Raw materials make a 3D difference

Heat-activated polyurethane raw materials for 3D furniture lamination

Demand for 3D laminates is growing due to their ability to create unique 3D designs. These laminates offer an economical alternative to solid wood for home owners while their durability is attractive for retail and office furniture.

3D Furniture Lamination
Heat-activated adhesive raw materials for 3D furniture lamination

The adhesives used to bond 3D laminates to composite wood substrates, typically medium density fiberboard (MDF), have a significant impact on appearance and durability.

In the thermoforming process, heat is used to activate the adhesive, which forms strong bonds to the laminate film and the MDF. Polyurethane adhesives have the ideal properties for 3D laminating applications. 

Covestro offers a range of high-quality water-based polyurethane raw materials for the formulation of 3D laminate adhesives:

  • Heat-activated solutions based on Dispercoll® U polyurethane dispersions and Desmodur® D polyisocyanate crosslinkers
  • One-component (1K) latent reactive solutions based on Dispercoll® U polyurethane dispersions and surface-deactivated solid isocyanates

Our polyurethane raw materials for 3D laminate adhesives offer several advantages:

  • Activation at low temperatures
  • Short resting times in the lamination press, resulting in a more efficient process
  • High initial and final bond strength
  • Fast-setting properties that resist the restoring force of deep-drawn films directly after the laminating press is opened
  • Several types of films can be laminated, including plasticized PVC
  • Good heat resistance and long-term durability
  • Easy application using common methods, including spray coating
  • Good storage stability, even after application
