Description

What is Soudal Silirub LMN used for?

Soudal Silirub LMN is a versatile, high-quality silicone sealant specifically designed for the construction and glazing industries. As a neutral cure (alkoxy) sealant, it releases an alcohol base during curing rather than acid, making it odourless and non-reactive. It is the industry standard for perimeter sealing of PVCu window and door frames, as well as expansion joints between common building materials.

 

Why Choose Low Modulus (LMN) Silicone?

The “LMN” designation stands for Low Modulus Neutral. In plumbing and construction, a low-modulus sealant is essential for joints that experience significant movement. Because it is softer and more elastic, Silirub LMN can stretch and compress without losing its bond to the substrate. This makes it far superior to standard acetoxy silicones for external sealing where thermal expansion is a factor.

 

Superior Adhesion and Durability

One of the standout features of this Soudal sealant is its primerless adhesion to a vast array of surfaces, including glass, PVC-U, timber, brick, and galvanised steel. It is chemically permanent and resistant to temperatures ranging from -60°C to +150°C. Whether you are sealing a conservatory roof or a bathroom expansion gap, Silirub LMN provides a professional, long-lasting finish that prevents water ingress and drafts.
