Vinyl Benzoate Photostabilizes Wood Whereas Vinyl Cinnamate and Vinyl 4-T-butylbenzoate are Less Effective
2009 - IRG/WP 09-40452
Thin wood veneers were esterified to different weight gains with three different aromatic vinyl esters, vinyl benzoate, vinyl cinnamate and vinyl 4-T-butylbenzoate and the photostability of the modified wood was examined. There was a linear relationship between the level of esterification of wood with vinyl benzoate and the photostability of the modified veneers exposed to natural weathering. Viny...

Fire resistance of Alder wood treated with some chemicals.
Part II. Effect of Other Chemicals on the Combustion Properties
2002 - IRG/WP 02-40235
Samples from alder wood (Alnus glutinosa (L.) Gaertn. subsp. barbata (C.A.Mey) Yalt.) were impregnated according to ASTM D 1413-88 with boron compounds (boric acid, borax,
sodium perborate), vinyl monomers (styrene, methyl methacrylate), Tanalith-CBC, Phosphoric acid, Vacsol, Immersol, Polyethylene glycole (PEG-400) and their mixed solutions of chemicals in order to determine their combustion pro...

Some tests on ES - AS 11, a novel anti-sapstain formulation, and its properties
1987 - IRG/WP 3399
The results of some tests with the formulation ES - AS 11 are given. The formulation is an attempt to improve the performance of an anti-sapstain chemical by: 1) increasing its penetrability 2) uniquely combining its active ingredients. Very short times of treatment (dipping not longer than 5 seconds), low concentrations of active ingredients, and lower toxicological and environmental risks may be...

Giftwirkung einiger organischer Zinn-Verbindungen auf Eilarven von Hylotrupes bajulus (L.). [Toxic efficacy of some organic tin compounds against egg larvae of Hylotrupes bajulus (L.)]
1978 - IRG/WP 2120
The toxic values of 12 organic tin compounds towards newly hatched larvae of Hylotrupes bajulus were determined after 4- and 12-week test periods in comparison with bis-tri-n-butyltin oxide (TBTO). Tri-n-butyltin benzoate as well as the 2-, 3- and 4-methyl benzoate of tributyltin oxide were equally effective as TBTO and the latter two were somewhat more effective after a 12-week test period. Almos...

Physical and mechanical properties of wood-polymer composites prepared from alder wood (Alnus glutinosa (l.) gaertn. subsp. barbata (c.a.mey.) yalt)
2001 - IRG/WP 01-40201
In this study, the physical mechanical properties of wood-polymer composites prepared from alder (Alnus glutinosa (L.) Gaertn. subsp. barbata (C.A.Mey.) Yalt) wood were investigated. Three different monomers styrene, methyl methacrylate and styrene/methyl methacrylate (70/30) mixtures and two loading levels were used in preparation of wood-polymer composites. Of physical properties, the oven-dry s...

Determination methods of phytotoxic effect of wood preservatives
1990 - IRG/WP 2349
The phytotoxic effect of wood preservatives so widely used plays a considerable role in the protection of natural environment. A review was made of the existing methods with which to assess the phytotoxicity of the above chemicals and some suggestions were given concerning the methods most appropriate for their unification. Two areas of research are proposed: 1) estimating the direct effect on ind...

A new process for in situ polymerization of vinyl monomers in wood to delay boron leaching
1998 - IRG/WP 98-40110
Efforts were accelerated on effective use of boron compounds in wood preservation owing to their environmentally safe characteristics and relatively low costs in addition to their well-known high bioactivity and fire resistant properties. Although having these unique favorable properties, they are readily leachable from treated wood at humid conditions. Therefore, they had limited market for exter...

Effects of intumescent formulation of vinyl acetate-based coating on flame-retardancy of thin painted red lauan (Parashorea spp.) plywood
2011 - IRG/WP 10-40537
Using intumescent coatings on wood-based materials is an effective method for fire safety. The intumescent coatings consist of four major components: (1) binder resin (BR), (2) carbonizing substance (CS), (3) foam producing substance (FPS) and (4) dehydrating agent (DA). Previous studies have demonstrated that the formulation of the four components strongly influences the performance of coatings. ...
