Product Description

1.POLYURETHANE SEALANT Lejell220
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 so it's doing great in sealing two different kind of material surface. Easy to apply. The textured consistency is ideal for use in sealing applications requiring a rough appearance.


Product Features
One-component, excellent extrudability, no sag, easy construction.
High modulus, good anti-water pressure performance.

Areas of application


Suitable for areas where low movement, high resistance to penetration and pressure are required.
For water proofing of air face on bridges, tunnels and drainage pipe. For precast panel, concrete internal wall and stone bonding and sealing.
