During the application of low molecular weight PF resin composed with fire retardant FRDL-112 or H3BO3 to Poplar (Populus ussuriensis) wood, the resin with FRDL-112 added was found to impregnate the wood more easily than that with H3BO3 added. The latter affected the anti-swelling or shrinkage and moisture excluding properties of PF modified wood more than FRDL-112 did.
