DUNABOND HDU Adhesives are designed for today’s craftsmen and signmakers to bond HDU and other materials. Eliminate the need to stock multiple products in your shop – DUNABOND has been specifically designed for bonding CORAFOAM® HDU, but can also be used to bond virtually any material.

Ideal when a shorter working time is desired, DUNABOND 3206 is a solvent-free, waterproof, single-part urethane adhesive with a working time of 15-18 minutes.

Common materials that can be bonded with DUNABOND include:

  • Expanded materials (polyurethane, polystyrene, phenolic, etc.)
  • Metals
  • Fiberglass laminates
  • Wood
  • Concrete
  • Ceramics

DUNABOND are flexible, structural adhesives that can withstand temperatures from -40°F through +176°F. Flexible adhesives offer a benefit over rigid adhesives in that, in addition to bonding, they can also be used to fill, seal, waterproof, reduce vibrations and absorb the expansion and contraction of different materials. They can also easily adapt to critical environmental conditions, from very cold to very hot temperatures.

 Surface Preparation

In most cases, a thorough cleaning is enough for DUNABOND polyurethane adhesives. Remove all traces of dust, dirt, grease or any other loose material. Materials other than HDU may require one or more of these additional steps:

  • Blasting or Grinding
    Smooth surfaces offer less “tooth” or grip than rough ones. In order to get the bond you need, it may be necessary to blast, sand, or grind the surface. Blasting or grinding is also recommended in cases of obvious traces of corrosion, oxides, rust, paint etc. After blasting or grinding certain materials, a degreasing operation may be necessary to completely remove remaining abrasives. If you use compressed air to remove dust from surfaces, be sure to use a filter and check it to ensure that there are no traces of oil (which could subsequently affect adhesion).
  • Degreasing
    It’s advisable to degrease surfaces of certain materials before and after blasting or grinding. Degreasing can be performed either by washing with a solvent, or by applying the solvent using clean cloths or brushes. Cloths should be changed frequently, or you will run the risk of spreading the grease around, instead of removing it. Once the surfaces are cleaned, they must be allowed to dry completely. This will eliminate traces of solvents which could affect subsequent adhesion.
