Even after a short operating time, extreme damage to concrete and steel can occur due to the extensive chemical attack of the highly corrosive biomass and biogas. Furthermore, the use of herbal and animal waste material such as pomace, slaughterhouse waste, slop, fat and oil increases the corrosiveness of the substance.
Conventional coating systems for biogas plants provide inadequate corrosion protection. Solvent-based coating products cause, for instance, osmotic blistering and the so-called washed out concrete is induced by insufficient acid resistance. Concrete erosions of 1 to 2 cm and extreme corrosion damages on all steel components are measured per year.
Through several years of intensive research in corporation with an independent institute, we have developed special internal coating systems for biogas plants, which provide a steady long-term protection against biocorrosion induced by SRB-bacteria. The unique mode of operation has been internationally patented. For more information, please refer to the topic "Biocorrosion".

Our new "winter-systems": Applications at winterly temperatures down to minus 10°C
The combination of specific fillers and reactive hardener compositions enables the use of our winter product series during dry winter seasons with ambient temperatures down to -10°C. These special coating systems are still sprayable even under these conditions and they cure within 2-3 days completely. After 7 days of curing, the coated surface is generally chemical resistant, thus largely preventing temperature-dependent down times.
Even with this special feature, the physical properties of our high-performance products remain intact. Besides excellent chemical resistance against high corrosive liquids and gases at elevated temperatures, our solvent-free "winter systems" provide an outstanding adhesion on steel and concrete substrates. Because of their direct application without use of a primer, new buildings and renewals of biogas plants can be conducted efficiently during the winter season. An absolutely innovative product line on the international market!
