In this regard, the fashion trend in furniture used for home décor, hotel and workplace area is rapidly growing. Wood is the most common and popular material used in decorative furniture. However, with the indiscriminate destruction of trees and depleting forests, availability of a specific quality of wood required for durable furniture making is declining and becoming quite expensive. Therefore, instead of using sol id wood from the stem or bark of a tree, only a thin layer of wood is cut and then pasted on the exterior part of other suitable material to impart a natural and fashionably vintage look to the furniture.

Colour stability of wood coatings pigmented with natural indigo from Isatis tinctoria after accelerated weathering / Juha Jordan in COLORATION TECHNOLOGY, Vol. 138, N° 2 (04/2022)

The two coatings, natural indigo-pigmented boat varnish and outdoor paint, were exposed to cycles of ultraviolet light, water condensation and water spray for 40 days in a QUV test chamber. Synthetic indigo and commercial ultramarine pigment were employed as reference materials. The effects of artificial weathering on the coatings were evaluated with CIELab parameters, as well as visual inspection. Coating and pigment stability during artificial weathering were studied with reflectance spectrometry, hyperspectral imaging technology and Fourier Transform–infrared spectroscopy. According to the results, coatings with indigo proved to be more resistant to visual and spectral changes than unpigmented or commercially pigmented coatings.

Depth profile of UV-induced wood surface degradation / V. Jirous-Rajkovic in SURFACE COATINGS INTERNATIONAL. PART B : COATINGS TRANSACTIONS, Vol. 87, B4 (12/2004)  

[article]  inSURFACE COATINGS INTERNATIONAL. PART B : COATINGS TRANSACTIONS > Vol. 87, B4 (12/2004) . - p. 241-247 Titre : Depth profile of UV-induced wood surface degradation Type de document : texte imprimé Auteurs : V. Jirous-Rajkovic, Auteur ; H. Turkulin, Auteur ; E. R. Miller, Auteur Année de publication : 2004 Article en page(s) : p. 241-247 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Bois -- Détérioration Bois -- Effets du rayonnement ultraviolet Bois -- Teinture Essais accélérés (technologie) Essais dynamiques Lasures Photostabilisants Résistance à la traction Sapins Traitement chimique Index. décimale : 667.9 Revêtements et enduits Résumé : The depth profile of weathering effects on wood was studied after the laboratory ultraviolet exposure of fir-wood. The ‘thin strip’ method (ie the measurement of changes in tensile properties of microtomed wood sections) was modified in terms of exposure of batches of strips packed in bundles and exposed in a QUV apparatus. The bundles of strips were exposed untreated, covered with surface strips that had been impregnated with chromium (VI) trioxide or Fe(III) nitrate, or protected with free films of clear stain with photostabilisers and without photostabilisers. It has been shown that ultraviolet (UV) light penetrates the fir-wood surface to a depth greater than 70µm, resulting in changes in the tensile strength of the fir-wood strips to a depth of 70 to 140µm. Strength changes in lower levels (down to 280µm from the surface) could not be clearly attributed to a predominant effect of UV light, and were probably controlled by hydrolytic processes. 100 hours of exposure enabled the effectiveness of several treatments to be established. The clear stain, enriched with a UV absorber (Tinuvin 1130. Ciba) and a hindered amine light stabiliser (HALS compound type) (Tinuvin 292, Ciba), was shown to offer the best protection of the treatments studied. Impregnation with aqueous solutions of chromium (VI) trioxide and Fe(III) nitrate proved ineffective in photostabilising the wood surface.
