Soudal Professional Neutral Cure Silicone Sealant

The Soudal Silirub range offers high-performance, low modulus neutral cure silicone sealants designed for professional glazing, construction, and industrial applications. These versatile sealants provide a permanently elastic seal with high movement capability, making them ideal for expansion joints and perimeter sealing in both indoor and outdoor environments.

Engineered for ease of use, these sealants feature a fast skinning time and excellent toolability, allowing for a smooth and professional finish every time. The neutral cure chemistry ensures the product is non-corrosive, making it safe for use on sensitive substrates including coated metals, anodised aluminium, stainless steel, uPVC, and most common glass types (excluding self-cleaning glass). Its superior weather resistance protects against UV radiation, rain, snow, and temperature extremes without degrading, cracking, or losing adhesion.

With outstanding primerless adhesion, this silicone bonds securely to a wide variety of construction materials such as masonry, brick, concrete, treated timber, and various metals. Whether you are working on modern facade panels, roofline systems, or window and door frames, it delivers a durable, long-lasting seal that stands up to the elements.
