BEKO Universal Silicone Transparent 22401 310 ml Cartridge Silicone Pro4

For sealing jobs that demand a crystal-clear finish without compromising on durability, the BEKO Universal Silicone Transparent 22401 stands apart from typical acetoxy sealants. Its high-transparency formulation blends invisibly into glass, ceramic, and light-coloured surfaces, while the permanently elastic cure absorbs movement that would crack rigid fillers. The 310 ml cartridge fits standard caulking guns and flows smoothly for clean, professional beads in both indoor and outdoor applications.

Highlights

• Transparent acetoxy silicone for nearly invisible seals on glass, tiles, and sanitary fittings
• Excellent adhesion to non-porous metals, ceramics, and many plastics without primer
• Permanently elastic with ±25% movement capability – ideal for expansion joints and glazing
• UV and weather resistant for long-term outdoor durability
• Waterproof and mould-resistant once cured, suitable for kitchens and bathrooms
• Skin forms in 5–15 minutes; full cure approx. 2–3 mm per 24 hours

In daily use

Apply with a standard cartridge gun at temperatures between +5°C and +40°C. The silicone skins over quickly, allowing tooling within minutes, yet remains workable long enough for precise smoothing. Once cured, the seal withstands temperatures from -40°C to +150°C, making it suitable for both cold storage and hot water pipe surroundings. The transparent colour keeps the focus on the surface, not the sealant – a real advantage for glass-to-glass joints, shower screens, and display cases.
