Waterborne


Waterborne dispersion adhesives are by far the largest class of adhesives in terms of volume. Water is the most important and by far the cheapest solvent. It is also non-toxic and easily disposed of, and does not harm the environment.


Formulation of water-borne dispersion adhesives is more complex than that of solvent-borne products. The end properties of the adhesive are determined mainly by the chemical composition of the base polymer dispersion. Resins (up to 30 percent) can serve to increase tack, and fillers (up to 60 percent) can be used to reduce costs. Antifoams help reduce unwanted foaming during production and application of the dispersions.

Advantages

  • Low toxicity

  • Variable formulation properties

  • High solids content

  • High initial adhesion

  • Little or no solvent

Applications

  • Automotive industry (interior fittings such as headlinings, dashboards, etc.)

  • Shoe industry (bonding of sole to upper, toecaps, inner soles)

  • Construction industry (various flooring materials)

  • Furniture industry (for decorative lamination of wood)

  • Mattress industry

  • Paper and packaging industry
