Key Features & Benefits

Formulated for Sanitary Applications

Soudal Sanitary Silicone is purpose-built for wet and humid environments, making it the ideal choice for use in bathrooms, kitchens, and other areas where consistent moisture is present. It prevents water ingress and resists the development of mould and mildew, ensuring hygienic and long-lasting seals in sanitary installations.

Acetoxy Cure Technology

Utilizing acetoxy-curing technology, the silicone cures rapidly on exposure to atmospheric moisture, forming a flexible, waterproof seal. This type of curing system is known for excellent adhesion to non-porous surfaces like ceramic, glass, glazed tiles, porcelain, and aluminium.

High Movement Capability

With excellent elasticity and movement accommodation, this sealant remains flexible after curing, enabling it to adapt to joint expansion and contraction caused by temperature or structural movement. This makes it suitable for sealing between tiles, fittings, and fixtures, where daily use and environmental changes can affect structural integrity.

Clean Finish Options Clear and White

• Clear Silicone: Ideal for discreet applications, especially where the sealant needs to blend seamlessly with surrounding surfaces.

• White Silicone: Offers a clean, bright finish, perfect for matching bathroom fixtures like white tiles, sinks, toilets, and bathtubs.

Strong Adhesion on Non-Porous Surfaces

This silicone bonds extremely well to smooth, non-absorbent substrates commonly found in bathrooms and kitchens. Its non-shrinking, non-cracking formula ensures a robust and aesthetically pleasing seal over time.
