Abstract :This study was performed to determine the effects of impregnation with boron compounds and water repellents on the dimensional stability of wood. For this purpose,   the test specimens prepared from scotch pine (Pinus sylvestris L.) wood   which met the requirements of TS 345 and TS 1476 standards procedures were single, double or multi treated according to   ASTM D 1413-76 standard procedure with some boron compounds such as boric acid (Ba) and borax (Bx), some water repellent materials (WRM) such as styrene, methyl methacryrilate, izocyonate, polyethyleneglychol-400 (PEG-400), and some   commercial impregnation materials such as Tanalith-CBC (T-CBC), ammonium sulfate (AS), diamonium phosphate (DAP), and vacsol. As a result, secondary treatment with WRM decreases amount of leached material. Water absorption ratio of wood was lowest in the treatment only with WRM, boron compounds and   in secondary treatment of PEG-400 with WRM. Order of convenience for dimensional stability was like WRM>(Ba+Bx)+WRM>PEG-400+WRM>commercial impregnation materials. Order of convenience for volumetric shrinkage efficiency was like (Ba+Bx)+WRM>PEG-400+WRM>AS, DAP, T-CBC. WRM was found more successful in leaching prevention when used as a secondary treatment after PEG-400. So, the wood which will be used in open air and high relative humidity conditions, secondary impregnation with WRM is recommended.
