Chemically, Preventol O 20 is a biphenyl derivative containing a hydroxyl group attached to one of the aromatic rings.
This structure enables the molecule to interact with microbial cell membranes and proteins, disrupting essential biological processes.
As a result, fungi and molds are unable to grow or reproduce on treated surfaces.

The antimicrobial mechanism mainly involves damage to cell membranes and inhibition of key metabolic enzymes in fungal cells, which ultimately leads to cell death.
Another important feature of Preventol O 20 is its optimized particle size distribution, which enables homogeneous mixing with mineral powders.

If antimicrobial additives are not evenly distributed, some areas of the material may remain unprotected and susceptible to mold growth.
The formulation of Preventol O 20 is designed so that the particles disperse evenly throughout the mixture, providing consistent antimicrobial protection across the entire material matrix.
