## Summary description

Soudal SIL N SO BI is a 310 ml construction silicone sealant with neutral curing in white. Designed for sealing joints and gaps in building applications where neutral cure is required, it adheres to common substrates and provides flexible, weather-resistant sealing.

## Long description

Soudal SIL N SO BI 310 ml is a neutral cure construction silicone sealant in white formulated for flexible, weather-resistant sealing of joints and gaps in building applications. It bonds to a wide range of common substrates used in construction and renovation, providing durable elasticity that accommodates joint movement while resisting discolouration and environmental influences. The product is supplied in a cartridge suitable for use with standard caulking guns and is intended for both interior and exterior applications where a neutral curing chemistry is required.
Advantages
The neutral cure formulation minimises the release of acetic acid or corrosive by-products, making the sealant compatible with sensitive materials and metal finishes. It offers good adhesion to glass, painted surfaces, ceramics and many common building materials without the need for a primer in many typical situations. The cured silicone retains elasticity over time, maintaining watertight and weatherproof joints and resisting UV exposure and microbial growth in sanitary applications.
Suitable for
Sealing glazing joints and window perimeters
Sanitary joints around sinks, baths and sanitary fixtures
Exterior and interior general joint sealing in facades and trims
Sealing gaps between dissimilar materials where neutral cure is necessary
Key specifications
Colour: white
Packaging: 310 ml cartridge
Curing type: neutral (oxime/neutral) silicone
Elastic, permanently flexible seal
Resistance to UV exposure and weathering
Suitable for interior and exterior use
How to use
Ensure joint surfaces are clean, dry and free from dust, grease or loose particles. Cut the cartridge nozzle to the required bead size and apply with a standard caulking gun, filling the joint evenly. Tool the sealant within the skinning time to achieve a smooth finish and ensure contact with both sides of the joint. Allow the sealant to cure fully according to ambient temperature and humidity; curing time may vary depending on joint depth and environmental conditions. Remove uncured sealant with a suitable solvent; cured silicone should be removed mechanically.
Usage recommendations
Use Soudal SIL N SO BI in applications where a neutral curing silicone is recommended, especially on metal or coated surfaces sensitive to acidic by-products. For best results, test adhesion on unfamiliar substrates and observe joint design guidelines: maximum recommended joint depth and width ratios to ensure proper curing and long-term performance.
