Sikasil® WT-66 PowerCure

Application

Sikasil® WT-66 PowerCure has a wide adhesion range on many substrates such as glass,(coated) metal, wood, polyvinyl chloride (PVC) and many other substrates. In combination with its good mechanical properties, especially the high modulus of elasticity, this makes the adhesive most 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.

Description

An accelerated single component silicone adhesive for structural bonding of insulating glass units into window frames and for back-bedding applications. Sikasil® WT-66 PowerCure is applied using thePowerCure Dispenser and cures largely independent from atmospheric conditions.

Features and benefits:

  • Accelerated curing speed.
  • Excellent UV and weathering resistance.
  • Good mechanical properties.
  • Good gap-filling capabilities.
  • Remains flexible over a wide temperature range.
  • Long-term durability.
