MK 10-50 is a two-component polyurethane adhesive designed for the structural bonding of rigid plastic materials, ceramic materials, prepreg fibers.

  • High temperature resistance> 120 ° C
  • Thermosetting structural bonding> 15 MPa
  • Thixotropic and sandable
  • Hot modular reactivity
  • Low exothermic peak during hardening
  • Characterized by a very low shrinkage after hardening
  • Fair flexibility
  • Over-paintable
  • It can be used in various industrial sectors for bonding reinforced polyesters, ABS, polycarbonates and composite materials
