WHITEPAPER

THE CHALLENGE

Wood is a natural polymeric composite material, with a spectrum of useful properties. The use of wood in various applications, require treatment, to prevent weathering, decay and other forms of degradation, in order to extend the service life of wood products.

In current times, products with low toxicity and economic viability are more desirable, in order to prevent or prohibit the uncontrolled release/leaching of environmentally hazardous, toxic pollutants found in contemporary wood-preservation chemicals, that are harmful to human health, animals and plants. It is for this reason, that environmentally sustainable alternatives are necessary, for product protection and preservation in the wood industry.

WHY NANOTECHNOLOGY ?

NANOARC offers coating nanoadditives for wood protection in the form of quantum-phase nanomaterials , as effective broad spectrum tool for the protection of wood against mold or fungal decay, humidity-induced degradation and termites.

As wood preservatives, these atomically-architectured quantum materials are effective at low doses, to promote substantial results in terms of longterm protection, without causing colour changes to the wood or negative effects on the environment. Our nanoadditves help increase wood resistance against:

Leaching
Bacterial & Fungal/mold decay (in both dark and illuminated conditions)
Termites
Water absorption & volumetric swelling while increasing water repellency effectiveness
Ultraviolet (UV) radiation damage and resin yellowing
Marine Corrosion & Fouling
Heat Resistance & Flame Retardancy
Nuclear Radiation Protection

NANOPARTICLE SIZE MATTERS

Not only are nanoparticles important active components for wood preservation, they also act as carriers of preservative molecules from other compounds. As such, they can retain these wood-protecting compounds within wood, for extensive periods of time, through a slow-release mechanism.

PRESERVATIVE & NANO-CARRIER: The size of the nanoparticles matters in this regard, because in order to have a higher retention of preservatives over long periods of time in wood, the specific surface area of the nanoparticle has to be very high. Also, there should be no surfactants on the nanoparticle surface, as these reduce the effectiveness of preservative retention in wood. Reagent retention and delayed release over time in sapwood after a treatment cycle, is what provides a measure of the degree of protection provided by a treatment.

DISTRIBUTION AND PENETRABILITY: The next aspect, is that of the degree of penetration and uniformity of distribution of nanoparticles into the wood cellular structure, to actually protect and deliver additional preservative molecules. Studies show, that large nanoparticles (.i.e. > 10 nm) obstruct tracheids and inhibit the penetration of chemical reagents into wood. On the other hand, complete penetration and uniform distribution of preservatives within wood obtained when the nanoparticle size of the preservative is smaller than the diameter of the window pit (i.e. < 10nm) or membrane openings in a bordered pit (400 – 600 nm).

OUR OFFER

NANOARC offers ultra-high surface area, surfactant-free nanomaterials, for effective wood protection.

Essentially, with or without the addition of extra chemical agents, our nanoparticles are functional for wood protection and with dimensions below 10 nm, they offer a deep-level, lasting protection of wood, due to their enhanced penetrability and ability to increase wood resistance to rot or decay, chemical attack water- and thermal damage.
