Product Benefits

Versatile application conditions:

  • Shows high initial strength and fast setting which makes the product ideal for difficult to bond substrates.
  • Low application temperatures from +120°C allow bonding of more heat sensitive materials. It also potentially provides energy cost savings.
  • Suitable for profiles with tight curvatures.

Temperature resistance:

  • High heat resistance after complete curing up to 150°C depending on the surface materials
  • Good cold resistance
