Application

In combination with its good mechanical properties, especially the high modulus of elasticity, the adhesive is particularly suitable for structural bonding of insulating glass units into window frames and for back-bedding applications. It is further suitable for highly demanding industrial bonding and sealing applications.


Sikasil® WT-66 PowerCure has a wide adhesion range on many substrates such as:

  • Glass.
  • Coated metal.
  • Wood.
  • Polyvinyl chloride (PVC).
  • Many other substrates.


Description

Sikasil® WT-66 PowerCure is an accelerated one component silicone adhesive for bonding insulating glass units or glass panes into a window frame and for back-bedding applications. It is applied using the PowerCure Dispenser and cures largely independent from atmospheric conditions.  


Features and benefits:

  • Accelerated curing speed.
  • Excellent UV and weathering resistance.
  • Good mechanical properties.
  • Remains flexible over a wide temperature range.
  • Suitable for bonding of windows classified according DIN EN 1627 burglar resistance class RC 2 and RC 3.
  • Fulfils requirements according to RAL-GZ 716 part 2, table 3 (PVC and glass) and ift-guideline VE-08/4, part 1, table A4.
