MK EP 520

MK EP 520 è una resina epossidica bi componente (resina + indurente)

MK EP 520 is a two-component epoxy resin (resin + hardener) not loaded indicated for the bonding of different materials.

Mainly used for bonding metals (aluminum, steel, iron) and composite materials.

  • Suitable for the assembly of rigid plastics, marble, porcelain, ceramics, costume jewelery stones, hard woods, glass and ferrite.
  • Average setting time
  • Rapid repair even at temperatures close to 0 ° C.
  • Solvets free
  • Resistant to bases, diluted acids and poor to solvents.
  • No shrinkage
  • Excellent adhesion on different substrates, without the use of specific surface primers
