How to bond polyurethane

How to bond polyurethane?   Polyurethane (PU) is available in various guises – thermoform or thermoset and comes as a rigid solid, foam, or a soft elastomer. It is an easy-to-bond material, but adhesive selection is important to suit the type of PU being bonded.

Cyanoacrylates – All grades adhere well to PU.  Grades such as 2050 and 731 might be considered on elastomeric PU.   If bonding foam PU activator such as QFS16 or CSA-NF is recommended.

For bonding rigid PU, two component epoxy, polyurethanes, structural acrylics, and UV curable can be considered.

For a flexible bonding solution, look into MS Polymers.

How to bond polyurethane – Tips for surface preparation & bonding:

1. Providing the surface is clean and dry and free from contamination, PU can be bonded “As Received”.
2. If you do wish to do a solvent wipe before bonding or for clean up afterward, use isopropanol or Permabond Cleaner A; acetone is too aggressive and will attack the plastic.
3. For porous foam PU, select a product with appropriate viscosity. Elastomeric PU may require a flexible adhesive or cyanoacrylate.
