- Chemical resistance : Seawater, cement, diluted alkalis, and water based detergents
- Excellent adhesion to most substrates
- Weather resistance, excellent aging resistance
- Movements capability of ±50%
- High tear strength
- One component, excellent workability
- Can be painted over
- weberseal PU cannot be used as a glazing sealant
- Do not use weberseal PU on bituminous substrates, natural rubber,
- EPDM rubber or on building materials which might bleed oils, plasticizers or solvents which could attack the sealant
- Colour change may occur in time because of UV exposure, but this has no effect on the mechanical properties of the cured product
- The adhesion is low on PE, PP, PTFE
- Not resistant to organic solvents, organic acids, high concentrated alkalis/acids
