Würth Clear Neutral Cure Low Modulus Silicone is a professional-grade, versatile sealant suitable for glazing, window and door installation, façades and a wide range of general building applications.

Its neutral-cure, low-modulus formulation provides excellent adhesion to many commonly used construction materials while remaining permanently flexible after curing. The clear finish makes it particularly suitable for applications where a discreet, neat seal is required.

The silicone cures through contact with moisture in the air and is odour-free during application, helping to provide a more comfortable working experience. It is easy to extrude and smooth, allowing installers and homeowners to achieve a clean, professional-looking finish.

With strong elastic recovery and good resistance to ultraviolet exposure, Würth Clear Silicone is well suited to seals and joints that may experience regular movement or changing weather conditions.

Compatibility and adhesion may vary depending on the materials being sealed. Test on a small, inconspicuous area before use, particularly on sensitive, coated or porous surfaces. Always follow the manufacturer’s technical and safety guidance.
