Silicon tetrachloride: A potential wood preservative
1980 - IRG/WP 3133
In its present form, this paper is a preliminary draft of a paper that will eventually be submitted for publication in the Forest Products Journal. We are continuing the work on the effects of silicon tetrachloride on wood and expect to have additional data for the meeting in May 1980. Specifically we are measuring the penetration rate and depth of SiCl4, and we are chemically analyzing the treate...

Preliminary results of the treatment of wood with chlorosilanes
1981 - IRG/WP 3172
It is clear from the initial data reported here that the treatment of pine sapwood with chlorosilanes under the reaction conditions employed did not significantly reduce the decay by both white rot and brown rot fungi. Only the dichlorosilane compounds showed to possess some protective action against fungal attack. Before drawing conclusions on the application of organosilicon compounds as potenti...

Evaluation of outdoor weathering performance of modified wood
2004 - IRG/WP 04-20296
Interlace treated, oil treated, silicon treated as well as untreated Scots pine samples have been exposed outdoors. For evaluating the samples on their long term performance an internal standard had been developed. Parameters to be determined were the uptake of liquid water (submersion test), weight variation during exposure, crack performance, surface roughness and colour change. This paper disc...

Decay and termite resistance of wood treated with boron-containing quaternary ammonia compound, didecyl dimethyl ammonium tetrafluoroborate (DBF) incorporated with acryl-silicon type resin
2004 - IRG/WP 04-30334
This study evaluates the decay and termite resistance of surface-treated wood with didecyl dimethyl ammonium tetrafluoroborate (DBF) incorporated with acryl-silicon type resin emulsion. DBF is a quaternary ammonia compound and contains boric tetrafluoride (BF4-) as a counter ion in its chemical structure. In the study, DBF was incorporated with an acryl-silicon type resin to increase water-resista...

Restrictions on the use of chlorosilanes as potential wood preservatives
1985 - IRG/WP 3345
The biological protection of wood by chemical modification with different types of chlorosilanes has been investigated. The impregnation of wood has been carried out by means of liquid phase and vapor phase treatments using pure silane and silane-solvent systems. The biological efficacy against wood rotting fungi, molds and staining fungi was determined in a number of screening trials, subsequentl...

Laboratory and above ground exposure efficacy of silicon-boron treatments
2009 - IRG/WP 09-30510
The study deals with silicon compounds, namely tetraethoxysilane (TEOS), phenyltriethoxysilane (PhTES) and methyltriethoxysilane (MTES) at concentrations of 23, 16 and 10% in combination with 1.2-1.5% boric acid. The aim with the study was to combine the chemical approach with the necessary biological tests of the impregnated wood. The tested silicon-boron combinations ensured mass loss less than ...

Silicon compounds as additives improving alkyd-based wood coatings performance
2010 - IRG/WP 10-40531
The reactivity of cellulose with solvent-born alkyd-based wood coatings supplemented with organosilanes was analyzed. Structural analysis of cellulose subjected to the reaction with organosilanes and following extraction with water was performed using Fourier-transform infrared spectroscopy (FTIR). The analyzed IR spectra comprise bands 1250 cm-1 typical for the SiC group and 800 cm-1 typical for ...
