Paint-destroying fungi

Table III Activities against paint-destroying fungi...

TBTN exhibits fungicidal and algicidal activity and has been used as an active ingredient in antifouling paints and wood preservatives. The fungicidal activity of TBTN directs preferably at wood-destroying fungi. Due to the lower tributyltin content compared with TBTO (19.5.) approximately double the addition rates have to be applied. 

A loss in viscosity occurs when enzymes, organic catalysts manufactured by bacteria and/or fungi, start to destroy the thickener. These enzymes are capable of triggering reactions quickly and for indefinite periods. One enzyme molecule can effectively change millions of raw material molecules to undesirable end products. The result can be a paint or coating that loses its elastic and elonga-tional properties.
