  • Alkylresorcinol modified phenol-aldehyde resol resin and binder system, and method of making same
    Patent number: 5847058
    Abstract: A process for the production of a storage-stable, modified phenol-aldehyde resol resin includes the use of an alkylresorcinol modifier and preferably a readily-available mixture of alkylresorcinols. A binder system includes the modified phenol-aldehyde resin combined with a curing agent that includes an additional source of an aldehyde, e.g., a phenol-formaldehyde resin. The resin and binder system are useful in the production of a wood composite (such as plywood, oriented strandboard, or fiberboard).
    Type: Grant
    Filed: April 5, 1996
    Date of Patent: December 8, 1998
    Assignee: Masonite Corporation
    Inventor: Zygmunt Teodorczyk
  • Binder resin, binder system, cellulosic composite articles, and method of making the same
    Patent number: 5756599
    Abstract: A process for producing a phenol-aldehyde (e.g., cresol-aldehyde) resin that is modified with a dihydroxybenzene compound. The resin may form a binder system when combined with a curing agent which includes an additional source of an aldehyde. The resin and adhesive are useful in the production of wood composite articles by a steam injection process.
    Type: Grant
    Filed: July 7, 1997
    Date of Patent: May 26, 1998
    Assignee: Masonite Corporation
    Inventor: Zygmunt Teodorczyk
  • Method of preparing binder system and product thereof
    Patent number: 5646219
    Abstract: A process for the production of a modified phenol-aldehyde resin which may form a binder system when combined with a curing agent which includes an additional source of an aldehyde, e.g., a phenol-formaldehyde resin. The inventive phenol-aldehyde resin may be modified with compounds from one of the following classes: (1) dihydroxybenzenes, (2) aminophenols, and (3) phenylenediamines. The resin and adhesive are useful in the production of a wood composite (such as plywood, oriented strandboard, or fiberboard).

  • Modified phenol-aldehyde resin and binder system
    Patent number: 5637658
    Abstract: A process for the production of a modified phenol-aldehyde resin which may form a binder system when combined with a curing agent which includes an additional source of an aldehyde, e.g., a phenol-formaldehyde resin. The inventive phenol-aldehyde resin may be modified with compounds from one of the following classes: (1) dihydroxybenzenes, (2) arninophenols, and (3) phenylenediamines. The resin and adhesive are useful in the production of a wood composite (such as plywood, oriented strandboard, or fiberboard).

  • Method of manufacturing cellulosic composite and product thereof
    Patent number: 5629083
    Abstract: A process for the production of modified phenol-aldehyde resins includes the use of a modifier selected from melamine, urea, and other suitable nonvolatile organic compounds. The phenolic component of the resins preferably includes a difunctional phenolic compound. The inventive resins resist precuring and are particularly useful in blowline blending procedures.

  • Precure resistant thermoset resin for molded wood composites
    Patent number: 5367040
    Abstract: A process for the production of modified phenol-formaldehyde resins includes the use of a difunctional phenolic compound as the phenolic component of the resins. The inventive resins resist pre-curing and are useful in the production of molded wood composites produced, for example, by wet-dry forming processes.
