New wood preservative developed in NZA New Zealand company, Mattersmiths Holdings Ltd, has developed a new wood preservative. The inventor, Paul Maynard, is a Director of the company and holder of a range of patents relating to compositions for treating wood and processes for wood preservation.
With some similarity to ACQ, the new preservative is water based containing copper with the option of a range of co-biocides. It can be used in standard wood treatment processes and according to Mr Maynard it is a world first and has a number of advantages over traditional wood treatments.
It’s simple to manufacture and eliminates some of the petroleum based components otherwise used in such compositions. Those that are used for replacement are natural renewable materials offering an improved HSE profile. Fixation is rapid and leaching of biocides is reduced the corrosion of fixtures used in service is reduced, the colour of treated wood is considerably lighter and the ‘fixed’ preservative has very low solubility under normal conditions but is bioavailable at the physiological pH of decay fungi.
The new preservative has been tested by an independent laboratory using soil contact techniques and studies demonstrate bioperformance is equal to or better than current preservatives in use. Patents are being have been applied for globally and for further information, contact email@example.com.
