Adhesive PU-2A

Adhesive PU-2A is a two-component polyurethane adhesive developed for bonding metals (aluminum alloys, steel), non-metallic materials (fiberglass, foam plastics), as well as combined joints (metal + non-metal). It features high strength, heat resistance and resistance to aggressive environments.

Main purpose and application

PU-2A adhesive is intended for bonding metals (aluminum alloys, steel), non-metallic materials (fiberglass, PS-1 type foam), for bonding parts made of acrylic glass grades SO-95, SO-120, SO-140, AO-120, and acrylic glass of the same grades with nylon or lavsan fiber tapes, as well as metals and non-metals to each other.

Main application areas:
Aviation:
  • Bonding parts made of aluminum alloys (D16AT), acrylic glass with nylon/lavsan tapes.
Industry:
  • Bonding fiberglass, foams, metal-composite structures.
Special purpose:
  • Sealing and anti-corrosion protection.
