Single-component PU sealant Lejell220 is a moisture-cured, 1-component, polyurethane-based, non-sag elastomeric sealant capable of ±25% joint movement. It's moisture curing with super good bonding performance. High modulus allows it to perform excellently in sealing two different kinds of material surfaces. The textured consistency is ideal for use in sealing applications requiring a rough appearance.

◈

Product Features: One-component, excellent extrudability, no sag, easy construction.

◈

Performance: High modulus, good anti-water pressure performance.

Areas of Application

Suitable for areas where low movement, high resistance to penetration and pressure are required. Ideal for waterproofing of air face on bridges, tunnels, and drainage pipes. Also used for precast panels, concrete internal walls, and stone bonding and sealing.
