Special Issue Information

Dear Colleagues,

I would like to invite you to submit your work to this Special Issue entitled “New Challenges in Wood Adhesives and Coatings (Second Volume)”. Adhesives and coatings applied to wood products have several similarities, including the nature of their interactions with the support; the chemical moieties of the constituting polymers; new constraints requiring a reduction in human and environmental toxicity (e.g., lower VOC emissions, formaldehyde-free, and low-odor systems); the growing interest in the application of sustainable raw materials to replace petrochemical products; the use of bio-based resources (including vegetable oils and new renewable monomers) to re-think the use of synthetic chemicals; the impact of advanced and newly developed materials such as nanoparticles and nanosystems; applications employing substrates alternative to wood (including vinyl, MDF, plastic composites, metals, etc., mostly important in the furniture and building sectors) or modified wood (e.g., heat-treated, acetylated, furfurylated, etc.); and increasing demand for enhanced properties and performance, which also implies the development of novel testing techniques and characterization methodologies. All of these topics are of interest for this Special Issue.

Of course, both wood adhesives and coatings also have unique properties, and topics related to these are also welcome in the Special Issue. They include, for instance, the use of lignin or carbohydrates in formulations, research addressing alternative co-reactants in vegetable proteins, the gluing of hardwoods for structural applications, the development of exterior-grade adhesives and glued wood products (e.g., CLT) in the case of wood adhesives, the development of new transparent stains or varnishes in outdoor applications, the progress of radiation-curable (e.g., UV, EB, visible light) resins for clear matte coatings and systems, and the innovative drying of shellacs and lacquers in the case of wood coatings.

Thus, this Special Issue will highlight new advancements in wood adhesives and coatings, and analyze processes and products that are scientifically valuable or aid in the industrial development of novel processes. Authors are encouraged to submit their latest research on the suggested topics in the form of experimental and theoretical original research or review articles.

Biofinish is an innovative wood protection system inspired by biological processes. It enhances the hydrophobicity of wood through oil treatment, resulting in improved dimensional stability. Living cells of the fungus Aureobasidium pullulans effectively protect wood from deterioration caused by other decaying fungi. The melanin pigment produced by the fungus provides an appealing dark surface and additionally protects the wood substrate against UV radiation. The significant advantage of Biofinish is its remarkable self-healing ability, which distinguishes it from conventional wood protection methods. This research aimed to explore fungal species colonising surfaces exposed to natural weathering and assess the survival of A. pullulans on wood surfaces coated with Biofinish during its in-service period. This study was performed on a facade composed of European larch wood (Larix decidua) treated with linseed oil and coated with Biofinish at the InnoRenew CoE building in Izola, Slovenia, following a 9-month exposure period. The majority of the detected species belonged to the genera Aureobasidium. The results indicated the survival and effective antagonistic action of A. pullulans, the living and active ingredient of the coating, against other wood-decaying fungi. Full article

This work presents the effect of steaming beech, birch and maple woods on the resulting quality of the milled wood surface. The steaming process of the studied woods results in a targeted change in the color of the wood, which changes from the original light white-gray color to fine reddish-brown to dark brown color shades that are more or less saturated depending on the temperature of the saturated water steam. The color changes achieved during the modification process were identified using coordinates in the CIE L*a*b* color space. The achieved color changes were described through the total color difference of ΔE* and defined through classification grades using a color scale. The technological process of wood steaming with saturated water steam for the purpose of a targeted change in the color of the wood and experimental measurements of the roughness of the milled wood surface proved that the wood steaming process has a positive effect on the roughness of the wood surface of the investigated trees, depending on the steaming temperature. The reduction of roughness in the process of the modification of beech wood compared with native wood was at the temperature of the saturated water steam as follows: tI = 105 ± 2.5 °C by Ra = 12.3%, at tII = 125 ± 2.5 °C by Ra = 15.4%, at tIII = 135 ± 2.5 °C by Ra = 16.9%. By modifying birch wood at tIII = 135 ± 2.5 °C, the roughness decreased by Ra = 13.4%; the surface roughness decreased by Ra = 15.8% compared with native wood by modifying maple wood. The roughness of the milled surface of modified wood in individual treatment modes decreased compared with native wood, which means that the milled surface of modified wood is of a better quality, which is positive for its practical use.
