At Platinum Chemicals, one of the UK’s leading suppliers of Soudal products, we offer a carefully selected range of Soudal Glazing Sealants to meet the precise requirements of modern glazing applications.

Designed to seal the critical junctions between glass and window frames or between glass panes, this range includes both high-performance silicone and hybrid polymer sealants, all developed to deliver lasting flexibility, strong adhesion, and resistance to weathering.

Whether you are installing glass in aluminium frames, bonding glass-to-glass in a structural setting, or sealing wooden windows in a traditional property, Soudal Glazing Sealants provide a professional-grade solution every time.

Expert Sealants for Reliable Glass to Frame Sealing

As construction materials continue to evolve, glazing sealants must offer more than basic flexibility. They need to work reliably across a diverse range of surfaces, including modern PVC frames, powder-coated aluminium, treated timber, and specialist glass types such as self-cleaning panes. The Soudal range of glazing sealants responds to this demand with formulations engineered to maintain strong, primerless adhesion to both traditional and advanced substrates.

Products like Silirub 2 and Silirub LMN are low modulus, neutral cure silicones designed to provide exceptional flexibility and long-term weather resistance. They adhere effortlessly to a wide array of building materials—including glass, wood, plastic, masonry, and metal—and retain their performance even under constant exposure to UV rays, temperature shifts, and rain. These sealants are perfect for perimeter joints around windows, curtain walling systems, façade elements, and glass panel installations, accommodating movement while preventing water ingress and air leakage.

Tailored Solutions for Glazing in All Conditions

The glazing process involves more than just creating a watertight seal—it also demands compatibility with paint finishes, resistance to biological growth, and safe use in sensitive environments. Soudal offers a number of glazing sealants with specialist properties tailored to these needs.

Soudal SMX 506, for example, is developed using Soudal’s proprietary SMX® Hybrid Polymer technology and is specially formulated for use on self-cleaning glass, where traditional silicones can fail to bond. It offers excellent weather resistance and is entirely free from solvents, isocyanates, and acids, making it a modern, sustainable choice for high-performance glazing. It can even be painted wet-on-wet with waterborne paints for seamless integration into decorative finishes.

For traditional or general-purpose use, Silirub A offers an acetoxy-cure option that is especially effective in high-humidity areas or exposed outdoor joints. This product is resistant to mould and mildew, fast-curing, and compatible with smooth surfaces like glass, ceramic, and metal. Its high elasticity and low shrinkage ensure a tight seal, even under mechanical stress or environmental changes.

Specialist Silicone for Glass-to-Glass Bonding

In structural glass applications—such as glass displays, aquariums, terrariums, and frameless windows—bond strength, clarity, and chemical stability are paramount. Silirub AQ is specifically engineered for these tasks, delivering a strong, crystal-clear, fully waterproof seal that remains chemically inert once cured. This makes it completely safe for use in environments that house aquatic or reptilian life. Its high modulus formulation gives it the strength to handle internal pressure from water and weight-bearing glass structures while remaining permanently elastic and resistant to UV light, seawater, and cleaning agents.

Whether you’re fabricating bespoke glass units or repairing commercial aquaria, Silirub AQ provides the specialist performance and safety assurances required in such niche applications.

Seamless Application and Long-Term Durability

Each sealant in the Soudal Glazing range is designed for practical, on-site performance. With excellent extrusion properties—even in cold conditions—these sealants are easy to apply, tool, and finish. Fast skinning and curing times allow projects to move forward efficiently, and their long-term stability means less maintenance over time. Many are EC1+ certified for very low emissions, making them suitable for use in residential and sensitive interior environments.

Soudal’s formulations are also non-staining, which is particularly important when working with natural stone or decorative frames where visual impact matters.

Built on Trust, Backed by Experience

With decades of experience in hybrid and silicone technologies, Soudal continues to lead in sealant innovation. The Glazing Sealants range reflects this expertise, providing reliable, certified solutions that professionals can trust. Whether you’re working on new-build installations, restoration projects, commercial façades, or bespoke glazing tasks, these products are built to last—delivering airtight, watertight, and UV-stable seals that uphold structural performance and visual quality.
