ABSTRACT:
Wood and other cellulose-based products are preserved with a water-based treating solution containing a phenolic resin prepolymer such as phenol formaldehyde resin prepolymer, a resorcinol formaldehyde resin prepolymer and water. The treatment is carried out by exposing the wood or other cellulose-based product, while submerged in the treating solution, to one or more cycles of reduced pressure (i.e. vacuum) and elevated pressure.
