👷 📋 The Master Fitter's Verdict

"When you're sealing expensive laminated safety glass, roof glazing, or complex timber-glass facades, you cannot risk a blowout or foil delamination caused by cheap, incompatible sealants. The S 10 is my strict standard for structural glazing. It's completely non-corrosive against bare metal frames and won't interact with PVB sheets, saving you from catastrophic, expensive call-backs."

Pro Tip: Thanks to its incredible primerless adhesion on most glass, timber, and metallic substrates, S 10 dramatically speeds up your application time on large conservatory builds or commercial installations.

Why the Professionals Choose OTTOSEAL S 10

• Laminated Glass Safe: Fully compatible with PVB sheets according to ift guideline DI-02/1, guaranteeing it will not degrade or delaminate safety glass (VSG) edges.
• Non-Corrosive Formula: The advanced neutral-curing system ensures it will not cause corrosion on unprotected metal surfaces like aluminium, steel framing, or lead.
• Extreme Tear Resistance: Highly resistant to notches and tearing, making it perfect for structural expansion joints subjected to high mechanical, wind, and thermal stresses.
• Primerless Adhesion: Forms a highly aggressive, durable bond on most smooth glass and metallic surfaces without the need to apply an additional primer.
