In response to the growing awareness of end consumers to make more eco-sensitive choices and the resultant shifting demand by treaters for an alternative to metal-based solvent treatment products, Lonza Wood Protection introduced Vacsol Azure to the South Africa market as the first metal-free wood preservative in the light organic solvent sector.

Eight years later, this new generation preservative still holds full market share as the only alternative with environmental advantages over its predecessor solvent-based wood preservative products – namely TBTN, TBTO-L and PCP.

“The key attribute of promoting the use of more wood in construction is that it is a truly renewable resource which plays a vital role in reducing the carbon footprint of a building, as wood products store carbon for the duration of the product’s lifetime. But equally important to choosing wood in construction is the decision to use a metal-free, organic-based wood preservative,” says JJ du Plessis, business manager at Lonza Wood Protection South Africa.

Since the launch of Vacsol Azure in South Africa, the demand for the product has grown exponentially and du Plessis provides insight into the reasons behind its success.

“The facts speak for themselves. Vacsol Azure has achieved a solid track record of performance excellence in the organic solvent treatment segment for H2 and selected H3 hazard classes. We attribute this success to its innovative design that ticks all the boxes for treating re-manufactured, appearance, and engineered wood products where both moisture content during processing and water repellence in the end-use product are critical. As a result, the last eight years has seen Vacsol Azure become an essential component of wood preservation in the South African market,” says du Plessis.
