Abstract (en)
[origin: US2010003411A1] A method of treating wooden parts is described in which a) the wooden parts are impregnated with an aqueous cyanamide solution and subsequently b) the impregnated wooden parts, where appropriate after drying, are subjected to a heat treatment of 130 to 250° C. Here it has surprisingly emerged that impregnation with cyanamide even in small amounts has a significantly positive influence on the performance properties of the treated wooden parts, such as high hardness, low water absorption and very good weathering stability, for example. Moreover, only small amounts of a toxicologically and environmentally unobjectionable impregnating agent are needed in order to obtain these advantageous properties.
