Alkylresorcinol modified phenol-aldehyde resol resin and binder system, and method of making same

摘要

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).
