Abstract: The present invention relates to a process for treating wood and other cellulosic materials to render the resistance to wood attacking organisms, such as termite, fungi and insects. More particularly, the present invention relates to a process for treating wood with borate preservative formulation which contains at least one boron-containing component and at least one resinous component capable of retaining impregnated borate inside the treated wood even upon contact with water. The resinous component may be rosin, rosin derivative, tall oil-based compound, or mixtures thereof.

Abstract: This invention relates to a method for making hardened wood by treating wood with acrylic/rosin/fatty acid-based formulations. Furthermore, the invention relates to a method for treating non-heartwood pine with acrylic/rosin/fatty acid-based formulations in order to give the treated non-heartwood pine the aesthetic appearance similar to that exhibited by yellow pine heartwood and the hardness similar that exhibited by oak.

Abstract: This invention relates to a method for treating wood and the treated wood. More particularly, the invention relates to a wood treatment method for making wood resistant to insect and soil microbe damage by impregnating the wood with a mixture of at least one borate and at least one rosin and/or rosin derivative.

Abstract: This invention relates to the production of artificial pine heartwood. More particularly, the invention relates to a method for treating sapwood from trees of the family Pinaceae with rosin and/or a rosin derivative in order to give the treated sapwood physical and esthetic properties similar to that exhibited by yellow pine heartwood.
