Soudal Silirub LMN Silicone Cream White 300ml – Low Modulus Neutral Sealant

Soudal Silirub LMN Cream White is a professional-quality, low-modulus neutral-cure silicone sealant designed for demanding glazing, construction and weather-sealing applications.

Its highly elastic formulation accommodates movement while maintaining a durable, weather-resistant seal. Silirub LMN provides primerless adhesion to most common construction materials, including glass, plastics, masonry, metals and wood, making it particularly suitable for perimeter sealing around windows and doors.

The Cream White finish provides an attractive alternative to brilliant white where a softer, warmer colour is required.

Key features

• LOW MODULUS NEUTRAL CURE – Professional silicone formulation designed for flexible building and glazing joints with high movement requirements.
• HIGH MOVEMENT CAPABILITY – Allows up to 25% joint movement and remains permanently elastic after curing.
• EXCELLENT ADHESION – Primerless adhesion to most common construction materials, including glass, plastics, masonry, metals and wood.
• WEATHER RESISTANT – Excellent resistance to UV, rain and snow, making it suitable for exposed exterior sealing applications.
• WIDE TEMPERATURE RESISTANCE – Resistant to service temperatures from approximately -60°C to +150°C.
• FAST CURING – Fast skin formation with a curing speed of approximately 2mm per 24 hours, depending on conditions.
• ISO 11600 F&G 25 LM – Suitable for professional façade and glazing applications requiring a low-modulus sealant.
• CREAM WHITE FINISH – Ideal for coordinating with cream-coloured windows, doors, frames and exterior building finishes.

Typical applications

Soudal Silirub LMN is suitable for a particularly broad range of professional sealing applications, including perimeter sealing around windows and doors, glazing joints, expansion joints, roofline and drainage systems, aluminium glazing systems, curtain walling, façade panels, lead and slate roofing, HVAC ducting, pipework and drainage joints.

Its combination of flexibility, weather resistance and adhesion makes it particularly well suited to window installers, builders, roofers, glazing professionals and general construction trades.

How to use

Ensure surfaces are clean, dry and free from dust, grease and loose contamination before application.

Apply using a standard manual or pneumatic caulking gun and tool the joint before skin formation to achieve the required finish.

Soudal specifies an application temperature between +5°C and +35°C. Where adhesion is critical or unusual substrates are involved, carry out a preliminary compatibility and adhesion test.
