The OTTOSEAL® S 100 Silicone Silver Grey Glossy (C94), Item No. 13116, is a top-tier choice for professionals seeking a reliable, durable sealant for use in wet areas. This sanitary silicone impresses with its excellent properties and easy application, making it an efficient solution for all sealing work in sanitary environments. With high resistance to moisture, mould, and UV rays, it ensures lasting, precise, and resilient seals.
The OTTOSEAL® S 100 Silicone is a high-quality 1K silicone sealant based on acetate, suitable for both indoor and outdoor use. It is especially valuable in areas exposed to frequent high moisture levels or extreme temperature conditions. Typical applications include:
Joint sealing in bathrooms, showers, and other wet rooms
Sealing of connection and expansion joints in wall and floor areas
Bonding of profile glass and glass blocks
With excellent workability and the ability to mould the silicone, you can easily adjust and smooth it, achieving a clean, professional finish every time.
A standout feature of this silicone is its mould and bacteria resistance, achieved through a special additive that prevents mould and bacteria growth. This ensures that your sealant remains stable and hygienic. This protective feature also lasts under regular use and typical conditions in wet rooms.
The silicone also boasts excellent resistance to UV radiation, weather conditions, and aging. It remains dimensionally stable even in extreme outdoor temperatures, retaining its sealing properties for years. Sun, rain, or frost have no impact on the material.
Another remarkable feature is the high elasticity of the product. With a total deformation of up to 50% according to ISO 9047 and an allowable elongation of up to 25% according to EN 15651, the silicone is ideal for applications in areas subject to constant movement and expansion, such as those caused by temperature changes or mechanical stress.
The silicone also offers excellent temperature resistance, ranging from -40°C to +180°C. This makes it an excellent choice for both indoor and outdoor use.
Thanks to these features, the OTTOSEAL® S 100 provides a reliable, durable, and flexible solution for all sealing work in wet areas.

Before use, thoroughly clean the substrate and check its cleanliness. Ensure it is dry and free from grease or oil. For optimal adhesion on non-porous materials such as glass or metal, we recommend using a suitable cleaner. In some cases, especially with glazed ceramics or stainless steel, a primer may be required to further enhance adhesion.
After the silicone has cured, maintenance is straightforward. Regular cleaning with a soft cloth is sufficient to remove dirt and protect the sealant from mould growth and wear.
For even easier application, we recommend accessories such as smoothers and primers to optimise adhesion to special substrates.
The OTTOSEAL® S 100 Silicone is the ideal choice for professionals who rely on long-lasting seals. With its high elasticity, UV and weather resistance, as well as its mould resistance, this product is perfect for professional use. Trust in a product that reliably and permanently protects your sealing work, even under challenging conditions.
