Sista Schimmel Blocker (Henkel AG & Co. KGaA)

It happens in almost every household: Stains emerge in the shower and mold discolors the joints and silicone sealings. Not only does it look unaesthetic, but the joints are also being damaged and the fungal spores create a health risk. Normally, silicone sealing compounds equipped with fungicides are used in moist rooms, such as bath rooms. However, those fungicides used in such silicones are usually washed out fast and the fungistatic effect quickly decreases.
Resulting from this: mold spores adhere to the silicone compound and then they spread. The joints discolor and mold becomes visible. The standard sanitation silicones, which are most often applied, wear out after 1 or 2 years already, and in case of inadequate air ventilation you can count on a mold infestation even sooner than that. In order to fight mold Henkel researchers analyzed its life cycle. Now they can take action against mold during different phases of its growth – starting from the first spore accumulation to germination and fungal growth, all the way to spore formation, discoloration and spreading. The result - “Sista Schimmel Blocker Aktiv-Silikon” - is a brand-new active silicone with a triple-active-protection that was newly developed by Henkel. Henkel KGaA asked SGS INSTITUT FRESENIUS, an independent and competent laboratory service provider, to perform regular quality analyses in the hygiene field and to test and certify the special triple-active-protection in comparison with other competitive products. SGS INSTITUT FRESENIUS confirms that ‘Sista Schimmel Blocker Aktiv-Silikon’ is „the best sanitary silicone of its class“ thanks to the new, innovative triple-active-protection.

Basis for the awarding of the SGS INSTITUT FRESENIUS Quality Seal are regular quality tests:

Assessment of the test procedures which were developed to verify the long time mold resistance of 'Sista Schimmel Blocker Aktiv-Silikon' in comparison with competitive products. During these tests the sealing compound is examined in order to find out whether or not it still shows a sufficient mold protection despite ageing and water impact.
Supervision of the microbiological tests regarding mold growth after having treated 'Sista Schimmel Blocker Aktiv-Silikon' with common cleaning agents
Examination of the product ingredients concerning critical components
Supervision of the adhesive strength tests carried out with 'Sista Schimmel Blocker Aktiv-Silikon' on critical PMMA-surfaces in comparison with competitive products
Audit of the production facility

Manufacturer’s information

Sista Schimmel Blocker – the best sanitary silicone of its class

Sista Mould Blocker is the first and the only available active sanitation silicone with a 5-year guarantee against mold.

Sista Schimmel Blocker distinguishes itself due to a completely new technology, namely an especially developed triple-active-protection. The triple active-protection is a real innovation in the field of sealing compounds and consists of a special ingredient combination of fungicidal and non-fungicidal active agents which keep joints free of mold for 5 years.
