DOWSIL 994

 

PRODUCT DESCRIPTION

Szczeliwo silikonowe DC 121

TWO COMPONENT NEUTRAL ULTRA FAST CURING SILICONE SEALANT, specialized silicone sealant designed for automatic bonding processes including Window Bonding applications and solar panels bonding, where immediate adhesion has been required. Provides excellent primerless adhesion to wide range of construction materials, including glass, PVC, aluminum or wood.

 

FEATURES & BENEFITS

  • Ultrafast curing system – curing speed depends on mixing ratio
  • Flexible mixing ratio (base-catalyst) allows to meet exactly the nedded curing speed
  • Excellent adhesion to many construction surfaces
  • Able to resist structural loads
  • High joint movement capability factor (MAF)
  • Neutral curing system – no odour, no corrosion
  • Excellent resistance to aging, ozone and UV
  • Wide range of working temperature
