Preventing Decay and Maintaining Dimensional Integrity
SurfaPore W is a water-based nanomaterial specifically designed to protect and preserve absorptive wood without changing its natural appearance. At the same time it allows it to silver naturally. Because moisture cannot penetrate the wooden surface dimensional stability and protection against decay are achieved. This nano sized barrier is vapour permeable and allows equilibrium between the timber and the ambient atmosphere that minimizes shrinking and expansion and thereby reduces warping and cracking. The lack of residual moisture virtually eliminates mould, mildew and lichens from growing, preventing decay. The life of the timber is extended.
Inline Manufacture Process or On Site Application
SurfaPore W can be applied as a final protective coating on wood that requires a natural look, or as a primer for other water based coatings, including paint, stains and varnishes. Oil based stains can be successfully applied either before or after SurfaPore W. Water based fungicides and pesticides (borate is a good example) can also be mixed with SurfaPore W based on specific recommendations by NanoPhos.
Industrial application of SurfaPore W includes spraying, dipping and injecting during inline processes. For example, in the manufacture of chipboards, injecting SurfaPore W immediately prior to pressure treatment and the heating chamber is a proven method of application without intrusive and costly handling.
How does it work?
Our nanomaterial consists of three types of differently sized nanoparticles, each with its own purpose. The smaller nanoparticles penetrate the capillaries and bond with the hydroxyl groups of the cellulose content to provide long-term protection against water ingression. The second group of nanoparticles penetrates the appropriate depth to react with organic resins that reside in the wood. The third type is a nano-emulsion of paraffin that ensures enduring surface protection.
Water beading is NOT a good indicator of protection
Water beads hovering over a crack in wood is certainly impressive, but it is not a true indicator of moisture protection. Beading occurs because when it doesn’t have anything to cling to, it clings to itself, creating self-contained drops. SurfaPore nanoparticles create a hydrophobic barrier so water on a treated surface has nothing to cling to but itself. In time, beading becomes intermittent and sometimes goes away altogether because debris and oils accumulate on the surface. Water is attracted to that and is distributed throughout the surface “rubble” reducing or even eliminating surface beading. Areas of high foot traffic can abrade the top layer of a treated surface, reducing the effective water repellency on the surface. The rule of thumb is that when water is visibly darkening the wood SurfaPore W should be reapplied.
How to Apply
Surface should be dry and clean. Apply with brush, roller, by spraying or dipping. Do not dilute. Allow SurfaPore W to soak for at least 30 seconds or until wood is no longer absorptive. Use second coat only if wood remains absorptive. Remove excess by wiping with a soft rag. Leaving excess to dry might result in a tacky surface, which can be removed with hot water. Maximum water protection is achieved after 24 hrs. Recommended application temperature is above 5°C. Coverage: Estimated coverage is 6-8 m2 per litre, strongly dependent upon the absorptive properties of the surface.
Properties: Milky white, water emulsion. Minimal or no change to appearance of surface applied. Test on a minor surface area before applying. Avoid freezing. Can be stored in its original container for 24 months after production date. Contains nanostructured silicon compounds <10% w/v.
Safety: Dispose of this material properly. Keep out of the reach of children. In case of contact with eyes or skin, rinse immediately with plenty of water and seek medical advice. Always request, read and comprehend the Material Safety Data Sheet of the product before application.
International Standards TestingSurfaPore W was tested for dimensional stability according to ASTM standards:
It takes more than 2500 hours for water beading failure in a combined UV-moisture chamber.
*Areas of high foot traffic can abrade the surface, thereby reducing the duration of protection. Re-apply as needed.
