SikaPower-4720 - Epoxy Structural Adhesive - Sika

SikaPower-4720 is a high strength two-component epoxy adhesive with excellent adhesion properties on a wide range of substrates.
It is specifically formulated for bonding metals and composite panels.

The glass beads present in the glue ensure a uniform and optimal minimum thickness of 0.25 mm.
It crosslinks at room temperature to form a rigid bond.

Features

  • High resistance
  • Good adhesion to a wide variety of substrates without primer
  • Long open time
  • Fast curing
  • Don't spin, don't sink
  • Can be welded (not cured)
  • Designed to achieve optimum bond thickness
  • Accelerated cross-linking under the action of heat
  • Low odor
  • Excellent corrosion protection
  • Solvent free
  • Black

Application areas

  • SikaPower-4720 is suitable for bonding panels in areas subject to high dynamic stresses such as side panels, door panels or roof plates.
  • SikaPower-4720 is not suitable for bonding structural parts such as uprights, sills and cross members supporting the engine.
  • The supports generally encountered for this type of bonding are metals, particularly aluminum (including anodized and rolled), cold rolled steel but also GRP panels.
  • Metals joined using SikaPower-4720 (still fresh) can be welded.

Application

  1. SikaPower-4720 is applied in uTAH 2 in 1 cartridges by means of a suitable piston gun.
  2. For homogeneous mixing of the components, a quadro mixer MGQ 10-19D 8.7 24 GT is required.
  3. At low temperatures (10°C), the cartridge must be heated before application in order to increase the extrusion speed.
  4. Prior to application, extrude the material without a mixer until both components emerge evenly to correct uneven filling.
  5. Then mount the mixer and extrude the first centimeters of glue bead which will be eliminated.
  6. To ensure complete wetting of the adhesive on the substrates, and therefore also to prevent corrosion, apply and spread the adhesive in a thin layer over the entire sanded surface of both substrates.
  7. Apply a bead of adhesive 5 mm from the edge to prevent the material from flowing (except at the welding points).
  8. Assemble the supports and first install the fixing brackets towards the corners.
  9. Then, if necessary, fasten with rivets or spot welding, or install fixing brackets every 10 cm.
  10. Single-sided application reduces open time and ultimate strength by up to 50% and may decrease the corrosion protection effect.
  11. SikaPower-4720 can be applied at temperatures between 10°C and 30°C.
  12. The product, supports and necessary equipment must be exposed to the same temperature ranges.
