Abstract:
A hydroxymethylated resorcinol coupling agent is provided, including a hydroxymethylated resorcinol as an active ingredient, which enables commercial thermosetting adhesives such as bisphenol-A epoxy, phenol-resorcinol-formaldehyde, emulsion-polymer isocyanate, phenol-formaldehyde, resorcinol-formaldehyde and other resins of similar chemical nature to develop strong and durable bonds to a variety of untreated and preservatively treated woods. The resulting bonds to wood withstand delaminating stresses that occur with weather and water in exterior environments.
