A New Choice For High Performance Heavy Duty Timbers
Tanasote™ S40 is a mineral oil based wood preservative containing copper and innovative organic co-biocides. It has been purposely designed to deliver up to a 40 year service life to high performance heavy duty timbers, such as railway sleepers and utility poles.
These are timbers that have the most demanding of end-use environments, so it was crucial that Tanasote™ S40 (more commonly referred to as Tanasote™) was designed to minimise early failures whilst providing a long service life.
In April 2021 Tanasote™ was launched in Europe following Biocidal Products Regulation (BPR) authorisation. This authorisation was granted following the wood preservative passing stringent risk assessments, as well as generating extensive data and studies to prove that it is effective against wood destroying fungi and/or insects.
Whilst the EN Standards have played a significant part in the development of Tanasote™, to prove real world performance in the most demanding of environments we have engaged in additional testing in copper-tolerant field test sites as well as laboratory fungal studies. Testing of water-repellent properties has also been undertaken.
A Focus on LCA
Looking specifically at utility poles, independent Life Cycle Analysis (LCA) results show that Tanasote™ treated wooden poles were the lowest impact pole type when compared against other materials.
