Sealant Soudal silicone universal 310 ml transparent — neutral cure, general-purpose

Soudal universal silicone sealant in a 310 ml cartridge is a transparent, neutral-cure product designed for general sealing and bonding tasks. It forms flexible, watertight joints that resist weathering and maintain adhesion to many common construction materials. The sealant is supplied ready-to-use for manual or pneumatic caulking guns and is suitable for indoor and outdoor applications where a neutral-curing silicone is required.

Advantages

This neutral-cure silicone cures without releasing acetic acid vapours, reducing the risk of corrosion on metal surfaces and odour in enclosed spaces. It provides long-lasting elasticity that accommodates typical joint movement and maintains an effective waterproof barrier. The formulation offers good adhesion to glass, glazed and painted surfaces, ceramics, and many plastics when used on clean, compatible substrates. Its transparent finish ensures discreet joints and preserves visible surfaces.

Suitable for

• Sealing window and door frames
• Sanitary joints around sinks and baths (non-structural)
• Sealing construction and expansion joints
• Bonding and sealing glazed surfaces and glass panels
• General-purpose sealing where a neutral cure is preferred

Key specifications

• Packaging format: 310 ml cartridge suitable for manual or pneumatic caulking guns
• Cure type: neutral/alkoxy neutral cure (non-acidic)
• Color: transparent
• Property: elastic, waterproof and weather-resistant joint after curing
• Application temperature range: suitable for typical ambient and substrate temperatures encountered in building works (check product label for exact limits)
• Substrate compatibility: adheres to glass, glazed surfaces, painted wood, many metals and some plastics when surfaces are clean and primed if necessary

How to use

Ensure joint faces are dry, clean and free from dust, grease, loose particles and old sealant. Cut the cartridge nozzle to the required bead size, insert into a compatible caulking gun and apply a continuous bead of sealant into the joint. Tool the joint within the skin formation time to ensure good contact with substrate and a smooth finish. Allow the sealant to cure fully before exposing the joint to water or mechanical stress; cure time depends on bead size and ambient conditions. Follow any additional surface preparation, primer and curing details provided on the product label.

Usage recommendations

For best results, test adhesion on unfamiliar substrates and use a compatible primer where required. Avoid use on substrates that bleed oils, plasticizers or other contaminants. Store cartridges in a cool, dry place and use within the manufacturer’s recommended shelf life. When sealing sanitary areas that require fungicidal protection, choose a product specifically formulated for sanitary applications if needed.
