Features and benefits

  • 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

Constraints

  • 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
