Araldite 2021-1 Key Properties

  • Excellent adhesion to a wide variety of plastics, composites and metals
  • High shear and peel strength
  • Very good resistance to chemicals and water
  • Very fast curing and filling capacity
  • Suitable for use at temperatures up to 100ºC

Application of the adhesive Araldite 2021-1

  • The resin / hardener mixture is applied directly to the pre-treated and dried bonding surfaces.
  • With a layer of adhesive 0.10-0.20 mm thick, the shear strength will normally be imparted to the joint, although joints up to 4 mm thick can be assembled.
  • Note that adhesive layers with a thickness greater than 4 mm will react very strongly during curing, generating large amounts of heat.
  • The parts to be joined must be assembled and fixed as soon as the adhesive has been applied.
  • Uniform contact pressure throughout the bonding area will ensure optimum curing.

Other Araldite adhesives for Wind Energy

Huntsman fabricates and showcases a scope of authority adhesives for the Wind part which is suggested for use in the generation, support and repair forms.

Expanding efficiency in the drive to diminish process durations and cut expenses

Araldite epoxy innovations convey the qualities of long pot life, quick quality develop and high lap shear quality that wind industry applications request, commonly:

  • Shell Bonding
  • Repair, sealing and fixing
  • Binding.

Araldite adhesives offer speedier quality develop and a flexible bond that produces superior joints.

Low exothermic properties additionally upgrade execution through low shrinkage and decreasing of remaining worry in the completed joint.

Makers and administrators in the Wind energy business utilizing Araldite modern adhesives can, in this way, anticipate steady elevated expectations of execution, lessened downtime and higher profitability.
