MK 3353

MK 3353 is a solvent-based nitrile adhesive with low viscosity suitable for bonding of a wide range of substrates.

  • Used in aeronautical industry for bonding metal with Velcro.
  • Employed for the assembly of a wide range of substrates including flat covering systems, loaded foam materials, aluminium and flexible PVC.
  • It can be mixed with the catalyst Mastikdur 0107 to increase the rate of reaction and the temperature resistance.
  • Free from: Toluol.
  • Excellent resistance to oil and grease.
  • Rapid grip and easy to use.
  • Excellent adhesion on different substrates, on many occasions without the use of specific surface primers.
  • Not suitable for surfaces exposed to UV rays through glass or crystal surfaces.
