Zendol B3

The growing global concern for environment, biodegradation and toxicity issues imposed extremely high standards for each new biocide. ZENDOL B3 is a state-of-the-art product that conforms to the highest requirements as concerned by BPR, CLP and REACH.


The advantages of using ZENDOL B3 are demonstrated by the unique qualities of the composition:

  • wash proof -
  • ZENDOL B3 ensures long-term timber protection, even in conditions of high humidity (it doesn’t get washed off the wood’s surface). This quality is attributed to its extremely low solubility in water, combined with the increased wood absorption conferred by the active ingredients.

  • various and multiple applications -
  • the product can be applied in common wood treatment procedures on different wood products and risk classes: wood joinery, wood in contact with soil, logs and timber.

  • extended biological action -
  • efficient action against a wide range of moulds like surface moulds, rotten and blue stain moulds, insects.

We provide technical support for our product, to help our customer identify the cause of possible problems and find solutions to improve technology.
