Fixation of CCA in Pinus sylvestris after kiln-drying
1990 - IRG/WP 3594
Tanalith C Paste is 98% fixed and Tanalith Oxide C is 99% fixed irrespective of whether treated Pinus sylvestris is kiln or air dried. A schedule suitable for kiln drying of CCA treated Pinus sylvestris is described....

Diffusion of a copper naphthenate/boron paste through Douglas fir heartwood
1991 - IRG/WP 3671
Groundline wraps are an important portion of the remedial treatment strategies for protecting utility poles in North America from surface decay. The compositions of these wraps have recently shifted away from pentachlorophenol and creosote to formulations containing copper naphthenate and boron. These formulations have not yet been extensively tested, although the chemicals have been used for many...

Remedial treatment of creosoted railway sleepers of redwood by selective application of boric acid
1980 - IRG/WP 3134
An ideal preservative for remedial treatment must primarily be characterized by two requirements. First, it must have an ability to diffuse and distribut evenly into the wood and secondly, it must be fixed properly so that it does not leach out too fast. However, these two characteristics conflict with each other, and the choice of preservative must of necessity be a compromise. Wood preservatives...

BG- an easiest preservative paste and its effective diffusibility in timbers for indoors and outdoors uses
2001 - IRG/WP 01-30253
After application of a newly formulated paste "BG-1" on all surfaces of air-dried lumbers, the boron have been found diffused completely in permeable and impermeable hardwoods at the rate of 12 mm radial thickness per week. The new paste may be a solution to protect lumbers being used or to be used under cover where timber is susceptible to termite and borer attack. The new cost effective paste wa...

Remedial ground-line treatment of CCA poles in service. A progress report after 28 months' testing
1988 - IRG/WP 3481
Remedial treatments of CCA-treated poles in service with incipient soft rot were carried out with boron rods, boron/glycol solution, boric acid paste, copper/creosote paste and a commercial product (DFCK paste) respectively. The micro-flora before remedial treatment and 6 months after as well as the spread of chemicals in the poles were reported in Document No: IRG/WP/3388. In this progress report...

Environmental safeness of 60% and 72% concentrated CCA-C solution and paste for wood treatment
2012 - IRG/WP 12-50284
In this study 30-years practical and observational experience of the present author about using of 72% concentrated CCA-C paste for preparing treating solutions and for treating wooden poles, anchor logs and cross arms has revealed that the 60% concentrated CCA-C solution is superior to the 72% concentrated CCA-C paste regarding solubility, homogeneity, cleanliness, treatability, sludge formation,...

Brief introduction to a research project on preparations of various paste formulations from boron, fluoride and copper for supplemental treatments
2022 - IRG/WP 22-30759
Wood preservatives to be used for supplemental purposes are present in various forms such as powders, liquids, rods, pastes, or gels. Boron compounds have been receiving a lot of attention in supplemental treatments since they have good mobility in wood. Application of boron compounds via internal treatments is vital to stop decay to be occurred inside the wood since large wood elements are too th...
