MK EP 500

MK EP 500 is a two-component epoxy resin (resin + hardener) with no fillers 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 stones, hardwoods, glass and ferrite
  • Rapid repair even at temperatures close to 0 °C
  • Solvents free 
  • Resistant to bases, diluted acids
  • No shrinkage
  • Excellent adhesion on different substrates, even without the use of specific surface primers
