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,...

Study on the Effect of Combined Nanosilver-Hygrothermal Treatment on Wood Properties
2012 - IRG/WP 12-40581
In this study, the impregnation process with nanosilver solution, before hygrothermal treatment was carried out to investigate its effect on some physical and mechanical properties of Iranian beech (Fagus orientalis Lipsky) and imported Russian spruce (Picea abies). Wood specimens were impregnated with nanosilver solution (400ppm) in an impregnation tank under pressure of 0.25 Mpa, for 20 minutes....

Hydrogels: a solution to reduce boron leachability without reduction of its biodisponibility to wood decaying fungi?
2012 - IRG/WP 12-30602
Products used today for wood protection must fulfill to more and more environmental constraints, such as being of low toxicity in answer to the Biocidal Product Directory, but also to involve waterborne treatments to limit rejection of volatile organic compounds in the atmosphere. Boron preservatives have been described as valuable alternatives for wood protection for non-ground contact applicatio...

Developing Analytical Methods for Determination of Quaternary Ammonium Compounds (DDAC) using HPLC and HPLC-MS (Application to treating solution and preservatives treated wood)
2013 - IRG/WP 13-20516
Korea preservative treating industry has mainly used alkaline copper quaternary (ACQ) expected over 80% of market share in Korea. ACQ employs dodecyl dimethyl ammonium chloride (DDAC) and benzyl dimethyl dodecyl ammonium chloride (DBAC) for active ingredient along with copper. The strongly increasing domestic applications for wood preservatives require developing accurate and reproducible analytic...

Overview of the treated wood quality control program in the United States with the recent challenges and advances
2017 - IRG/WP 17-20616
In the past two decades, there have been significant and rapid changes in wood protection technologies for residential applications which have moved away from long established heavy duty metal oxide based products such as chromated copper arsenate (CCA). The successor generation of wood protection systems usually contain copper as the primary biocide, in combination with carbon-based co-biocides s...

Effect of pretreatment of wood surfaces with a copper monoethanolamine solution on the natural weathering performance of semitransparent stains
2019 - IRG/WP 19-40881
Semitransparent stains for wood products are favored for outdoor applications in Japan because these finishes do not hide the wood grain. However, the photoprotective effects of wood surfaces are low, therefor there is a need to improve the weathering performance. We examined the natural weathering performance of semitransparent stains on wood pretreated with a copper monoethanolamine solution (Cu...
