MK 1520-N

MK 1520-N is a solvent-based polyurethane adhesive particularly suitable for bonding PVC – Hypalon and other synthetic materials.

  • Particularly used in the nautical sector.
  • Recommended for the assembly of PVC and Polyurethane materials.
  • Used for bonding Rubbers, TR (thermoplastic material), synthetic materials, thunit (elastomer), leather, and simil-leather.
  • Free from: Toluol.
  • Rapid grip and easy to use.
  • Heat re-activated for bonding of particularly difficult to bond materials.
  • 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.
