  • Hybrid phenol-formaldehyde and polymeric isocyanate based adhesive and methods of synthesis and use
    Publication number: 20030092855
    Abstract: Hybrid resins formed of an acylated phenol-formaldehyde (PF) resin and a polymeric phenyl isocyanate (pMDI) resin have extended shelf stability, yet cure at a rate faster than any of its components when used in conventional flakeboard, strandboard or other board making processes.
    Type: Application
    Filed: November 8, 2002
    Publication date: May 15, 2003
    Inventors: Todd R. Miller, Lewis D. Creel, William D. Detlefsen

  • Method for bonding lignocellulosic material with phenol-formaldehyde resin and carbon dioxide
    Patent number: 5902442
    Abstract: Subjecting lignocellulosic components coated with an aqueous alkaline phenolic resole resin solution to carbon dioxide inhibits overpenetration of resin and improves bond strength when the coated components are heated to cure the resin by application of steam and pressure in the preparation of structural panels. Also, contact with carbon dioxide of high moisture resin coated lignocellulosic components accelerates the speed of cure and improves bond strength of panels cured under heat and pressure.

  • Foamability of phenolic resins
    Patent number: 5057591
    Abstract: The invention is a solution of highly advanced phenolic resin with improved inherent foamability that is made from the reaction of phenol, aldehyde, water and alkali the improved foamability being brought about by the incorporation of up to 1.0% by weight, anhydrous basis, lime (calcium hydroxide) into the early stages of the reaction mix. In another embodiment, the invention is a plywood glue composition comprising a solution of lime-containing highly advanced phenolic resin, dried animal blood and preferably an aldehyde glue viscosity-lowering agent.
