Polysulfide Sealant for Insulating Glass


The polysulfide sealant is two-components, solvent free polysulfide sealant, specilized for insulating glass’ installation.polysulfide sealant

Features:
  1. Cured in room temperature
  2. Solvent free,low boiling point
  3. Strong adhesion for glass,aluminum, steel and most of building material.
  4. Good aging resistance.
  5. Non pollution to environment

Range of usage:
The polysulfide sealant is used for manufacture insulating glass, it suitable for both automatic production lineand manual operation. The polysulfide sealant also can good work together with butyl sealant.

Properties:


No.

NOTES

  • Polysulfide sealant can’t mixed with silicone sealant, because the adhesion of mixed sealant not stable.
  • The operating temperature should not below 5℃, because the curing time will be influenced when below 5℃.
