Influence of different resin treatments on the dimension stability of wood
M Sailer, A O Rapp
The dimension stability of wood is considered to be an important contribution to its durability and its performance in practice. A number of different treatments have been developed to improve the dimension stability of wood. One applied method is the treatment of wood with monomers or resins. The application of appropriate impregnation conditions seemed to be essential to enhance the efficiency of the treatment with water based resins. Therefore, wood samples of the three wood species Pinus sylvestris L., Pinus radiata D. Don. and Fagus sylvatica L. were impregnated with four different resin systems to evaluate the influence of different parameters on the anti-swelling efficiency (ASE). Variation in diffusion time, initial moisture content and resin concentration revealed considerable differences in retention of the resins and the ASE.
