Solutions for today and tomorrow

Versatile, environmentally friendly waterborne adhesive dispersions

Waterborne adhesive technology has attracted significant attention as it is a more environmentally conscious approach to laminating and bonding. Water-based dispersions from Covestro have properties that meet or exceed those of traditional solvent-based systems.

Waterborne

Waterborne polyurethane and polychloroprene dispersions from Covestro provide improved adhesive processing and performance properties as well as a more sustainable profile.

Dispercoll® dispersions are used for one-component (1K) thermo-activated and room temperature, including wet-on-wet, bonding adhesives. They offer:

  • Excellent initial bond strength
  • High final bond strength
  • Good thermal, humidity and chemical resistance

One-component latent-reactive systems based on Dispercoll® U polyurethanes have the properties of two-component (2K) systems. They are utilized as dispersions, precoatings or reactive adhesive films.

Dispercoll® dispersions can also be formulated in combination with Desmodur® D isocyanate crosslinkers as two-component systems, providing the opportunity to fine-tune the final adhesive properties to meet challenging application needs.

Dispercoll® S nano-silica dispersions are used with Dispercoll® C polychloroprene dispersions to impart improved heat resistance and initial wet bond strength.

Compared to other water-based adhesive dispersions, our Dispercoll® products offer:

  • Lower odor
  • Greater storage stability
  • Good compatibility with other emulsion systems.

Dispercoll® waterborne dispersions find use in the durable bonding of textiles and leather in the shoe industry, foam bonding and 3D film lamination in the furniture industry. They also are ideal for heat lamination of automotive interior parts, and many more applications.
