• 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
