic. Evaporative cooler pads are produced by coating glass fibers with a blend of an acrylic and an amine-aldehyde during hot melt spinning of the glass fibers into a web, followed by drawing the web to expand the web or mat into a porous pad, and curing the pad to produce a dimensionally stable, hydrophilic, porous, glass fiber pad. Preferably, the glass fibers are coated with a binding/hydrophilic coating formed of a blend of a urea-formaldehyde with an acrylic. A method for cooling air using the hydrophilic, porous, glass fiber pads, and an improved evaporative cooler utilizing hydrophilic, porous, glass fiber pads is disclosed.
