Description

Permabond® UV640 is a one-part, medium viscosity, fast-curing UV adhesive. It cures colorless and completely transparent under the influence of UV light at longer UV wavelengths.


Difference to Permabond® UV630

Permabond® UV640 has a higher viscosity, specifically for greater gap-filling capacity.


Suitable substrates

It is particularly well suited for the following substrates:

  • Plastics in particular (including those with UV stabilizers)
  • glass
  • metal


Suitable applications
  • Applications with different thermal material expansions
  • Applications where flawless aesthetics are paramount


Advantages of Permabond® UV640
  • Very high shear and impact resistance
  • Very high elasticity
  • Curing "on demand"
  • Fast curing even at low lamp power
  • Solvent-free
