Efficiency against Fungi
Micro-organisms are omnipresent in our environment and have the ability to grow
even under unfavorable conditions. This makes the use of micro-biocides necessary
in order to provide long-term protection against growth on surface coatings.
The choice of a suitable biocide and its optimum dosage require knowledge of the
micro-organisms that may grow.
Typical contaminations by fungi
Fungus ( also known as mold) will develop on any paint surface which is periodically
moist and which can provide sufficient nutrients. In practice this means that, without
a fungicide, all external coatings films are liable to fungal colonization unless
they are located in very dry situations. Fungal growth on a paint film normally
appears as dark spots on the surface and is sometimes confused with dirt. As well
as disfiguring the surface, the organism can actually penetrate the film and make
it more permeable to water. Growth can also develop under the film and cause loss
