ABSTRACT:
A process for the accelerated fixing of fixable chromate-containing wood preservatives in which wood freshly impregnated by any of the full-cell, modified full-cell, empty-cell, or modified empty-cell treating processes are subjected to fixing by contacting the wood with hot liquid medium, such as water, which liquid is either initially hot or is rapidly heated to sufficient temperature so that the entire bundle of wood is brought to a temperature sufficient for complete fixation to occur within an economic period of time either within or after removal from the liquid medium.
