  • Melamine in urea-extended phenol/formaldehyde fiberglass binders
    Patent number: 6441122
    Abstract: Urea-extended phenol/formaldehyde alkaline resole binders suitable for fiberglass and having a high binding efficiency are disclosed. These binders are prepared by adding a minor quantity of melamine in an amount such that the binder solution contains no solid melamine particulates at room temperature. The resulting binders, when applied to fiberglass and cured, have a binding efficiency close to 100%, and further increase the recovery and physical properties of the binder-containing fiberglass product.
