310ml/600ml High Modulus Polyurethane Sealant for Construction PU Sealant
Description:
This is a multifunction gun grade polyurethane based construction sealant, it is of high modulus and cures by reaction with atmospheric moisture to form a soft rubber like material with moderate elasticity and high adhesion strength.
Applications:
- 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.
Features:
- One-component, excellent extrudability, no sag, easy application.
- High modulus, good anti-water pressure performance.
