Within the timber

Within the timber preservation industry revolutions are somewhat rare. Typically more Darwinist than big-bang in its technological advancement, the traditional principles of copper amine timber preservation have evolved rather than undergone a seismic shift. Micronized preservative technology, developed in the United States by Koppers Performance Chemicals, is in simple terms that seismic shift that fundamentally changes the timber preservation landscape. Whilst the pallete of active ingredients remain broadly identical (copper carbonate, quaternary compounds, azoles, etc.), it is the production process and preservative delivery vehicle that have undergone a radical transformation. Rather than dissolving the primary biocidal active, copper carbonate, in an amine solution, Koppers revolutionary approach, developed over a 15 year period, has been to micronize the copper carbonate through a series of complex milling processes to reduce the size of the copper carbonate particle, which is then suspended in a water-based solution. Koppers Performance Chemicals Micronized timber technology • No organic solvents, setting new environmental benchmarks (VOC free) • Improved compatibility with metal fixings and fasteners • Availability of a long lasting MicroShades pigmentation system Matthew Hempson, Koppers Performance Chemicals Business Development Director, says “MicroPro is a timber treatment technology which works differently, delivering at all levels of the supply chain. It ticks all environmental, performance, operational and aesthetic boxes.” also the preservative system of choice for a broad spectrum of applications (landscaping, agricultural, timberframe and particularly outdoor children’s activity equipment and public buildings). Paradoxically, in a society where appearance is paramount, it is its environmental profile which perhaps constitutes its greatest commercial attribute, enabling operational efficiencies and supporting commercial success, particularly in the specification sector. Micronized timber is both recognised by SCS, the international standards accreditation body, as an “Environmentally Preferred Product” and is UL GREENGUARD GOLD Certificated making it suitable for suitable for use in schools, offices, and other sensitive environments. The micronized technology brings with it some distinctive features, when compared to current copper amine based systems. • Faster drying • A clean, even light green colour, weathering to a darker attractive honey tan colour Whilst micronized technology is a relatively new development within the European timber preservation arena, the MicroPro micronized technology is the predominant treatment method within the United States and Australasia, with in excess of 20 million m 3 of MicroPro treated timber product sold to date, the equivalent of decking the surface area of the United Kingdom threefold. In short, the commercial proposition of Micronized timber is more than its aesthetic attributes; it is also one of substance, which will undoubtedly shift expectations and the market.

Whilst the aesthetic qualities make the preservative system a natural choice for visible applications, e.g. decking and cladding, with micronized pigment systems such as MicroShades adding further value, its operational and environmental credentials mean that it is IFC SPECIFICATION JOURNAL 2015-2016
