Soudal SMX506 Self-Cleaning Glass Sealant

(Choice of colour)

Protects self-cleaning glass: durable, flexible, coating safe.

A hybrid polymer glazing sealant, based on SMX®-technology, designed for self-cleaning glass. It provides excellent adhesion on common frame materials including wood, PVC, and aluminium. Ideal for window installs and replacements where long-term, UV-resistant performance is required.

This solvent and isocyanate-free sealant bonds securely without primer, even on slightly moist surfaces. It is easy to tool and can be painted wet-on-wet with most water-based paints. Intended for glazing joints on specialist glass like Pilkington Activ Glass™ and SGG Bioclean ®, it is not suitable for continuous water immersion or contact with materials like EPDM or bitumen.
