New Treated Timber Colour Technology

June 2021

With specifiers and consumers increasingly wanting more colour options for their treated construction and garden timbers, we have launched TANALITH LIFESTYLE – a new range of in-solution colours for TANALITH preservative treatments.
The images of treated cladding shown above are for illustrative purposes only.

Available in three contemporary colours – Brown, Dark Brown and Grey – the TANALITH LIFESTYLE range is designed as an adaptable and easy to use additive to regular TANALITH preservative treatments of Use Class 3 and Use Class 4 pine construction, fencing and landscaping timbers.

Andy Hodge, Marketing Director at Lonza, explains the thinking behind the new TANALITH LIFESTYLE technology:

‘Our existing TANATONE brown colourants for use with TANALITH preservative have proved to be incredibly popular and successful with our customers to give their markets a different initial colour choice to their high pressure treated timbers. However, we have been increasingly asked for an improved longevity to the colours as well as the inclusion of a new grey colour option, which is very much in-vogue.

The new TANALITH LIFESTYLE products will sit alongside the existing TANATONE range and provide a high performance colourant option, specially developed to give longer colour life when used with our TANALITH preservative. We are confident that the new TANALITH LIFESTYLE colours will have a typical colour life of up to two years, depending upon location and exposure to UV light, as well as still allowing the treated timbers to achieve the usual desired service life expectations from a preservative point of view.’

TANASOTE – innovative wood preservation for heavy duty industrial timbers

June 2021

TANASOTE S40, Lonza Wood Protection’s new oil based wood preservative, has gained Biocidal Products Regulation (BPR) authorisation for its use as a high performance treatment for the long-term protection of heavy duty industrial timbers, such as utility poles, railway sleepers and hard landscaping timbers.

Authorisation for TANASOTE S40 has now been granted in both Sweden and Belgium. Further authorisations throughout Europe and the UK will follow shortly.

Developed as a hot oil/copper based technology with an innovative and powerful new co-biocide to protect against a wide spectrum of aggressive copper tolerant decay organisms, TANASOTE S40 (more commonly known as TANASOTE) has an excellent industry fit as it can be used in existing or new creosote type plants and provide an assured service life of up to 40 years.

Dr Stephen Uphill, Technical Lead – Application & Innovation for Lonza’s European Wood Protection business commented: ‘If the timber industry is to keep wood as a primary material of choice in important high risk applications, it needs to be bold and adopt modern and innovative BPR approved alternatives that will confidently deliver both high performance and sustainability.’

‘TANASOTE is an exciting and proven alternative that will meet these criteria. An innovative preservative system from our experienced development team, TANASOTE is designed to meet the future needs of the high performance timber sectors and is now a real alternative for the agricultural, utility pole and railway sleepers industries whilst meeting the stringent risk assessments of the BPR.’

‘Three independent life cycle studies have been conducted with excellent resulting credentials across the board for TANASOTE compared to competing materials such as steel, concrete and fibre glass. And all the ancillary properties, such as conductivity and corrosivity of metal fixings, highlighted by the markets sectors are all similar to traditional creosote treated timbers.’

Whilst going through the intensive BPR authorisation process, TANASOTE treated timbers have been placed in various industry relevant field trials around the world to prove its performance credentials. The new preservative has also been used in full scale commercial treatment trials to fine tune its application and required protection levels across a wide range of timber species.

Andy Hodge, Lonza’s Marketing Director, summed up the exciting prospects for Lonza and timber markets across Europe. ‘Creosote has a long history as a powerful and effective wood preservative. However, from a regulatory point of view, its safety and environmental credentials have been under a severe review for quite some time. Its continued use has been allowed from a socio-economic standpoint because there has not been a viable alternative to provide long term preservative protection to these heavy duty timbers.’

‘Oil based TANASOTE, as well as tried and tested, water based copper organic preservatives for some market applications, now provide these viable and sustainable alternatives, from both a performance point of view but also in delivering an advanced environmental profile.’
