Teroson SI 113 Adhesive Flexible Sealant 300ml

TEROSON® SI 113 is a one-component moisture-curing silicone sealant specifically developed for sealing applications requiring outstanding resistance to mildew and fungal growth. Its non-corrosive alkoxy silicone formulation provides durable, flexible seals that maintain their performance even in permanently damp and demanding environments. :contentReference[oaicite:3]{index=3}

The product's thixotropic consistency ensures excellent non-sag properties on vertical surfaces, preventing migration after application. Once cured, it forms a highly elastic seal with elongation at break of up to 780%, providing exceptional movement capability and long-term durability. It is particularly suitable for sanitary installations, kitchens, bathrooms, ventilation systems and other moisture-prone areas. :contentReference[oaicite:4]{index=4}
