OTTOSEAL S 100 – The premium sanitary silicone

In the sanitary sector, as well as in construction in general, silicone is an everyday tool of the trade. Whether for joints between tiles, for sealing transitions that must have a certain elasticity or also in the glass area, silicones are used in most cases. As soon as moisture plays a role, it is also important to pay special attention to the addition of sanitary or wet zone in the silicone used to ensure resistance to water and other liquids and to prevent mold and fungal attack.

In order to be able to offer you an outstanding product with first-class quality and reliability, we would like to introduce the product OTTOSEAL S 100 from the German manufacturer Otto-Chemie in this article.

Reliable silicone for inside and outside – made in Germany!


For well over a century, Otto-Chemie, a manufacturer founded in Berlin, has been dedicated to the production of sealants, adhesives and fabrics with a clear focus on the craft sector. Thus, there is also always the claim to the highest quality and reliability without compromise. The OTTOSEAL S 100 sanitary silicone is no exception. This is confirmed not only by the IVD seal of approval and Baubook Austria, but also by EMICODE® EC 1 Plus, the French VOC emission class A+, as well as a high rating according to building certification systems, which attest to the silicone’s excellent sustainability values. The award and conformity package is rounded off by tests passed in accordance with EN 15651 – Parts 1 to 4, EN 13501: Class E, and conformity with Regulation (EC) No. 1907/2006 (REACH).

With these basic data, the OTTOSEAL S 100 should easily meet all the requirements of professional and demanding construction and craft projects. But there is no need to compromise on the actual application either. Key data such as very good weathering, aging and UV resistance and excellent processing properties, which make the product eminently smoothable and moldable, result in a silicone you can fully rely on.

Variety of colors for any application

Furthermore, OTTOSEAL S 100 Sanitary Silicone is available in over 80 colors. In addition to the usual white, gray, black and beige shades, there are also more exotic representatives such as various yellow, red, green and blue shades to meet more unusual requirements.
