  1. The central role of wood biology in understanding the durability of wood-coating interactions

    To design effectively for durability, one must actively and honestly assess the material properties and limitations of each of the components in the design system; wood or wood composite, and the coating. Inasmuch as wood coatings are manufactured to specified tolerances from known materials, we have control of that component of the system. Compared to manmade...

  2. Weathering characteristics and moisture uptake properties of wood coated with water-borne sol-gel thin films

    In this study, wood specimens were coated with water-borne silsesquioxane oligomers by an in situ sol-gel deposition process. The effect of these water-borne sol-gel thin films on weathering characteristics and moisture-uptake properties of the wood specimens were investigated. The weathering characteristics were investigated by exposure of the specimens to artificial...

  3. The Potential for Check Reduction Using Surface Coatings

    Surface checking in red oak causes considerable loss in lumber that is used in the furniture and flooring industry. In this series of experiments, a surface coating was applied to unseasoned, presurfaced red oak lumber in order to restrict the moisture loss from the surface to test the hypothesis that a reduction in the rate of surface moisture loss would reduce...

  5. Weathering Performance of Wood Coated with a Combination of Alkoxysilanes and Rutile TiO2 Heirarchical Nanostructures

    The weathering performance of wood coated with a combination of rutile TiO2 hierarchicalnanostructures and a sol-gel deposit of alkoxysilanes was determined by exposing three sets of specimens to UV light and water spray.

    Accelerated weathering of wood surfaces coated with hexadecyltrimethoxysilane (HDTMOS) in the presence of methyltrimethoxysilane (MTMOS) by the sol-gel process was investigated. The sol-gel process allowed the deposition of a covalently bound thin layer of polysiloxane networks on the wood surface that was resistant to water sorption and water leaching. The rate of...

  7. High-performance envelopes for wood

    Wood can be coated with a clear finish, stained or painted to provide protection from water and ultra violet energy. In this case the coating and wood are two different phases that coexist. Another approach is to provide protection by “coating” in the surface not on the surface. Such an approach is referred to as an envelop rather than a coating. This can be done in...

  8. Polystyrene/wood composites and hydrophobic wood coatings from water-based hydrophilic-hydrophobic block copolymers

    The combination of synthetic thermoplastic polymers and wood is normally problematic because wood surfaces are hydrophilic while typical thermoplastic polymers are hydrophobic. A possible solution is to use block copolymer coupling agents. In this work we show the use of a potentially useful synthetic method of producing hydrophilic-hydrophobic block copolymers as...

  9. Can biochar be used as a seed coating to improve native plant germination and growth in arid conditions?

    Direct seeding is a common large-scale restoration practice for revegetating arid and semi-arid lands, but success can be limited by moisture and temperature. Seed coating technologies that use biochar may have the potential to overcome moisture and temperature limitations on native plant germination and growth. Biochar is a popular agronomic tool for improving soil...

  16. Do petroleum-based protective coatings add fuel value to slash

    Asphalts and wax emulsions have been recommended as protective coatings to help obtain clean, safe burns in slash disposal work. Fuel value determinations in the laboratory indicate that such coatings add little to the fuel value of slash.

  17. Water-repellent preservative treatment of brick molding prior to factory priming improves paint service life

    One end of each piece of brick molding (about 35 mm long) was dipped in a water-repellent preservative (WRP). Following the WRP treatment, the sections were divided into two groups and painted with one of two different primers formulated to be typical of factory-applied primers. Each of the primed groups was further divided into four groups to determine the effect of...

    Thus, a need arose for the development of surface finishes for CCA-treated wood that could address the special requirements of this substrate and provide protection against the ravages of water, sunlight, mildew, and other aspects of weathering and wear. Initially, this need was not addressed, most wood preserving companies had little expertise in surface finishes and...
